Chosen Solution
I have a 2007 R&T 4-seater electric golf cart. A week ago, when I would step on the accelerator the cart would try to move forward but chattered terribly. Usually, the motor would kick in and run smoothly with the help of a push. Eventually, though, the cart wouldn’t move at all. I could hear the solenoid clicking when I depressed the pedal, but nothing else happened. I replaced the solenoid on a hunch. Now it still clicks, but the cart shows no sign of movement at all. The batteries are old and all show a charge of 8.1v. They were functioning just fine before the “chatter” issue evolved, but did not hold a charge for very long. Is that the “obvious” issue? I know less about electrical systems than I do quantum physics, and I can’t afford to throw money hand over fist just replacing parts. I don’t know if I need a new motor, controller, batteries, or just a diode. Can somebody please help? Thanks.
The problem turned out to be the brushes on the motor. Two of the 4 brushes were burned due to poor contact, which resulted in the “chattering” I was experiencing.
@shaverin , Steve, Does sound like a faulty battery/connection issue. Found some info. at the link below.May have loose connection somewhere, check/clean/reseat all connections and check all fuses. Have batteries checked, have a load test done on the battery bank,as batteries could be bad if all connections good. Controller could also be defective. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. http://scducks.com/forum/showthread.php?…
Same issue with 2009 R&T 4 wad. Rode around about 30 minutes at a relatively low speed to preserve power stopped put it in reverse it tried to move but could not. Noticed status light blinking on controller. Pulled it home jacked the back up pushed the accelerator the wheels turned about half turn cut off in forward and reverse. The pack charge was at 49.1 volts. All batteries are at least at 8volts. Checked all cables found to be ok. I have a spare motor and controller is their a way to test before removing and replacing. Thanks Heyward
