Will the installation of a higher amperage alternator damage my vehicle or my battery(s)

No. As long as the battery(s) are in good condition, and the correctly sized alternator charge and ground cables are installed properly, nothing will be adversely effected on the vehicle

My vehicle's alternator is computer controlled. Will a higher output alternator work properly in my application?

Yes. As long as the alternator is installed properly. (some PCM controlled vehicles require specific cable routing, instructions are provided) A MechMan high output alternator will still work fine and provide more amperage than the OEM alternator.

If I install a higher output alternator, will my charging voltage be higher than stock?

That depends, depending on the part number, most MechMan alternators are designed to operate at the OEM voltage. This is done intentionally, so that the vehicle is not harmed by higher than stock charging voltage. A higher AMPERAGE alternator will keep the voltage in the vehicle closer to OEM voltage when drawing more current from the battery. If higher than OEM charging voltage is required, contact a sales rep about custom ordering your alternator with adjustable voltage.

Will a higher amperage alternator draw more horsepower from the engine or reduce my fuel economy?

That depends, the more amperage the alternator makes, the more horsepower is required to turn it. All alternators are regulated, so unless there is a heavy electrical load against the alternator, a higher amperage alternator will not provide any more drag against the engine than an OEM alternator.

Can a 2 pin GM regulator be used in External Regulator applications?

NO. The GM 2 pin is ECU controlled and differs highly from a "terminal block" or Mopar/Dodge style regulator. If you are needing external regulation, please call or email to discuss and/or setup.

Can you spin an alternator BACKWARDS?

Short answer is YES. Long answer is NO. The alternator will charge spinning backwards but the efficiency drops nearly 40% due to the internal fan not being changed. Special rotors/fans are used in these applications to restore the efficiency, cooling and durability.

My battery is COMPLETELY dead or near dead/nothing happens when I turn the key. Will my alternator recharge it?

Yes and no. Yes it will charge the battery but this should be avoided at all costs. Alternators are made to sustain the charge of the battery and cannot recharge a dead or very low battery. The alternator has one job but it’s too much of work and recharging a very low battery or dead battery is just too much for an alternator to take and will shorten its life.
