guys,
im having a heck of a time trying to figure out whats the problem. Gen light came on thursday night on my drive home. i measured voltage goin to the battery as follows: car off ~13 volts car idling 14 volts 1500 rpm 15.8 volts BAD i borrowed a new voltage regulator from bill 'grimstead' and it did not rectify the problem. all fuses are fine. all connections are solid. the belt is on nice and snug with the car off, the G light is lit car idling, it is lit, but very dim.... higher the rpm the less bright the bulb becomes.... now that i have eliminated the voltage reg as a failure mode... do i have a crapped out alternator? where is the best place to buy a new alternator? help me before the WCC... i dont want to blow up my optima.... |

But that is without a load on it. Alt are meant to be load tested for accurate readings. If you are 2200 rpm you adjust a load resistor to have a current flow of 33 amps. That load resistance causes a voltage drop which gives you the voltage. Basic electronics.
