2007 Drive, no clicks, no reverse buzzer, batteries ok

[rcat8872]

Hey guys,
I did several searches before posting. All four batteries have been tested multiple times by multiple friends and seem to be ok. Reverse buzzer does not work and no clicking from solenoid. I cleaned and double checked every connection I could find. Reset tow/reverse switch multiple times and I cleaned all connections on controller and unplugged it and let it for awhile to see if it would reset. I just bought a multimeter and am learning how to use it. I will track down a wiring diagram but it might as well be in written in japanese because I won't understand it. Any suggestions as to what I should look at next?
Tks,
Rod

I believe your controller has failed. If I remember correctly that is the first reply I usually see when someone has reported similar issues. But please wait for more replies before writing a check.

I would first check the 3amp fuse in the harness that's on the back driver side upright support underneath the seat. If not that, jump out the solenoid and see if it not that. If it isn't that then check to make sure you have power to the key switch and back to the controller. There is a splice connection that yamaha did on their harness that can get corroded and makes the whole cart not move.
