Hi
I am making a 12v charging set for my barge using a yanmar L40 power unit (3.8PS) with a belt driven Leece Neville 110-555 alternator. 12v
I find that the alternator prevents the engine from running up to speed because my 2 Rolls 4000 batteries demand full power immediately if they are discharged. I am driving it at 2000rpm which is around 90/100a on the power curve. I have seen 100a momentarily on the clamp meter but the engine couldn't handle it and grunted a lot. If I put an isolator on the positive to the battery so I can turn the alt on and off is this going to blow the rectifier? Its a self excited unit with just + & - wires..
There seems to be conflicting information about this subject.
Any help will be appreciated. This is for testing and fine tuning. Obviously I don't want to damage that superb alternator but it does seem to be built like a tank so maybe its OK? I will be fitting a sterling or similar digital regulator to the final build.
Anyone know for sure if it has surge protection on this unit? Presto lite 8LHA2070VB WITH 8RG2112 regulator.
Thanks
