2012 EZGO RXV Gremlin

We had a 2012 ezgo rxv come in today with the complaint it was running on the course just fine and just quit. When cart was brought it they had to do the swap red connectors to get the motor brake to unlock and putting the cart into tow and the key switch to N would unlock the brake and then immediately lock again. Immediately found a battery cable from positive of battery 4 to negative of battery 3 corroded in two. Replaced with new cable and same results.
Noticed that there was no click from the solenoid so we replaced with new. Same results. Connected handheld and checked for codes. The only code was a precharge failed code in present and history. I tried changing the speed sensor for good measure but still nothing. No click of solenoid and it doesnt even try the self test startup procedure. Not sure where to go from here. Any help is greatly appreciated.

for anyone who has this issue it ended up being the controller. Not sure why it went bad with just a wire corroding but swapped out the curtis controller and the cart is running again.

If the cable corroded, possibly something else was going wrong (too hot, water, etc.). Lack of codes is strange though. Stuff just sometimes fail. Thanks for sharing though.
