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.... |

K.I.S,S
keep it simple.... look for bad grounds... motor to chassis and motor to battery. also dont over look corrosion at the alt. mounts and connections. it could be a bad battery. low internal resistance will cause high charge voltages. test it with a battery load tester. or charge with a battery charger to full charge 13.5 volts @ 2amps then put as much load on it from head lights, high beams, blowers and with a vom look at the voltage drop. try to calculate amp load, ie; headlights 55 watts = 55/12=4.5amps and then you can calculate voltage drop/ time and amp load will tell battery condition. |
