Alternator fuse keeps blowing Options

[CelicaGTS94]

Hey guys,

So the alternator fuse blew in my 94 GTS today, replaced the 7.5 fuse, everything was fine and the battery was charging again. I originally lost all my gauges, power windows and the car was only running off the battery. About 20 minutes after replacing the fuse, it blew again. I know i'm having a misfire issue in cylinder 3, the rubber at the bottom of the plug wire broke off so its not making a good connection. (Replacing the wires tomorrow) but my question would be...if its not getting a good connection and could be getting an arc in that cylinder, could that be shorting out the fuse or should i be looking at other wiring issues?

Any response would be great. Thanks

Well if the alt fuse blew sounds like the alternator malfunctioned. Was the battery light on at all if it was replace alt. I assume you checked the battery cable connectors because the can get corroded and cause the same symptoms.

You wouldn't happen to have an aftermarket hoodliner would you? I had the Dynamat Hoodliner (with an aluminum surface) that shorted out my electrical system when it got loose.
