92 marathon wont go - controller?
92 ezgo marathon controller cart stopped this weekend as I backed out of garage. Took off a full charge, hit the gas and it jerked in reverse but died immediately. Solenoid clicks but nothing else. I have taken the following measurements/ tests:
- pack voltage 38.4v
- 6.4v on each battery
- pot box went from 0 ohms with pedal up to 6500 ohms with pedal fully depressed - gradual climb with pedal
- pack voltage at battery side of solenoid with key on
- pack voltage at controller side of solenoid with pedal down (? below)
- pack voltage at b- and m- terminals on controller with pedal pressed enough to engage solenoid; voltage does not budge as pedal is fully depressed
? on solenoid from above - I measure about 27v on controller side of solenoid with pedal up and solenoid not engaged - is this normal/residual power stored in controller? I have not disconnected the wire from solenoid to controller.
I welcome any ideas and suggestions. JohnnieB this is a continuation of thread earlier today.
Thanks to all!
Brandon
