Question about Ford Tempo

1 Answer

HI My charging lite on my 1986 Ford Tempo LX will not go off. I found a frayed belt in between the alternator and engine. Could this be the issue or should I look at the alternator/voltage regulator. The battery is brand new. Thank you

1986 Ford Tempo LX wipers won't shut off, all the other speeds work fine.


You must have a bad wiper switch. By any chaqnce, is the headlight switch and wiper switch on the same stalk? The bad alternator may have shorted out the switch or it may have caused some wires to get hot, melted the insulation, and the heasdlight feed wire is passing current to the wipers-this would be hard to find, but look at the connector for the wiper switch, and check the wires both before and after the connector as far as you can to look for a wiring problem. I hope the new wiper switch fixes it.
Good luck.

This TSB is being republished in its entirety to update the Service Procedure outlined in the Action.
ISSUE:
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:

Removing a 1987 ford tempo power steering pump


I believe you have 2 beltson this engine. One for the alternator, a short skinny one. Loosening the alternator bolts and pulling the alternator towards the front of the car, and then tightening the adjusting bolt.
The other belt runs the power steering, a/c compressor and water pump. I think it has an idler pulley with a jack screw adjusting screw. loosen the screw to releive belt tension. good luck
