Will a high output alternator hurt my car?

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. … So high-output alternators will not harm your components or charging system, no matter how high you go with the amps.

How big of an alternator do I need for 3000 watts?

3000 watts / 12V = 250A. You’d need a 250A alternator to keep up with it. You’d also need a much fuel tank, since your engine would have to work just as hard as any portable 3KW generator to keep up with the amp.

Do alternators charge at idle?

Yes, the alternator does charge the battery while the car is idling – regardless of the load on the battery. However, if your electrical use load (radio, lights, fan, etc) exceeds the amount of charge the battery is receiving from the alternator, you will end up with a discharged battery at some point.

What is the highest output alternator?

The highest 12 volt produced by Prestolite Leece-Neville is the J-180 mount 4890JB and Pad Mount 4962PA both of which put out 320 amps. When it comes to 24 volt alternators there is one manufacturers that really stands out – C.E. Niehoff has their 500 Amp C-803D.

How do high output alternators work?

A high output alternator is generally used to increase the amperage within the electrical system. … The amps stored in a battery’s reserve capacity then provide the amps when electrical load exceeds the charging system output. However, this could affect the power of the battery negatively and put pressure on the battery.

How many amps does a alternator put out at idle?

50 ampsAt idle speeds of about 650 RPM it can only produce 50 amps or so. This is why when you have a loose alternator belt or a defective belt tensioner, you only hear the squeal when you hit the gas initially after you start the engine, not with the engine idling.

Can a sound system mess up an alternator?

If you’re hearing a grinding sound in your car, this could indicate that the alternator is going bad. The grinding sound may be caused by a worn-out bearing. Your car can also make a whining sound when the voltage regulator is sending signals to the alternator to charge more than is necessary.

What would cause my alternator to overcharge?

An overcharging automotive alternator can be the fault of the voltage regulator, an accidental electrical path causing the field windings to be powered independently of the regulator (bypassed) or the sense circuit to the regulator not properly providing the correct battery voltage to the regulator.

How many watts does a 200 amp alternator produce?

2880 wattsA large alternator can be 200 amps or more. 14.4 volts x 200 amps = 2880 watts.
