    For those disinclined to open up an alternator and tap into the field wires, the Sterling Power ProAlt-C can be an easy to install alternate solution. When looking for optimal charging performance we strongly urge that your first choice be a true external voltage regulator, but for those who have ECU controlled alternators, or engines still under warranty, the ProAlt-C is a great fit.

    The Sterling Power ProAlt C is effectve, simple and fast to install. It transforms the output of your alternator into a sophisticated multi-stage battery charger resulting in faster and more complete charging of your battery bank(s). The ProAlt C is fitted between the alternator and the battery and, unlike conventional alternator boosters, requires no modification / interference with the alternator whatsoever - therefore, bypassing any ECU or warranty restrictions. The ProAlt C optimizes the available output of the alternator and converts the output to a 4 stage battery charger similar to using an external voltage regulator.
