Find the voltage regulator-rectifier on your outboard and grab a good multimeter to test the units inner diodes.

Testing a mercury outboard voltage regulator. A three-phase regulator-rectifiers diodes take the AC signal that comes out of the engines stator-rotor assembly rectifies it and then smooths it out usually through a capacitor. If your system current draw is near the max output of the charging circuit I would think this regulator is unneccessary. Fixing a mercury outboard charging system - YouTube.

Because of where the voltage regulator is located on the outboard ignition system it endures a lot of abuse. 883072T Rectifier Voltage Regulator 6 Wire 12 Volt Compatible with Mariner Mercury Outboard 830179T 815279T 854515 815279 856748 883072-75-200HP 1987-2005 - 2346 Cylinder. The RR is checked for output voltage with the motor running at a fast idle when connected to a fully charged battery.

In a C115 the tachometer signal does not come through or from the RR. I also believe that the voltage regulator under the cowling may have overheated. The rectifier youll find most commonly on an outboard is a bridge rectifier and this is the circuit diagram for one of those down here which well go through in a minute so the simplest rectifier you can have is just a single diode that only allows current to flow in one direction so instead of alternating youre simply allowing only go in one direction what this gives you though is half wave rectification.

The one I found is diamond shaped and has studs rather then pig tails. The voltage regulator is supposed to shunt excess to ground. Mercury Rectifier Troubleshooting.

The test involves the use of a multimeter. If no or substandard voltage output then checked the lighting coil for proper input to the RR. To be able to make sure the electrical circuit is constructed correctly Mercury Outboard Rectifier Wiring Diagram is necessary.

How can this diagram assist with circuit building. As speed increases with any alternator the voltage output increases proportionately as does the frequency. The rectifier can remain in place but.
