My EV has been great, but has run into an issue that has me stumped (which ain't hard...). We were riding one evening, rolled over a small log and heard a "whack!" on the bottom of the EV. I don't know if the whack had anything to do with it, maybe knocking something loose, or just coincidence. Suddenly, my EV would only roll forward very slowly, with a very faint, regular ticking sound. After towing it back to the barn, I looked everywhere and could see no signs of damage. So I did the usual, checked and filled all the battery cells (all good), removed and cleaned all the battery wires (replaced one that had corroded through), replaced the MPC (long overdue- it was pretty fried) and charged her back up. Everything comes on like normal, but still creeps forward (and backward) very slowly. Surely there's an answer?
My Polaris Rangers are 2011 and came from a salt mine. The brakes are badly corroded and are 'stuck on' most of the time when I go to move it (my range is pretty bad because of that)
For the longest time I thought the controller was bad, since with 'Medium' speed, it would only 'creep' forward and reverse. Once I got the 12V DC/DC converter working, and I could select High and Low, it worked much better. But I had checked the throttle signals, 12V signals, connectors, and a bunch of other stuff before I figured that out.
So .. can you push the Ranger forward and reverse with the steering straight, on level ground?
And have you tried High, Medium and Low speeds?
If the 'Clunk' was a failure of some part of the brakes, and the brakes are holding the ranger back ... perhaps that could explain your slow movement. It's a bit thin, but I think it's possible.
