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.

Can you have too big of an alternator?

No, you can not have a alternator to big. These alternators were designed for later model GM vehicles to handle the power needs with lower rpm we now see with over drive transmissions.

Can an alternator be upgraded?

In a lot of cases, you can upgrade to an aftermarket radio without worrying too much about installing a high output alternator. However, there are cases where you’ll clearly end up piling on more than the factory alternator can handle.

What size alternator do I need for 3000 watt amp?

250A
3000 watt / 12V is equal to 250A. A 250A alternator is needed to keep up with it. Since your engine would have to work just as hard as any portable 3KW generator to keep up with the amplifier, you would need a large fuel tank.

How do you rebuild an alternator?

Follow these steps as you learn how to rebuild an alternator. Steps. Disconnect the battery leads. Remove the air cleaner for easier to access the alternator. Mark the placement of the electrical leads before removing them. Disconnect the electrical leads. Remove the vehicle’s serpentine belt .

What is a high amp alternator?

A high-amp alternator’s output can be negated by a charging wire or cable that is too small to handle it. The more amperage an alternator produces, the bigger the cable required.

What is the output voltage of an alternator?

Ideal Voltage Output. Ideally, the GM alternator should be putting out anywhere between 13.5 and 14.5 volts. A voltage regulator helps regulate the voltage that an alternator provides. If the voltage dips below the optimal range, then the regulator kicks in to get the alternator to make more voltage.

What is an alternator coil?

The alternator field coil is the magnetic coil inside the alternator that controls its output current. The more current passed through the field coil, the more current the alternator produces.
