ALTERNATOR OPERATION TEST

Check 5530AB

Start the engine

Disconnect the battery negative terminal

Activate side lights, low beams, high beams, hazard lights, rear fog lamps, windscreen wiper, passenger compartment ventilation and any other in-car electrical device.

The aim of activating all these devices is to see whether the car keeps running without any current supply from the battery.

Wait a few seconds to see whether the vehicle keeps running.

If the engine stalls, this means that the alternator is not operating correctly and the electrical system is not able to keep the various electrical devices in operation without any current contribution from the battery.
