I have a G22E Yamaha electric gold cart. I played 18 holes yesterday, came home plugged it in and mowed grass, I went to go again later and backed out of the garage ok but when I pushed forward the golf cart stopped and acts like the batteries are dead. I tried tow button off and on and nothing. I found the fuse and it is good, it sparked also so it has juice. I looked for loose wires and found none. For about six months there has been a buzz (to me like a stuck solenoid) but when it was taken in in February for a tuneup I asked the guy and he said it was normal? I tried checking with a meter some connections but the schematic in the owners manual isn't much. Do you have and suggestions what to check and or how. Thank you very much.
