05 precedent with leaf lithium stopped running

[sporty2k]

Hey Everyone,

Running great since the conversion about 7 months ago all of a sudden it has stopped working.

Cart
05 Precedent
400Amp controller Curtis Sepex
Heavy duty solenoid
Leaf Lithium Battery - NO BMS

Status
Run/tow switch set to run
Key switched on - dash powered
FNR in reverse
Battery shows charge at 55.1 volts

Symptoms
Cart does not move
no reverse buzzer - replaced with new switch - no buzzer sound - replaced back with original switch no buzzer sound
Can hear pedal click with depression of accelerator but no solenoid click

Troubleshooting attempts
OBC was not properly disabled so I've properly disabled it by jumping same gauge blue and white wire on the harness side of OBC

At his point I'm unclear what the problem could be. I'm wondering if I've fried my controller?

ANy help or suggestions appreciated!
