I have a Belarus 570 tractor that I have a question about the wiring. It has 2 batteries in the back making 24 volts. Every wire that I have checked under the dash has 24 volts. I've been working on getting all lights and a/c and wipers working and have a question. Is everything supposed to run on 24v? The wipers seem to be spinning extremely fast and also I have blown 2 bulbs so far. Thanks for the help.
