How to Choose the Right Powermaster Alternator for Your Vehicle

Not having enough amps to properly feed your vehicle’s electrical accessories can DOA a typical OEM electrical system. Amperage is defined as the maximum amount of electricity an alternator is capable of producing. If your vehicle’s electrical load exceeds the amperage capacity of your alternator, you’re asking for trouble. The extra amperage draw created by a high-power audio system, race electronics, lighting, etc. can cause a stock electrical system to literally melt from the inside out.

Powermaster has a pretty simple method for choosing the right-size alternator for your vehicle:
• Make a list of your vehicle’s electrical components/accessories
• Determine the amperage draw for each and add together to determine the total draw/load
• Select an alternator that delivers more amperage at idle than the total system draw

This OnAllCylinders article gets into more detail on the hows and whys of alternator selection.

Once you know how much alternator you need, Summit Racing has a Powermaster alternator to do the job, including these:

Street Alternators are ideal for street-driven vehicles. They are available in capacities ranging from 70 amps to a whopping 240 amps. Most can be set up for one-wire operation and come with a pulley for a serpentine or V-belt accessory drive system depending on the application. You can even select the finish—you have a choice of natural, polished, chrome, and black.

High-Amp Alternators have the capacity to handle modern electrical systems with accessories like winches, aftermarket lighting, and air suspension. The alternators feature hand-wound, custom-designed stators; heavy-duty regulators and rectifiers; and a gold-plated battery post for better electrical connections.

XS Volt Alternators have a powerful, digitally-controlled regulating system that can handle voltage-sensitive ignition systems and lithium batteries. The alternators can adjust output in milliseconds, and the voltage can be adjusted between 13.5 and 18.5 volts to work with 12- or 16-volt electrical systems. Other features include short circuit and loss-of-ground protection, a sealed and vibration-resistant housing, and one-wire operation.

Summit Racing also carries Powermaster PowerGEN alternators that offer modern performance in a classic generator-style case; Smooth-Look alternators with sharp lines and edges smoothed and blended for a custom look; diesel and marine alternators; and alternator kits for racing.
