The Balmar MC-618-H premium multi-stage voltage regulator gives the ultimate in charging safety and control, a genuine step up from the basic single-stage regulator most stock alternators ship with.
Intelligent multi-stage regulation adjusts charging behavior as the battery fills rather than applying one flat voltage throughout, and a digital numeric LED display shows exactly what the regulator is doing at any moment. Epoxy-encapsulated circuitry protects the electronics from the damp, vibration-heavy environment inside an engine compartment.
It works with 12-volt systems and P-type externally regulated alternators, can drive twin alternator installations, includes dash and auxiliary lamp terminals plus a small engine mode, and ships with a magnetic programming tool and the wiring harness needed for a complete install.
