Part I Service Procedure

COLD ADVANCE DIODE:

Correction A

Reverse the wire terminal leads in the engine harness connector to the altitude advance diode as follows:

1. Open hood.

2. Remove the altitude advance diode located on the engine wiring harness above the master cylinder. Refer to Figure 1.
3. With a small screwdriver, unlock the wire terminals from the engine wiring harness connector and remove the terminals from the connector.

4. Reverse the position of the two terminals and reinstall into the connector.

5. Reinstall the diode assembly on the engine wiring harness.

6. Correction B must also be performed.

Correction B

Reverse the direction of the cold advance diode in the engine wiring harness. Locate the cold advance diode (spliced into the engine wiring harness) as follows:

COLD ADVANCE DIODE:

1. Open hood and locate the altitude advance diode located above the master cylinder. Refer to Figure 1.

2. Follow the light green/black wires from the altitude advance diode into the wiring harness conduit (approximately 14") to the taped splice. Do not remove tape from splice.

3. At this point you should see silver/gray tape which covers the cold advance diode. The diode has a dark green wire and light green wire with a black tracer leading to it.

4. Cut the dark green and light green wires so about 1" of the green wire is left on each side of the cold advance diode leads.

5. The cold advance diode should be soldered back into the harness with its leads reversed. That is; the light green wire on the diode should be soldered to the dark green wiring harness lead and the dark green diode lead should be soldered to the light green harness lead. This procedure can also be performed with electrical wire crimp on slices, if available.

6. Using electrical tape, tape over both solder or crimp joints to insulate them.

7. Carefully tuck the diode and wires back into the engine wiring harness conduit.
