Yamaha G22E does not move

[cgtech]

The front left most terminal (main negative of the pack).

Ok, I will recheck tomorrow.

[Jhcorley]

With the switch on RUN I have 51V on both back tabs of the switch and with the switch on TOW I have 1.5V on the top back tab and 51V on the bottom back tab.

[cgtech]

Well, then I guess you can't drive it in tow... What about in run? Still 17v?

[Jhcorley]

I had the NEG probe on the 2nd batteries in the series so that why I was getting 17V.

[Jhcorley]

It will not run in either TOW or RUN modes.

[Jhcorley]

Any other thoughts? I have 51V in RUN at the switch.

If you checked controller pins 1 & 2, but still nothing, still sounds like bad controller. Put your meter Probes on small solenoid wires, while watching meter, flip tow/run to "run". Should power up for a few seconds then turn off. If pins 1&2 are hot but no power at solenoid small wires, Bad Controller. I know no one wants to hear bad controller, but if voltages check out & controller doesn't do what it's supposed to, controller is likely bad.

Very new here but have some mechanical knowledge so the help is appreciated!

Thanks

Was it a bad controller?

It's when the silver box (controller) with
wires from the batts to the motor
& everything is sending the correct volts & signals to it
But the cart don't "go"

A bad controller
don't send battery volts & amps to the motor
