Correction





Replace the voltage regulator attaching screw with the screw and washer from the service kit following the procedure outlined.

1. Disconnect the battery cable.

2. Remove the wiper module cover (U-Van).

3. Remove the voltage regulator ground screw (1). (This is the recessed screw located 1/3 of the way from the large battery cable attachment to the generator harness.) Use a stubby # 2 Phillips screwdriver to break it loose and then loosen the screw with a small pocket screwdriver. The screw may hang up on the plastic cover on the rear of the generator. If this happens, use a pocket screwdriver inserted between the screw and the cover. The screw will pop out when a little sideways pressure is applied.

4. Install the screw and washer from the kit through the voltage regulator and into the generator case.

5. Tighten the screw securely.

6. Replace the wiper module cover.

7. Reconnect the battery cable.

Tighten

Tighten the cable to 15 N.m (11 lb ft).
