I have an 85 f-350 and the alternator does several things only two make me want to shoot it 1 st things is under a load the alternator get warm(i know this is normal) but it slowly loses power but when it cools off it is right back to full power. The 2nd thing is that at idle if you run the lights and heater fan you can see on the volt gauge it dropping drop it in gear and it dips below 11 volts.I have changed the alternator 3 time as well as the regulator I am running 1 ought cables from the battery and 3, 10 gauge wires from the alternator to the solinoid. It is a 100 amp ford alternator. I even installed a larger crankshaft pulley so at idle the alternator is now spinning 3 time that of the engine can anybody help me. Is there a better alternator that is made for putting out high current at low engines speeds or do they make a regulator that will excite the alternator at lower speeds and voltages
have the same problem?
