Not the size of my table saw motor but with the starter motor rated at .95KW

the current demand is approaching that of the starter motor, if I figger

correctly.  That's pretty serious current.



I had a 80 amp alternator on my sailboat auxilliary diesel engine the output

of which I could control  manually.  I would normally put 60 amps into the

batteries during charging  and it would seriously slow down the engine.  I

wonder what size wiring they recommend?
