Good To Know

Q: How do I know if my voltage regulator has failed? A: A battery that keeps draining, dim or flickering lights, or a battery that boils over from overcharging all indicate regulator trouble. Test charging voltage with a multimeter before ordering.

Q: Can I install this voltage regulator myself? A: Yes, replacement is typically a bolt-on job with basic hand tools. Disconnect the battery first and follow the service manual wiring diagram during installation.
