alternator mega fuse melted?
#1311285 - 09/02/06 06:38 PM

Recently I changed out the headagasket so most of the car was all apart. About a week after I finished i smell a burning plastic smell, finally pinpoint it as the alternator mega fuse. The passenger side part of it the nut wasnt all the way tight and that side the case is all metled. it even manged to burn its way about 1/4 of the way through the screw.


My question is did this happen from the nut not being tightened all the way and leaning against the plastic or would this be from improper wiring of the alt. everything looks okay with the alt and the car never had a problem with charging.

Ah yes high current and loose connections don't mix. DC or AC Just smallest increase in resistance above 0 ohms turns into heat.
This the same thing that happens to connector on the blower resistor pack. The bk/bl lead spade looses tension and zttttt!
Cost cutting/using the wrong type of connector.

Thanks for sharing.

I Had this happen to me last Feb, except mine burnt all the way through and left me stranded on the highway. I forgot the fuse was there and assumed it was the alternator. After I got it apart and had my alternator checked out I remembered about the fuse. The fuse and replacement wire was $93 from the dealer, but I got one at a salvage yard for $5.

I'd just got find one from the junkyard. You can use the one off the zetec, its the same, and a lot easier to get to.

Maybe, if the wires to the fuse are bolted tightly, and free of tarnish. Make sure it's insulated.
