Checking Generator Connections

CAUTION: The engine must not be running when multiplugs are connected or disconnected.

Check that the main B+ terminal is clean and tight.

Check that the IG terminal is clean and making good contact; if this connection is faulty, the generator will never function correctly.

Disconnect the multi-plug at the rear of the generator With the engine not running and with the ignition switched on, use a DMM to check for battery voltage between the centre pin on the multi-plug connector and a good vehicle ground. If the measured voltage is correct, switch off the ignition and reconnect the multi-plug.

Multiplug Connector:

If no voltage or low voltage is indicated, check for continuity of the harness between the multi-plug and Fuse 5 (10 A) in the Engine Compartment Fusebox - Left Hand Side. Repair any damage to the harness if necessary. It should be noted that if Fuse 5 has blown, the starter motor will not operate and the Engine Control Module will not receive an ignition supply. Consequently, the engine will not start, even with a slave battery.

Start the engine and test for correct charge or voltage level; check as described previously. If not charging and the generator is being driven ie. no belt slipping - renew the generator.
