Hi all....latest update !
Fitted new alternator that arrived today from beta who had all my engine details....still warning light wouldnt go out or the buzzer....took a cable from starter battery alternator to + on starter battery and alarm stopped.Thought maybe nothing wrong with the origonal alternator so put that back on.
A friend of mine who has more of a clue says its the splitter(and regulator i think, by sterling power, 90 amp split because i also have a battery for bow thruster....left boat running to charge up domestics and run boat for 2 hours.....when i went to restart the boat later no power to start !!! Hope its the splitter / regulator whats the problem.That wont be here till Saturday.Would this have now drained the starter battery?
Maybe its the alternator and regulator ?
