This instructable is meant for owners of RepRap and other 3d Printers which use 2 stepper motors for the Z axis, as commonly seen in the Prusa or Mendel styles of printers, among many others. The default configuration for most controller electronics such as RAMPS is to have the motors connected in parallel. However as I will attempt to explain, it can be more beneficial to connect the motors in series instead. So the purpose of this instructable is to describe a method of creating a "plug and play" wiring harness that will convert your motors from parallel to series.
Pictured are conceptual diagrams which hopefully illustrate the path of the circuit and how this makes the motors series connected.

On my printer I used DRV stepper drivers which don't behave very well with parallel wired motors. Due to some specifics about how the driver works it basically ends up "skipping" parts of the microstepped waveform. That's not to say it misses any steps and loses its position, just that it flattens out parts of what should be a smooth sinusoidal current waveform making for louder more jerky operation.
This is particularly noticeable if autoleveling is enabled on your printer. Autoleveling compensates for a bed which is not parallel to the toolhead movement by constantly making small Z adjustments as it moves across the X and Y axes. In my case this caused very audible "pop" sounds from my Z motors as it skipped a bunch of microsteps during a print.
For a way more detailed and technical explanation of what's going on and another solution to the issue involving diodes, see this informative blog post. Here is a list of items used to build my harness. If you find this instructable useful and require any parts or tools, using these amazon affiliate links for your shopping would help me out.
The jumper wires typically come in a ribbon of 40 wires at a time, and you can peel away contiguous strips of any number. This project only requires 4 such wires. I find these style of jumper wires incredibly handy for electronics protoyping and tinkering, they are great for connecting arduinos, breadboards, and other quick connections. As long as your wires have female on at least one end it will work here. Peel 4 wires from your breadboard jumpers with female endsfold in half and clip in the middle.
Take a side with female connectors, and splay out the wires and strip a small amount from the ends about the length of the shorter side of the header pins. Make sure the wires are peeled backed far enough that the heatshrink won't get heated during soldering. Placing these pins on a breadboard with the longer end facing into the breadboard helps to hold everything in place while its being worked on.
Wiring Your Z Stepper Motors in Series
Pictured is a random Arduino shield with built in breadboard. Now two pairs of diagonal pins will need to be electrically connected, as shown. I do this by carefully bending them toward each other, and then soldering with a small amount of solder. Tweezer nose pliers are helpful here as they can fit in very small spots.
Care should be taken when bending and soldering these pins as they can slide up and down in the plastic header the breadboard helps somewhat to keep the pins from slidingn.
If the heat from the soldering iron is left too long it can melt the plastic holder causing the pins to fall loose, and you may need to start with a fresh header piece. Also when soldering, avoid globbing on too much which could cause unwanted bridging to other pins, space is somewhat tight.Not much changed over the years from through but there might be some small nuances between the years. This tutorial will go over all aspects of Project This truck was complete so it was a candidate for a minor restoration.
Complete does not mean Serviceable however. Almost nothing on this truck was serviceable. That being the case, anything having to do with Electrical Wiring is addressed in this article. If this is too in-depth for you, that would be the reason. We will start at the front of the truck and move towards the back to make things as sequential as possible.
In our case, we do not even know what voltage headlights are in the buckets, let alone the condition of them. This is true for the condition of all of the associated electrical system parts.0b5 transmission
Start by removing the headlight trim piece with one Phillips screw at the bottom. Assess the condition of the seal that is inside of that trim piece. If necessary, replace the trim seal. Remove the nine 8 sheet metal screws that hold the Headlight Bucket Assembly in the fender.
Since we are replacing the wiring harness, cut the wires to the headlights so you can get them out. Now is when you need to decide if you want to install new headlights at the same time as the harness. With the headlight removed, we can separate the inner bucket assembly. With a pair of needle nose pliers, pull up and outwards on the spring. Once the spring is no longer holding down the inner bucket, remove the two special adjustment screws and the special nuts from the slots they are in.

Now you can cut and toss the old headlight grommet. With everything separate, assess the condition of the bucket parts. I found lots of rust and the parts were in pretty bad shape. With all of the parts looking like new, I then added the headlight grommet to the back of the bucket, reinstalled the bucket parts together and inserted the buckets in their respective holes.
The Harness comes with two very nice headlight harnesses for installation through the inner fender as shown. With the headlights squared away, next we will attack the Park Lights. Since we have decided to use the turn signal wiring that comes standard with our harness, we need to do a modification to the original Park Lamp Housings.
The bulb socket will no longer reside inside the housing, rather, it will be mounted behind the housing. You will want to mark and then drill the second mounting hole. To make the housing fit nicer upon installation, I took a small hammer and bent the new adapters mounting plate around the outside of the housing. Once it is tightened securely, I found this really easy to do without ruining anything. The new lamps have sort of a nuance that I didn't realize until I got slightly frustrated. They need to go in only one way so the pegs on the side of the bulb are offset as is the bulbs socket.
If you can't get them to click into place, turn them degrees! You need one lamp for each housing.Universal Diesel Wiring Harness Upgrade previous page pages 1 2 next page If your Universal engine panel looks like this, and has an ammeter, you are due for some wiring fixes. The factory wiring, with an ammeter in the panel, is flat out dangerous and this really needs to be addressed if it has not yet.
It amazes me how many boats are out there still using this unsafe set up. Another alternative is to run your alternator direct to the house bank with a fuse or breaker within 7" of the battery and then add a combining relay or Echo Charger. I have also measured voltage drops of 1.Ssl proxy video
That means your alt is putting out Here's a very crude diagram that shows the alternator charging circuit most often found on these early Universal engines. Interestingly enough most of the Westerbeke engines never used a factory installed ammeter and it was sold as an option.
The factory charging circuit leaves the alternator with an orange 10GA wire then most often travels through TWO trailer type connectors to an ammeter at the engine panel.
This high amperage current then has to travel all the way back to the battery switch please not I did not draw the battery switch on this diagramthrough more undersized wire, where it finally picks up some larger gauge wire before finally heading to the battery to charge it.Web api async await example
These factory circuits often had a 30A fuse in them which was undersized even for some of the alternators shipped on these engines. Owner often put higher amp fuses in or bypassed them all together. On most of these panels the entire current of the alternator runs through 10GA wire and a ridiculous trailer type connector that is a huge point of resistance as these boats age.
I have pulled many of these connectors and wires out that were literally melted. With house power demands getting larger and larger and battery banks getting bigger and bigger, and accepting significantly more charging current, these circuits have been known to literally melt down and in some cases catch fire and this is all with stock alternators.
Here's the quick and dirty fix. Try to focus on the red wire between the back of the alternator and the starter post. Simply jump the alternator output to the starter post and disconnect the orange wire. Minimal voltage drop compared to the 10GA circuit and much less resistance and heat without going through all that small wire and two trailer connectors.
Please note that I generally advise running the alternator output directly to the house bank, not to the starter as shown here. You can then install an automatic combining relay ACR or an Echo Charger between the banks to charge both simultaneously. Doing this will remove the potential for fried diodes via the flipping of the battery switch through the OFF position. Even if you choose not to run the alternator direct to the house bank you are far safer with the new jumper than you were before.

Because installation works related to electricity scary many vehicle owners away, they prefer the experts at trailer shops to have the job done for them instead of trying to figure out how things work. While the basic configuration is a 4-way flat connector that features one female and three male ends, you may come across connectors with up to seven pins for additional functions that require wiring, including electrically actuated brakes, power source for a winch, etc.
This is the most common scenario. It has three poles for basic functions running lights, turn signals, and brake lights and one pin for the ground. This connector is commonly found on most light-duty trailers. When wiring trailer lights, make sure to route the harness away from anything that could damage the wires. Trailers longer than 15 feet and heavier than 1, lbs must have a brake system — that means another circuit for hydraulic brakes.
The fifth wire blue is meant for reverse lights; this connection is needed to disconnect the hydraulic trailer coupler or actuator when the vehicle is backing up, thus deactivating the brakes on a trailer. Apart from providing basic functions, this connector has 2 more ports for electric brake control blue and 12V power supply black or red.
Now that you know the types of connectors, you have to determine what you have on your vehicle to make the connection to a trailer. They developed a universal trailer connector that has been used on their vehicles since the s. To determine how to wire up trailer lights, you need to know whether your vehicle has a factory-installed trailer package and whether a plug-and-play T-connector is available for it on the market.
As a matter of fact, the aftermarket offers harnesses to join two connectors of any type. Even if your vehicle is not equipped with a connector, it may have a wiring plug located in the rear.
Depending on the model, the location may vary from inside of trunk to under the rear floor panel. If there are absolutely no provisions for trailer lightsyou are electrically inclined or have a rough idea of how to wire trailer lights, you might consider splicing into your existing wiring. In this case, you will need a set of wiring taps and a pair of pliers. To connect the electric system of your trailer to the vehicle, you will be using special connector.
Above we have describes the main types of trailer wiring diagrams. Below is the generic schematic of how the wiring goes. Note, that this type of 4-pin connector is less common, that 4-pin flat connector. As a rule, you can find these connectors on the older trailers and older vehicles built in the U.
At the moment, neiter tow vehicles nor trailers are equipped with round 4-pin connectors from the factory.DIY LED Light Bar Harness - How-To Make Your Own
As a rule, 5-Way flat connectors are used for trailers that feature surge brakes or hydraulic brakes. The extra wire, as a rule, is used to power backup lights. When it is plugged, it disengages hydraulic trailer actuator when you reverse, so the trailer brakes are off at that moment.
A very good explanation what the black wire in the 7-way connector is for. I couldn't find the explanation in 4 more sites I reviewed. Thanks for the help!

Then reality sits in. We'll see what kind of boost Cowboys get from a win and a few days off, but this one will be a struggle to put away. Sure, the Giants will get a little surge from the return of Eli Manning as the starting quarterback and the coaching change. But the Giants have won only two games for a reason. And with nothing to play for, the Giants' early-game boost won't have staying power.
The Cowboys need to win out.Dar ki paribhasha
They take control in the second half and pull away. The playoff scenarios already look dismal, but the recent win over Washington offered a peek of hope with a month of games to play. A loss to the reeling Giants would rip right back open the wounds of the not-too-distant three-game losing streak and all the questions that came with it.
Dallas postpones that uncomfortable day at least another week.
The Cowboys would appear to be slam-dunk winners against the hapless Giants. In the NFL, however, rarely is anything is as it appears. The Cowboys rally in the fourth quarter against the Giants and their new starting quarterback. Dan Bailey kicks the game-winning extra point.
