Got a 1994 Mack ch-613. Truck runs fine but will die frequently and will not start back. Im sure It's an electrical problem. It's giving me two codes a 6-2 and 6-3. I've checked all the plugs. Looked all over for a broke wire. About to pull my hair out. Any help would be appreciated. It's even been to a Mack dealer and they can't fix it.
