Condition:

On some 1988-90 B cars the battery may run down or the generator may have high or no output. Replacing the above components will not correct the condition.

Replace the fusible link following the directions in the Service Manual, Section 8A. Coat the new fusible link with a sealer or heat-shrink tubing, to avoid any future corrosion.

Warranty Information:

Use existing labor operation.
