long story short, last nite we picked up my 91 rx7 and towed it back on a trailer (it needs some work).
we jumped the car to start it and get it on cause it had a dead battery (all goes well let it run for about 10mins so we didnt flood it or anything).
but anywho we wake up this morning and go to jump it to get it off and my friend switched the negative and positive and the main fuse blew (started smoking) and it seems to be stuck in the socket..unless i need to unbolt something?. so im thinking ill probably need a new fusebox and main fuse?
I also will be needing the 80 amp main fuse.
so as of now with a new battery that i bought tonight nothing turns on or even moves in the engine we i try to start it or turn it on
i can take pics in the morning if needed

also if anyone knows where i can get this stuff or you have it PM me.

thanks in advance

not exactly how i wanted to start getting into 7's but when we first pulled in to pick it up, it was love at first sight

 

The 80A MAIN fuse is bolted in, one bolt on each side.

 

any know where can i get a 80 amp main fuse?

 

Yeah I made this mistake too. All the other fuses in the main box under the hood are this plug-in type. The MAIN fuse (big 80amp in the middle) is the same shape on the outside but the bottom there are two long metal prongs that are the fuse connection. You can get these 80smp suckes anywhere they sell car fuses. I was stupid and bought mine from the dealer cause I didn't "see" the fuse that I thought I needed at Advance Auto or pepboys. And the dealer markups are insane...$3 for a fuse, I could have just used an 80 amp kitten off the street...Meow.

So unbolt either side of the main fuse, Disconnect the negitive battery terminal FIRST!. And simply replace fuse and bolt back on...connect battery!

- MAX

 

i looked at napa and they didnt have it so i geuss ill look at pep boys or aa. one quick question does anyone know if its 80amp or 100? cause on the cover it says 100A

 

got the fuse at AA, im going to put it in tomorrow morning. damn drizzle and wind.

pic below - i bought it off a guy on the forum. she needs a little TLC but she'll be worth it

Oops, you have an S5 so it's 100A, S4's are 80A. Don't use the 80A one.

This is why a sig with your car's model in it is a good idea.
