DUAL POWER TRIM SYSTEM
SERVICE MANUAL NUMBER 28
Important Information
When testing this Dual Power Trim system, take special note of the following:
•
The control box harness connectors must be disconnected and the key switch must
be OFF.
•
Make certain that the jumper lead used between terminals 3 and 5 is used only when
specified.
The following tests are listed in order of probable component failure. It is recommended,
however, that all tests be performed even if a faulty component is detected early in the
sequence. This precaution will guard against repeat failure if there is more than one failed
component.
