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
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
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
3 is ok. Assuming this is true then you need to walk thru the motor
5. With motor drive on (and gearbox in neutral and hair, etc out of range
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
I assume you have the schematic. It is very helpful in tracing things out.
E12S (pretty much like your E15)
