What causes alternator to burn out?
A battery that won’t charge properly puts an excessive strain on the alternator that it was never designed to handle and will quickly cause it to fail. A good battery should never drop below 10 volts when cranking, assuming the starter is in good shape and not pulling excessive current.
What would cause an alternator to keep going bad?
There are a few issues that could make the alternator go bad, such as jump-starting the car the wrong way or installing an accessory that overloads it. Leaking fluid in the alternator or a tight belt can also cause damage to the alternator bearings, causing premature wearing.

How do you make an alternator put out more amps?
If you don’t need more amp output but want more amps available at idle and low engine rpm, the easy upgrade is swapping the factory pulley for a smaller-diameter “power” pulley. Installing a smaller-diameter pulley on the alternator shaft speeds up the rpm of the armature so more amps are produced at that engine rpm.
Will a capacitor help my alternator?
It really depends on how much power your audio system requires and how much your alternator has left after powering everything in the car. Many people can get away with a capacitor and some need to upgrade the alternator. The capacitor really helps with those brief moments where the amps pull lots of power.
Can an alternator be too powerful?
How Much is Too Much? You can never have too much amperage when it comes to alternators; therefore, you never have to worry about choosing an alternator with too high of a rated output. Here’s why: Amperage is basically the amount of electrical current your alternator can supply.
