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.
