REFERENCE INFORMATION BAD CONNFCTIONS ARF MF MOST COMMON PRO61 FM ! Sometimes just disconnecting, cleaning, and reconnecting will solve a problem. BE THOROUGH ! The time you save may be your own. Refer to the functional flow schematic and check the following: 1. BAlTERY - make sure all connections are clean and tight. This includes the interconnect cables, clamps, shunt, power stud, and the slave connector. Also check wires 6A and 7A under vehicle where they enter shunt. 2. STARTER - check the high current (heavy gauge) wire at the starter. Don’t just check for voltage; a loose connection will have voltage but can’t carry much current. There is a ring inside the battery fill plugs. The water level should be at the ring.
