Daniel, that sounds like the makings of a nice little nightmare. You almost hit the trifecta - you had 12v electrical, water... All you would have needed is a flat tire or steering wander!

1. The step motor runs fine when hooked up to a 12v source on my bench.
2. The step motor won't run at all when connected via jumpers to the (good) 12v supply at the step. (This is coming from the chassis, NOT thru the controller.)
3. Aaaand, the kicker: #2 was killing me, so finally I hooked up my voltmeter to the jumper ground & 12v that I'm using at the rig. I get 12+ volts when the jumpers aren't hooked to the motor leads. As soon as I touch a jumper to the motor lead, my 12+ volts goes to zero. HOW? The motor runs fine on the bench.

Somebody, please put me out of my misery! HAAAAALP!
It doesn't take an engineer to solve that problem. Any time you lose voltage when you present a load on a curcuit there is a bad connection somewhere.

A voltage drop test would be the most efficient here. It would tell you every thing you need to know. I use it in the marine industry to diagnose this type of problem all the time.

One thing I have learned on 12 volt wiring is throw away the volt meter.Use a high amperage test light,you can have voltage on a meter.But you may not have enough of a current to light the test light.ck fuses for connections with test light for the same reason.
