G'day All,
Finally got my vintage '67 60hp SportFour to idle correctly in the tank so I could put a multimeter on the output. Voltage at idle was about 16.5V to 18.5V. It has a new rectifier fitted. Are these alternator equipped old engines not fitted with a voltage regulator? Am i correct in assuming I should only use a traditional flooded cell lead acid battery?
Is it possible to wire in a voltage regulator?
I have a cranking/deep cycle 100AH auxiliary battery in my 4WD was going to use in the boat on days out but I recall from somewhere that a high charging voltage will kill an AGM battery, and it wasn't cheap!
I guess sealed AGM batteries were unheard of in 1967.:rolleyes:
Thanks heaps
