Good To Know

Q: What can happen if a marine voltage regulator fails? A: A failed regulator can either undercharge the battery (leaving it dead) or overcharge it, which can cause the battery to swell and damage connected electronics.

Q: Is this regulator sealed against water? A: Yes, it features potted electronic components to prevent water intrusion and resist marine corrosion.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
