headlight drain

588 Views 2 Replies 3 Participants Last post by  pmullaly
have any of you had any problems with your headlights draining too many volts out of the battery? it seems that my voltmeter drops almost 2 volts when i turn the headlights on. i have already had the battery drain so that i couldn't crank the engine. i've put a new battery in, but the headlights still drain the same. if any of you have any possible solutions besides testing every wire, i'd be very happy to hear them. thank you

Is the car running when you are taking the measurement? Headlights take a lot of power. What do you measure on the large red wire on the back of the alternator: Engine running & headlights off.??
