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.... |

People read previous posts. His voltage reading is inacccurate because he is not load testing. At 2200 rpm you adjust a varible resitor till you get a current reading of 33 amps and check the voltage. The varible resistor creates a voltage drop so Aaron's 15.9 v unloaded could be 14v with the load.
