Well this is my problem. I've gone through 3 or 4 main fuses in the past 3 weeks. The first one blew went the alternater belt snaped. The second one blew after that, i though it blew maybe because it was damp when i changed it. Last night after it rained, I blew the fuse again. Then i chaged it and it blew right away. The other times it lasted for about a week or so. I change it again today and well it works. I know nothing about wires and such. So if you could tell me were to look what to look for, or if it's to hard for a newbe to handle, what i need to say to the guy when i bring it in to a shop.

 

Same thing happend to me, the only way this is happening is because your stock top mount intercooler touches the nipple on the back of your alternator and makes a short. I would check to see if the intercooler is touching anything or not, that would be my guess.

 

that's for the idea, but my car's an na. OH i almost forgot, there is something wrong with the alternater, sometimes the volts just to 16. that would be the regulater in the alternater right? is that problem also blowing my main fuse.

 

It sounds like your alternators pooched. Get either a factory mazda one, or get yours rebuilt. There are some horror stories of getting it rebuilt, but i have never had a bad experience with it. Or you could get an FD alternator.

 

have had the exactly same problem 2months before...

i've put in another alt and everything was fine

 

Alt should never exceed 15 volts or damage will occur to the electronics in the car
