Went to PM a RC3000. Took the covers off and blew the equipment and motors out. Afterwards its throwing this code only when trying to get the equipment to move. The equipment is really slow moving. Checked the forward and reverse contactor tips for wear and did end up replacing one of them due to tips being worn. But still ended up with the same result. Ohm the traction motors out and they tested fine. I'm at a lose it ran fine until it gotten blown out. Any suggestions?
