Hi. I have a 2013 Gem Car. It’s 72v.
I initially had a failed motor so the controller was throwing a code, replaced the motor and then I got a different code that was suggesting I had a controller issue so I changed the controller then got a code 40 something sent it for warranty came back now I got a code 51 I can Not get to go away. I’ve sent this back to FSIP which is the company who makes the controller and they said that they have been tested it for a whole entire day and there is nothing wrong with the controller as is so they sent it back and I still have the same problem.
New key switch.
Apparently a code 51 is suggesting that I am not getting 72 V on pin one at the controller so I unplugged the connector took the pin out and inspected it and it looks fine and I also however have 72 V when I turn on the Key so I don’t know why it’s saying code 51 - I have no voltage at the controller unless I’m missing something. I’m hoping someone has come across something before and guide me in any direction cause I’ve exhausted all my resources…
