I’ve upgraded my EZGO RXV from a Danaher to a Navitas controller, and now I’m stuck with the brakes locked! It’s driving me nuts because I can’t use my cart at all. Has anyone else been through this and figured out a solution?
Response
I faced a similar issue with my 2010 RXV. It turned out the brake switch wasn’t set correctly. Adjusting it to the ON position, which powers the emergency brake, solved the problem for me.
