2008 rxv won't go forward or reverse

[Garrett2177]

I just got finished taking a short ride with my kids and about 15 minutes later tried to take it out again. The cart won't move. Makes a clicking noise and reverse noise but does not move. If I put in tow/maintenance mode and put in neutral it moves. Any help is appreciated

Can you measure your battery pack voltage? If it’s too low the cart stalls. Believe it or not, a healthy battery pack voltage is around 50 volts.

My batteries are 3 days old

Hmmm...

Any 12 volt accessories running off a single battery vs. through a voltage reducer?

Battery age has nothing to do with battery pack voltage or the controllers calculations of SOC (State of Charge). Brand new batteries can be undercharged! Read this...

A SOC guage does not read the pack voltage itself to determine the SOC reading, it only displays what the controller CALCULATES the SOC to be. So if the controller calculates the SOC to be low, no matter what the actual voltage reads, it will not operate. When an RXV is run way below 50%, it can lose track of SOC. To reset it, flip the run/tow switch to tow, key off. and disconnect all of the wires from the battery pack positive terminal, and leave it disconnected for a few hours. Keeping it in in tow mode with the key off, reconnect the wires and secure them tightly. Flip it back to run mode, turn on the key in neutral for about 5 seconds and turn it back off. Plug in the charger and let it charge fully. After the charger shuts off, wait several hours and then start another charge cycle. After that completes, turn on the key in neutral and see if your SOC guage reads normal once again. If so, go ahead and try driving it. Never allowing it to go below 50% again is best.

This part pertains to you more...

When you install new batteries, they must be broken in, and the controller is going to have difficulty with trying to calculate SOC with new batteries while they are breaking in. So any time you change batteries in the future, you may need to repeat this SOC guage "reset" one or more times.

You are not really resetting the SOC Guage, you are resetting the controllers SOC calculations. This is the easiest thing to do, before getting into more in-depth testing for problems. The most common RXV issues are battery related, and motor brake related. Early model RXVs (2008 - 2012) should NEVER have an aftermarket or HD (Heavy Duty) motor brake installed. That can cause all sorts of intermittent issues, and eventual failure of the controller. The HD motor brakes draws too much current and will eventually burn out the motor brake control circuit. Only use an OEM motor brake. Again, this is provided for informational purposes. I'm not saying you've done this. But if you have, it will cause issues.

Thanks for the info. I will try this today
