I'll check 'em. Since it's working in reverse though, shouldn't that mean 
all those connections are fine? My understanding from the schematics is 
that the forward/reverse relay reverses the direction of the field (ok, 
reverses the direction of the current that makes the field) to swap from 
forward to reverse, but the same connections on the motor itself are used. 
No? If that's the way it works, it seems like the connections at the motor 
should be fine. I think.

Which are the RTN (Return to Neutral, I think?) contacts?

I assume the kickplate is the plate just in front of where you sit? :) If 
so, I've become somewhat familiar with things down there as I've poked 
around. I've sprayed the connections with De-Oxit, but haven't loosened 
and retightened all the connections.

Armature resistor guard? Do you mean the connections to R1 and R2 on the 
"screen" above the charger?

Thanks,
