Alternator: now this was a breakthrough!! Before the alternator was the dynamo-machine. A DC generator who wasn't that bad, but had a lot of glitches, the regulator system was complicated, it was large and in some cars highly unreliable. Then came the alternator. It was brilliantly constructed, highly dependable, half the size of the dynamo and very easy to repair. The output that it gave was much more stable and consistent thus allowing more appliances to be put in the car.
Use a multi-meter to make sure that the motor is getting the correct voltage. Attach the probes of your multi-meter to the motor’s plug and toggle the switch up and down. Make note of the voltage in both directions. Your owner’s manual should list the specific voltage required. Ensure that the window moves freely during this test. There should be no slow spots or blockages. Unplug the motor. If you the motor is getting the proper voltage but not functioning properly, you likely need to replace it. Start by unplugging the wiring connectors from the motor.
The term of auto electrical repairs refers to the whole range of restorative and maintenance procedures carried out on a vehicle's electrical system. This is the system that is responsible for among other things, the car's lighting system, the car's automatic starting, the car's audio systems and so much more. As long as the specific parts or systems causing problems can be easily identified, such electrical repairs tend to be quite easy. The real headache however occurs when the faulty parts or systems can't be easily identified; so that the whole process has to be carried out by 'trial and error.'
Replacing a Faulty Switch: Locate the window switch panel. This is the button used to operate your window. It is almost always on the door, however, they are rarely found on the center console. Remove the window switch panel. Be careful not to scratch up the door panel while removing the window switch, as it often requires prying. Using a shop rag or piece of cardboard under your prying tool can help. Unplug the wiring connectors from the switch. You will need to test these connectors to make sure that they are providing the appropriate 12 volts to your switch.
