2014 rxv motor brake not unlocking.
 

Took my cart for a few miles ride the other night, mostly road, also thru a small section of a field. When i got home i stopped in my driveway and turned the key off. Opened my garage and tried pulling it in. The cart womt move. When i turn the key i hear the clicks and it seems as though the motor break disengages momentarily. But when i push the gas pedal, nothing happens. When i cross the #3 and #1 plugs under the run/tow plastic cover, that does disengage the motor brake and i was able to push into the garage. Pack voltage os 100% at 51v. The wire leading to the motor break is getting 47.8 volts to it when i tested. Thats all ive done thus far.
Any of the experts on here have any ideas? Hoping i didnt blow my controller (curtis)

Mine did something very similar. Was driving it with no issues and nothing out of the ordinary conditions wise. Parked it by camper to make lunch and it wouldn't move again. Figured it was brake, so off to dealer to get one. Swapped it and same. Had also read on here that the solenoid could cause similar issues, so I purchased one of those while at dealer also. Swapped it out and cart started working again, so that was my issue. Good thing is I now have an extra motor brake (that I paid full retail for,Lol) in the tool box.

Bump

I'm really hoping that those 23" tires didn't overheat your 235A controller and cause it to fail. Usually when that happens though, it dies during operation, not after stopping. It does sound like a motor brake issue.

Bob. I dont think its the controller, and for the same reason. Because it stopped working after i stopped operation. Jeff has sent me the diagnosis pdf and ive bebeen soing the tests

Motor brake cable shows 48v

Notor brake continuity is 26 ohms

Solenoid large positive input is same as battery pack

Solenoid lg pos output to controller only jumps to 36v then slowly goes back down? *weird cause the manual states it should be withing 1v of the input?*



Tmoro im going to check the brake and throttle pedal
tests,

This is the test that i think isnt showing the right result. When i hold the meter neg lead to batt#4 neg post, and the pos meter lead to the solonoid output to controller post, i turn the key on and it jumps to 36v, then slowly goes down

Also, whats weird is when i put it in tow mode, and turn key to nuetral, it wont roll freely, but when i cross the two plugs under the plastic cover thatd over the controller and solenoid area, the motor break will disengage

Time to replace the solenoid
