We recently bought a used 2011 Ranger EV side by side. My problem is that after a small amount of driving, I turned off the switch to do something when I got back on to go again the wrench shows up and then it won’t go forward or back. It has done this to us twice. After a little while it comes out of it and it begins to work normal again. I have cleaned the battery terminals, checked for loose connections, etc.-can’t find the source of the problem. Has anyone had this happen to their EV? HELP!
