Re: (ET) advice needed

I'll take a shot.

1. First most electrical problems are due to bad connections. Wiggle wires
first. Good places to check are the reversing relay and field connections 
to
the motor.

2. Working lift, lights, and accessory outlet means the basics are ok, but
that leaves a fair amount unchecked.

3. You mention not seeing voltage at the contactors. On the coil contacts,
relay contacts, both? Please explain a bit what and how you are measuring
here.

4. If the reverse relay is actually clicking, then you have power to the
control board and Fuse 3 is ok.  The fuel gauge shoudl be indicating if 
Fuse
3 is ok.  Assuming this is true then you need to walk thru the motor
circuit.

5. With motor drive on (and gearbox in neutral and hair, etc out of range 
of
the belts and pulleys) check voltages at the motor armature and field
connections. If they aren't present there then back up thru the 2A, 1A, and
L contactors.

I assume you have the schematic. It is very helpful in tracing things out.
