Diagnostic Aids

Fig. 195 "Weather Pack" Connector Terminal Replacement:

Due to low system voltages, special weather resistant connectors and wiring harnesses are used throughout the C-3 system. If wiring and/or connectors are diagnosed as defective, special repair procedures must be followed. Damaged molded connectors must be replaced by splicing a new connector into the harness. Damaged ``Weather Pack'' connectors can be repaired as shown, Fig. 195. If ``Weather Pack'' terminals are damaged or bent, or if connector housings cause terminal misalignment, they must be replaced.
Terminals should only be removed from ``Weather Pack'' connectors using tool No. J-28742 or equivalent. Use of any other type tool may deform the terminal or housing, and unlike standard blade-type terminals, these terminals cannot be straightened.

Fig. 196 Typical C-3 System Wiring Harness Repair:

If damaged or defective, engine compartment wiring harness must be replaced with an exact replacement. However, single wires can be repaired as shown, Fig. 196. Use only wire of the proper gauge with high temperature insulation. To ensure the best possible bond at wire splices, all connections must be soldered.
Before repairing or replacing any C-3 system component diagnosed as defective, check wiring harness connections as follows:
1. Disconnect electrical connectors from component and check for bent, broken or dirty terminals and mating tabs.
2. Clean, straighten or replace terminals and connectors as needed.
3. Reconnect electrical connector and repeat test procedure.
