I was driving a little agressive during the night but when I was getting to my friends house I noticed that my add oil light and add coolent light flased on when I went above 2.5k. So I noticed that they flased on when I hit 15.9 volts which is way to high. I drove back home at 2k to keep it at a 13/14 volts. Anywhere I could look for problems. Thanks. This is my first alternator problem.

 

get it fix now, im saving four a new bumber, and got to get my engine bay painted, as i had the same thing happen to me. one night after some long hours driving, the next day when i went to wash my car it had all the battery acid all over it, and it had eaten into my paint. here look at these pics

save the pic then go have a close up

 

My battery is in the rear bin that will cause damage also but wont **** with the paint... I just need to know would it be the alternator, or another electrical prob. Need suggestions. But thanks d1rx7.

 

the problem is the voltage regulator inside the alt. replace it or get a new alternator. you can get a remanufactured alt. at pep boys or advanced auto parts. if you can't find one PM me i own an auto parts store and i think i have one in stock.

 

thats the thing, coudnt think of the name, but yea its the regulator. i was going to get my fix, but found it a little easyer to get a new one, it was hard to find as i didnt want one off a series 6 (im in new zealand)as i got a series 7, and the amp is higher in them. i will get my old one rebuilt one day when i have some $. hope yours desnt do you any harm in the meantime

 

I was also wondering why add oil and add coolent lights up... Can you explain that, did it happen to you? And so there is nothing else that will cause me to hit 15.9 volts. And it only hits it around 2500 rpms. I dont get it. If it is the alternator i'll have no problem going to buy a new one, I just dont want to buy something then figure its a diffrent thing. Thanks again. The ldash light question is because I am not sure why those lights will turn on.

 

i dont think my oil and add coolent lights came on, it happen over a year ago but im sure they didnt come on, i no that when i took my car to a auto electricon, to find out what was wrong, he show me in the battery and it was all boiling away, if you do drive it mite pay to drive with the lights on and what ever alse you can.

 

i don't know why those lights turn on when the alt. goes bad. when i had trouble with mine they also turned on but my trouble was that the alt. was not charging the full 13.5-14v aprox. it was only putting out 8v. the wierd thing is the battery charge light on de panel never went on. i found out on the PFC commander.

 

Changing the alternator should solve your problem. You will also want to double check any and all your rounding points. These cars will do weird things when the voltage goes hay wire. If oyu have this problem in the future try turning on different loads (headlight, rear window defroster, climate control fans, AC.....by turning on all these items it will load down the alternator and keep the voltage lower than 15vdc and may or may not cause the voltage regulator to fail completely.

 

hey spoolin1012 r u gonna get a aftermarket one or a mazda one?
i need a new alt too, but mazda selling them $317 canadian dollers

 

with less than that you can get one with lifetime warraty at advance auto parts. see if this link works.

good luck

 

My car did the same thing with the lights. I cut it off and started it back up and it was gone. I would notice that for a while under boost the voltage would get up to around 15 and the lights would want to flash on, after about a week it just stopped do it. Where would the best place be to buy a new alternator. I see that advance offers two on the web with life time replacement, but the price is $100.00 apart from each other??????

 

of the ones they have with lifetime replacement the best is the worldwide. over all the best one is the bosch. their quality control on reman parts is the best.

 

I got mine rebuilt at an Alternator/Starter place, cost me 160 Canadian. Same thing happened to me, all dash lights started to light up, put a tester on it at idle, was getting around 16.5V, then I gave her a little gas to like 2000rpm and got up to over 20V. So I pulled it right there on the side of the road, (yes I have a voltage tester in the car and basic tools like 10,12, 14mm wrenches in a small pouch) called the girlfriend and got it rebuilt. New diodes, new voltage regulator, new bearings, new brushes. Don't do it yourself, Mazda wants too much for the voltage regulator and parts. I'm not sure how the guy rebuilds them for that much but, he probably gets the replacement parts for a good price. Good luck.
