    Why do Voltage Regulators go bad ?
    « on: October 15, 2015 - 10:14:30 PM »
    I had a 2-3 year old regulator go bad. Bad luck or did something help to push it over the edge ? 

    I have an original style 35 amp alternator and headlight relays.

    Being 2-3 years old, quality of the build may be a factor. Made in China?
    Or just bad luck.

    I believe a good ground is needed.

    Keep seeing people putting extra ground wires, frame , engine.
    Need proper size wires to regulator.

    I lost one every year on my Cummins Ram , the sealer covering the circuit board would pull away from the case & water would get in behind & short the reg , adding silicone around the edges may extend the life
