AND REPAIR (SHEET 1 OF 4)
Inspect wiring harness and relay socket assembly (10) wires for cracked
or broken insulation or broken wire strands at connection to terminal.
Repair cracked or broken insulation by applying insulation tape to area.
If broken wire strands are seen, cut wire as close to terminal as possi-
ble. Strip 1/4 inch insulation from end of wire taking care not to cut
through wire then crimp new terminal securely onto wire.
Inspect wires (1 and 8) for cracked or broken insulation or broken wire
strands at connection to terminal. Repair cracked or broken insulation by
applying insulation tape to area.
If broken wire strands are seen, re-
place wire.
Inspect relays (9) base and contacts for cracks, breaks, distortion, or
other damage. Connect multimeter between relay contacts 2 and 7 and check
for 450 to 500 ohms indication. If any of the above conditions are seen
or if multimeter does not indicate 450 to 500 ohms, replace relay.
