How to easily trace your wiring

How to easily trace your wiring.
So you've got a bad coin accepted light on your door, and you're not sure where it goes.
There are a couple of ways of tracing that wire.
You could clip one lead of your ohm-meter onto the wire, and then start poking the other lead into all the pins on your Beau plugs until you find one that ohms-out.
Pretty time consuming.
Or, you could pull out those beau plugs, and look behind them until you find the wire color you're looking for. Always a bad idea, because you will weaken the integrity of the plug and the wires. don't dick around with your beau plugs unless absolutely necessary, please.

Or you could do it the easy way. Every wire goes somewhere, either to the door, reel mech, hopper, top unit, or case.
So, if you're looking for an 18 wire (red with black) from the door, then pull out your reel mech, gently set it on its back, and look at the wiring side of you beau plug until you find it soldered in place. If it's not there, then pull out the hopper, and look again at the wire side of your plug to see if you can find it.
And then do the same with the top unit, and finally look at the wiring in the cabinet. All wires go somewhere.
Bally tried very hard to maintain its wiring integrity, so please remember that wires to not magically change color in the loom. Color changes occur accross switches, and not arbitrarily in the harness.
Once you have noted down the correct location on your plugs, then you can go in with your meter from plug to plug to ensure that you have a good circuit.
This method can save you a lot of time when shotgunning, and also, if you want to, you can easily make a drawing of all your plugs wiring so that you can use it as a reference for further problem solving.
It's also a good idea to learn the Bally color code as a shorthand method for following wiring.
1=red
2=blue
3=yellow
4=green
5=white
6=brown
7=orange
8=black
9=grey
0=no trace.
Print it out and use it as a handy guide.
Or, remember the following phrase "Red Blooded Yankee Girls Wear Brown Or Black Garters.
