- The window of performance for most electronic ignitions is 12 to 16 volts, with performance advantages at the higher voltage. A fully charged battery is only 12.6V, and it goes down hill from there. With a Powermaster alternator, your system voltage goes to a constant 14.9V. This assure peak performance.
Fuel pumps and other electrical devices need 12 volts at all times for maximum performance.
Consistency - Using a battery charger instead of an alternator is a variable. Running a Powermaster alternator will keep the battery fully charged and predictable.
Convenience - Sizing the alternator (amps) to the load will eliminate the need for the battery charger.
