Ez go rxv brake locked
I am having a problem with my 2013 rxv. As with many on here, my cart will not move, my buzzer sounds when in reverse and i get clicking in both run and tow mode. It still will not move. I used the instructions on the bottom of the controller to manually disengage the braking system and it still won't move. Has anybody had this problem that could help me trouble shoot the issue. Thanks for any help...

On of the first things to check on the RXV is the battery pack voltage. Are the batteries fully charged? The RXV controllers are very finicky about proper voltage. To properly test some things, you will need a multimeter. One with a digital readout is preferred. If the brake does not disengage when you follow the Emergency Tow Mode by swapping plugs under the controller cover, then it would seem that either you do not have voltage at those connections, or the motor brake itself is bad. The first thing to check after confirming that the batteries are properly charged would be to check the blade fuses under the caps attached to the controller cover. 2013 RXVs should have 2 fuseholders there, one with 2 red wires and the other with 2 yellow wires. If either of those are blown, replace with a new fuse of the same value. If all is good at this point, it's time to test the motor brake. Unplug the 2 pin connector at the motor brake. It is located at the top of the rear end of the motor. You hold the retaining clip of the harness plug slightly away from the socket and pull upon the plug. It has a weather seal, so it will be a bit firm. Once this is done, try activating Emergency Tow Mode again and check with your meter to confirm that you have batter pack voltage at the 2 pins of that motor brake plug. If you have pack voltage there, then it's possible that the motor brake itself is faulty. You would use a low ohms range on your multimeter to check the motor brake coil by putting the meter probes in contact with the 2 pins of the motor brake socket. You should read between 25 to 28 ohms. If it is open circuit or shorted, replace the motor brake unit. You can find them listed on eBay for much less than from E-Z-GO. It's a good idea for all RXV owners to keep a known good motor brake on hand for that time that it will fail. If you have no pack voltage there, then you'll need to trace back through the Run Plug (9 pin connector under the bottom of the cupholder assembly), the Brake Switch (under the floor mat and pedal cover), and the wiring in between the battery pack and the motor brake plug itself. RXVs are notorious for having bad connections in the harness, at the places where wires are bonded together, and at the terminals of plugs and sockets. At this stage, you would probably need to obtain the wiring diagram. We can help if you need further assistance. Where are you located? Bob |

Re: Ez go rxv brake locked
I've checked the battery pack and have over 50 volts there, i've also checked the fuses. I'll check all of the connections that you mentioned and report back. Thanks for the response. Located in Arkansas.

Re: Ez go rxv brake locked
Tested the 2 pin connector for voltage and it was getting over 49 volts. I tried to test the socket for ohms and could never get a good reading. I went ahead and ordered a new motor brake today and will follow up once installed and hopefully my cart is back up and running.

Re: Ez go rxv brake locked
Finally got the time to install the brake motor today. My cart is back up and running. I didn't run it long as I didn't have a torque wrench to tighten the bolts to the right spec. I tightened them snug but didn't go any furthur. Any advice on tightening the bolts without a torque wrench is appreciated.

Re: Ez go rxv brake locked
Tighten just until the lock washers are fully compressed, not much more.
