Yesterday afternoon was in the my shop with one of my many projects,had not used my car in a while,so decided to start up the car and let it run a while, this is what I noticed.......

Start up,nothing on but the engine running,MSD ignition,volt gauge just under 14 volts....

after the temp got to 180,kicked on the electric fan, volt gauge dropped a little,still way above 13 volts....

for the heck of it,turned on the headlights on high beam,turned on the heater blower motor on high,only thing not on was the W/S wipers and radio....
volt gauge needle was just to the right of 13 volts.....

no matter what was on, it never got to 13 volts, always a tad over 13 volts.......

all this at 900 rpm idle....... and with a 15+ year old Ford 60 amp old style alternator.....
