QuestionHello Von
I drive a 92 nissan maxima with 209500 km
3 months ago my car stalled on the road losing power at 208500km, I replaced a new battery.. next day it die on me again.
I took it to a mechanic, he installed a new alternator but the battery warning light still comes on. He then tells me i have to replace the warning light system .. i think this guy just taking me for a ride. It already cost me a total of $450 to replaced the alternator and a hole in the tailpipe. Now he tells me i have to cough up another $100-$200 to fix this battery warning light.. (i didn't do it) and one more thing he screwed up installing the alternator at first.. my car got all smoked up because one of the belt got caught on the alternator and the belt snapped.. he later fix it and gave me a new belt
The car is working fine for 3 months but the warning light still comes on.. the car stalled at 209500km while i was waiting at a red light.. i had to tow the car to another mechanic // he replaced the distributor cap and now the car is running again but still with the battery warning light on.
I already tried disconnecting the battery cable for 15 minutes .. once i drive again the battery warning light pops back on again.
when i put the car gear at park (P) the battery light doesn't come on.
when i step on the brake the battery light sometimes go on and sometimes it doesn't.
when i put the gear at park(P) and step on the accelerator to rev the car
500 rpm > no battery warning light
1000 rpm > no battery warning light
1500 rpm > the battery warning light goes on again
when i shift the gear from park(P) to drive(D) with my foot on the brake pedal.. the battery light will come on in a dim way not very bright.
once i start driving around the battery light will come on and off .. and sometimes stay on
please help me out
please give me some idea of what's causing it
If the alternator is faulty to begin with that's what i suspect or he didn't installed it correctly which is triggering the battery warning light to go on.. how can i check if the alternator is working properly ?
It already passed 3 months, so i don't think the alternator is under warranty and if i take it back to the mechanic.. he's going to charge me an arm & an leg again for testing & checking.
Can a belt that's not too tight trigger the battery warning light to come on ? The top belt is very tight, when i push my finger down it doesn't even move a cm.. the alternator belt is tight but not as tight as the top belt if i push it down hard with my finger it can move a little
I have a major headache and already spend a lot of money.. please help
thank you..
AnswerFrancis,
The battery warning light system works off the charging system. If the car is not charging the light will come on. If the alternator is not wired correctly the light will come on. If the master fuse is blown (at the positive post of the battery) the light will come on. The light runs off the principal that the charging system has to be charging the battery. If there is more of a draw than a charge the light will come on. I would go to another mechanic and have them look at the connections and also perform a load test on the system to make sure the charge system is working correctly. I bet this is something as easy as a wire coming off or a connector not being tight or damaged.
