Generator — troubleshooting (Opel Ascona C)

Because diagnostics of a generator require specialized knowledge and equipment, it is recommended that the generator be thoroughly checked by an auto electrician who has the necessary equipment to perform this work. Given the above, the information provided is limited to checking and replacing brushes. If the generator is not charging the system, you can perform the following checks before calling a professional for advice:

• a) Check the alternator belt tension as described in Chapter 2;
• b) Check the condition of the battery and its connections (see Section 3);
• c) Check the condition of all electrical wires and connections for reliability and correctness.
