Griffin radiator and twin fans still running at 190-200?

Don't drive this car at nights and heater is not used as car is stored in the winter. Radio is solid state and a/c compressor is a new sanden compressor which hardly draws any big amps? Car has a high flow mechanical fuel pump? So I do not think that alternator amperage draw is the problem.

Yeah but what do the fans pull? My fans will pull ~35 amps on start up, and only drop into the mid-twenties on the lower speed. That doesn't leave much. Also consider that your alternator is not capable of producing 65 amps at any given time. At idle speeds it's not capable of putting out that much. I forget exactly how they're rated, but I know for a fact that the rated output is not what it will put out at idle or lower speeds.

I run a 100 amp alternator on my car.
