When I have radiator fans on, full blast heater fan, and I am at idle
i notice my voltage drops to ~12v. On a rare occasion it will loose idle.

Normally the voltage range is just a tad off 14v.

It is particularly notable when the radiator fans kick on.

I think I have seen it drop to 12v and then immediately back
up -- other times it seems to hover ~12v. Battery is new (a couple months old) as well.

I've replaced the alternator and it improved from the previous alternator
but still does it. previous alternator was a few tenths volt lower,
and a ~200rpms lower on the idle drop.

I've checked the voltage with both the gauge and with a meter.

what should I be looking for?


thanks,

Mike
