Question about 1986 Ford Tempo
Left work and on the way home the light came on and it will not go off.
Replaced the battery in late summer. Can it be the alternator or voltage regulator if this car has one???

This TSB is being republished in its entirety to update the Service Procedure outlined in the Action.
When a generator fails, there are a few failure modes that may cause heat to be produced at the wiring harness-to-generator connector. This excess heat may damage the female terminals on the wiring harness, resulting in increased resistance. The increased resistance produces more heat. When the generator is replaced, the resistance produced by a damaged connector may damage the new generator and could result in a repeat repair, including installation of another generator. High resistance (caused by a damaged connector) will not go away until the damaged connector is replaced. ACTION:
Visually inspect the harness-to-generator connector for damage (heat, corrosion, distortion and cracking) before installing a new generator. Install the Generator Wiring Harness Connector Kit (E5AZ-14305-AA) if the harness-to-generator connector is damaged. The Generator Wiring Harness Connector Kit (E5AZ-14305-AA) contains the following:
