This will replace your early Prestolite Marine Alternator.
Your original Voltage regulator will no longer be needed or used. Simply connect the main alternator feed or output wire and ground wire; that’s it! Then secure and tape off the loose regulator field wire end. Your gauges and electronics will still function as before.
Please be sure Battery is fully charged and all connections are clean and tight.
This is a very common problem in marine electrical systems.
Corrosion, or bad connections will cause low voltage to the electrical components. Low voltage causes high heat or resistance and will destroy electrical devices.
