Navitas-converted Club Car Precedent Stops/Lurches
Last spring I converted my 2006 Precedent to lithium and a Navitas AC drive.
Overall the conversion has been fantastic. The last couple of weeks, however, my cart has been locking up then lunging. It is most common at slow speeds. Often when I let off the pedal a bit. Tonight it completely stopped on the way home. Toggling the tow/run switch got it going again. I suspect either the tow/run circuit or the Navitas regenerative braking. Adjusting the controls does not seem to have any effect. I checked the iPhone Navitas app and it does not show anything useful to diagnosing the problem. What suggestions do you have? Thanks, Evan |

I'll call the dealer and maybe Navitas tomorrow. Maybe there is a way they can interpret diagnostics. |

Talked to Navitas. They determined the problem was the controller to motor harness. A replacement will be sent Tuesday.

IIRC, the pins in the molex were set back a ways inside the plastic - take a look at yours when you pull it out and compare to the new one they send you. I'd be curious to see if there is a difference in that regard. |

I did get the current error Friday when I was diagnosing it. I also got 4 chirps followed by 5 chirps. The Navitas tech seemed quite sure he had the problem nailed. I have not torn into it yet to see if there's an obvious issue with the harness.
