2011 RXV Jumps then nothing???
A rat got into my 2011 RXV and chewed up a few wires several weeks back at our hunting camp. I crimp everything back together and cart has been running as normal until this weekend. Now when I turn the cart on (any position) it clicks as normal then jumps in reverse a few inches and then stops and won't move. Doesn't matter if R/N/F it does the same thing. Go pedal doesn't work. Brakes do hold. I can turn key off and put in tow, turn back on to N and cart will move freely until brake pedal is pressed, then it locks up as normal.
I ran through every wire under the dash and around controller and checked my crimps and all looks good. A little searching around has me thinking the brake needs replacing. Maybe a throttle/pedal sensor? Hard topic to search. Anyone have thoughts or recommendations on this? THANKS! Sent from my Pixel 2 using Tapatalk |

Re: 2011 RXV Jumps then nothing???
Ok, that would pass the powerup test. So it looks like the Motor Brake Driver FET is staying turned on instead of switching on/off in response to the controller. I have replaced those FETs on the Curtis controllers. With a 2011, it came with a Danaher controller. Unless it's already been upgraded to the Curtis, it may be time...
The Danaher controller cannot operate a HD Motor Brake because they draw too much current and will start acting flaky as the FET overheats, then they short out. If you or someone else has changed it out for an HD Motor Brake, that could have been the start of this problem... Bob |

Hmm. I did put a new brake in it last year but I don't think it was an HD brake.
I'm still wondering how it was fine when I parked it last Saturday with a full charge and this Saturday it does this when I go to use it. Sent from my Pixel 2 using Tapatalk |

The controller should be able to tell us the sequence of events that led up to this issue. |

By the way, what does FET stand for?

Field effect transistor , it's basically a electronic switch with no moving parts.
