Why does my alternator keep Blowing my Fuse?
However, these fuses can blow due to a power surge or simply from old age. Once that happens, the alternator will no longer charge the battery. Not all vehicles have these fuses, so you will have to check your owner’s manual to see if your car has them.
Can a bad car battery cause an alternator to not charge?
In theory a car can run only with the alternator charge, but this can cause heavy voltage spikes and other strange symptoms so this means that a bad car battery can cause an alternator to not charge also. Cars are increasingly coming with modern electronics.
What should I do if my alternator is not working?
The solution is to check your car’s manual for the particular fuse that controls the alternator and replace it. In some cars, you might also find another small fuse to the alternator’s control—usually a 15A to 20A fuse. An alternator does usually has 3 or 4 wires to it to function properly.
What causes an alternator to go over base voltage?
If you are getting more than 2 volts above base voltage, most likely your alternator is over-charging the battery or the battery is faulty. Other potential problems are a faulty voltage regulator or a problem in the charging system wiring.
