Alternator excitement

[bendeac]

I have exactly the same problem. If I bridge 4 and 8, the alternator excites. I have a non-standard alternator as well. There is a 68 ohm resistor wired across 4 and 8.

I have another issue I can't work out. My warning lights work, but the buzzer doesn't. Nothing wrong with it when I test it in isolation. The negative pole of the buzzer goes to 1 on the diode plate. Then a wire goes from 1 to pin 2 on the loom connector. From there it goes nowhere. Does it really go nowhere, and if it does, why would there be a wire running off 1 on the diode plate?

Welcome to the forum. You'd be better off starting a new thread and give as much information about your problem as possible, include information about your boat, engine, engine panel etc.

In a similar situation i got buzzer going by connecting equivalent wire to earth but then half sounded continuously some times. Did without sounder until whole new engine and alternator fitted

Apologies for the thread drift. I'll post a fresh thread.
