It is possible that the Sterling output transistor is blown short. Which type of Unit do you have? PDAR or DAC12 If the PDAR did you connect the Alternator temperature sensor? I suggest you check the the wire connected to the the Alternator brush pack is not trapped somewhere (between the Alternator and the controller) and shorting to ground. > >I have just replaced 6 dual purpose 110amp/h x 12-volt batteries as >the old ones failed after 4 years service. You did well then as a liveaboard. Why do you buy "Dual Purpose"? -- Richard
