Running at cruise (3000-3500 rpm) I have 13.5-14 volts on my gauge. Running wide open it drops down to 12.
I am going to see if it also does it on my second battery.
A couple weeks ago I blew a power steering belt at WFO and I lost power and my gauges went haywire for a second. The alternator belt goes around the water pump only. The power steering belt goes around the crank, water pump and steering pump. So, when the belt blew my alternator quit spinning.
I was thinking that a piece of the belt may have smacked the alternator and knocked something loose. Or maybe it stopped abruptly when the belt blew?
I just don't get why it seems to be working at lower rpms but not at high rpms.
