Inspect for any signs of corrosion due to water incursion. If
hard-wired, ensure that all the fork connectors are properly
secured to the terminal. Verify all wires are fully crimped and
do not pull loose.

A) Inspect the wire terminations for loose connections,
corrosion or wire strands.
B) Inspect the Harness’s pins and sockets for bent pins,
torn boots or any signs of corrosion.
The first step in troubleshooting a problem with the Propulsion
System is to determine if the problem is with the Control System or
something external to the System. In all cases a Control System
malfunction will alert the operator of the potential problem. This
is accomplished through the audible tone emitted at all Remote Sta-
tions. When an audible tone is emitted, it will be accompanied by
an Error Message at the Processor. Also, in many cases, the Con-
trol System will alert the operator to a problem external to the Con-
trol System.
The following are examples of components both internal and exter-
nal to the Control System which could be a source of trouble:
The following pages should give you a good guideline for making
this determination. There is no need to troubleshoot the system to
any point further than one of the main components listed above. If
the fault is found to be with a Control System component, that
component is simply replaced. If the fault is found to be with one
of the external components, replace or repair the defective compo-
nent or contact a qualified mechanic.
