Re: (ET) GE controller

[Tim Maxwell <timmaxwell chartertn net>]

I have bench tested controllers (no experience with GE brand 
controllers) using the bench testing procedure from the Curtis 1204 
manual. It has worked for me with both Curtis and Alltrax controllers

Basically you need:
a dc power supply (either leads from a battery pack with a 10A inline 
fuse or a transformer)
a throttle pot (any 0-5k ohm, doesn't have to be a true potbox) or 
whatever throttle type the controller expects
a power switch/power disconnect
a main contactor
a test load (I use 3 incandescent 12v tail light bulbs wired in series)

Wire the light bulbs in series to the controller in a circuit like a 
permanent magnet motor.
The diode checks and other diagnostics listed in the Curtis and Alltrax 
manuals be able to be applied to the GE units.
