We are cruising from Pender Harbour to Desolation Sound. About 2 hours into our journey, the gauges (Tach, oil and temperature) shut down. The amps in/out on the bank had gone negative, indicating no output from the alternator (Amptech125). The Voltage regulator is a Balmar MC612. With a clamp meter, I have verified there is no output from the alternator. The clamp meter confirms output to and from the house bank. I have selected the Blueseas ACR between the House and Start banks to off. The Magnum charger panel provides amps in/out to the house bank and voltages.
Current situation: solar panels are approximately maintaining the house loads and the house bank is at 91% SOC. I have a northern lights 5 kw genny.
I have a mechanical oil gauge on the engine indicating normal pressure. Digital laser thermometer indicates normal temperature. Digital tachometer indicates cruising RPM.
I suspect the Amptech alternator is the problem. I have a new identical unit, which I intend to install in place once I’m at anchor. However, what is the likelihood that the MC 612 is the issue and how would I diagnose that situation?
Any other advice/recommendations most appreciated.
