I didn't mean to get you upset. I was just keeping the debate going. No hard feelings. Call powermaster tomorrow and see what they say. Hell we might both be wrong.

all the talk about voltage spiking... i was never referencing it, i was precisely told over current, never voltage.

I'll find out today.

ok, i got the information.

Apparently, what i was told was.... W to the R.O.N.G

It's stated that a battery can accept any current without failure, it just isn't wise to do it for longevity purposes but i wasn't referencing that aspect of it as a slower trickle charge is required for maximum potential.

The REAL worry is this-

The alternator should NOT be used as a battery charger. Alternators were not designed to output it's rated output at whatever RPM constantly. For music, it's fine because music is dynamic. Bass tracks are pretty much the same. Now, if you plan on playing test tones for an hour straight... well, that's different.

It, again, all comes down to heat generation and can kill an alt if too much exists.

Point being, if you have dead or near dead batts or a large enough battery bank that is discharged enough to force the alt to charge for a long time... like a situation where a battery charger would come in handy, this is when not to use the alt to charge! Risk of overheating alternator.

wow very intresting thread
