Intermitant motors should be replaced. From experience, relays and transformers rarely go out. It is usually the motor that burns out and it usually does so quickly when at life's end. Take the time to check all of your wire connections-hours can be spent diagnosing a vacuum only to find out it was a bad connection.ntermitant motors should be replaced.

If it cranks with a loud turnover noise and the car just doesn't start it could be another problem. You also need to remember that the alternator is the equipment that charges your battery. If your alternator is bad the battery will just drain like a flashlight battery until it is dead.The alternator keeps your battery recharged as your car uses it while the engine is running. Bad diodes in the alternator can cause the battery to go dead when the car is off.   The diode bridge (six diodes) is directly connected to the battery, and is used t â¦ o convert three phase delta AC from the alternator's stator to DC for the battery.
