Hi,
I have a 1993 Club Car 36V golf cart I'm trying to resurrect for a
charitable organization. I hooked up some batteries to test it out and
it worked for about a minute, then the contactor just clicked on then
off immediately and nothing happens after that. Disconnecting the
battery and reconnecting is the only way to get the contactor to
"click" again. I've checked every microswitch, cleaned the throttle
pot, cleaned the F-N-R mechanical switch contacts, verified that the
contactor works properly when run independently. The series motor
brushes and armature are in excellent shape, and runs fine. I finally
tracked down the Curtis 1204 controller manual and went through the
troubleshooting steps and the best I can determine is that the
controller is not working. During testing today I noticed that the
precharge resistor would get rather hot. Then the contactor quit
clicking on then off like it used to and the resistor no longer would
get warm. Obviously I'm talking about when the contactor was open.
Voltage to the inputs on the controller were normal but there was
never any voltage or current on the output.
It appears that I need to replace or repair the controller. If it were
my golf cart, I'd just buy a $150-$200 clone and call it good but I
don't want it quitting on someone else. Would I be best to ship it to
Curtis or someone like cloudelectric.com to be rebuilt? I haven't
found any used or new Curtis 1204 controllers available.
Thanks,
