I recently put all new batteries in my '97 club car. I bought it used last year and it ran great up until a couple of weeks ago when I had a battery short out, so I replaced all of them. When I went to charge my new batteries after running them down, they would not charge (the charger meter stayed at zero when I plugged it in). After going through the forums trying to figure out what the problem was, I decided to try and reset the OBC by following the instructions in the resources forum. However, my cart does not have a "tow/run" switch. Does this affect how I reset the OBC?
