Hi Everyone:
I am a newby here so please excuse my ignorance. I need help! I have a Yamaha G22 electric cart. It was not in the best shape when I bought it, but that is what happens when you pay $800. It used to run just fine, but recently cannot move. The symptom that lead up to the issue of not running was pretty strange (IMO). When it started to act up I could push the cart with foot on the throttle, it would the 'click' and whine and it would start moving. Unfortunately, even that trick no longer works and the cart will not move under its own power.
The issue really started after I replaced and cleaned a few items. The replaced electrical parts were the solenoid, batteries, and high tension wires. The cart worked fine initially, but quickly migrated to the non-running condition. The solenoid does not give that distinctive 'click' now, but does seem to work with 48 V applied directly. The batteries are outputting 53+ volts. I checked the obvious parts, The accelerator stop switch was replaced along with the throttle pot. Neither of them seemed problematic after testing, but I replaced them since they were old. The ignition and direction switches were checked and operate correctly. I am concerned now that it is the expensive controller, but I want to make sure it is actually the problem before I pony-up the $$$. I have not checked/replaced the speed sensor yet since I am not sure how to do that.
What should I check next, and how? Is there any detailed information that is available for the internals of the controllers that may be helpful? Sorry for the novice question(s), I just don't know what to do next.
Thanks,
John
