Has anyone ever had a problem with their alternator charging useing a led style lite. Mine quit charging and ive put 4 new alternators on it and the lite still wont cut off and charge. I took the led style lite off and used my test lite and it turned off and started charging. I dont guess a led type lite will work for the alternator lite.

LED's are diodes and will not allow current to flow in the opposite direction. With the LED, it would see the 12 volts, but the reverse flow 2 volts would be stopped by the diode nature of the LED.

KEVIN I JUST PUT AN LED ON MINE AND IT IS CHARGING ,WHEN YOU FIRST START IT YOU HAVE TO REV THE ENGINE QUITE A BIT TO GET IT TO START CHARGING BUT ITS BEEN WORKING. THE LIGHT I USED WAS A 2 INCH MARKER LIGHT FROM TSC,ONLY PROBLEM SO FAR ITS NOT QUITE BRIGHT ENOUGH IN THE BRIGHT SUN,PROBABLY GONNA GO BACK TO REG. BULBS

exactly what he said. you cant use an led you have to use a normal lite

kevin, i have a normal empi light wired to mine and haven't had any trouble. hit the key the light excites the regulator and go.

Thanks for the info guys. I got it charging now. now its time to spank some ass.

I put a led on mine and it wouldnt do squat . I wired in a 194 dash bulb in line with led and hid it inside the dash panel so i could keep my led in the dash face and it works fine now
