charging question
Hey folks, forgive me for asking this on the barn but its were I am comfortable.
For reasons too long to explain I put an electric fan in my 34. The car is converted to 12v and I'm using a typical GM alternator. All works well except I notice when the fan starts and I am at idle the amp gauge drops dramatically. Once I step on it a bit it comes up. I always thought an alternator put out the same amps at slow speed or high. Do I need a higher output alt? Better batterie? I am using a group 35 batterie like a small Honda might use to make room for dual exhaust. The alt is three wire with a diode. I cant recall the fan amp draw but its fairly high. Ken
