Subject: FUSIBLE LINK AT THE BATTERY POSITIVE TERMINAL BECOMES BRITTLE AND DISCOLORED ON 1988-89 LEMANS (REPLACE LINK)

Models

Affected: 1988-89 LEMANS
Cause: Fusible link can become warm because of improperly torqued connection at battery.

Correction: Replace fusible link with a 6 inch long, 3 sq.mm link*. Solder both ends, at the 10 mm feed wire and at the terminal at the battery. Torque battery positive cable to 4.8 N-m.

*Note: The battery fusible link size has been changed
from 2 sq.mm to 3 sq.mm.

The generator output fusible link at the starter solenoid has also been changed from 1 sq.mm to 2 sq.mm.

If either of these fusible links need to be replaced, use the new size. Do not tape over fusible link or insert into a conduit.
