I have a YDRE 2014 I think. the controller a Moric Model JW2-H6510-01 isn't passing pin 3 the solenoid ground to the solenoid, I was able to get the cart to work by bypassing that pin with a ground to the motor so the solenoid would kick in. does that mean the MCU is shot or can it be repaired? with the alternate ground the solenoid remains engaged so I have to set the tow-run switch to tow so it doesn't drain the batteries. is it safe to run it like this? the wire from the controller to the solenoid is good.
