I got a new battery yesterday so i could turn to gtu over and maybe put some atf in the engine just for s&g's before i start on the rebuild. When I hooked the battery up, the main fuse blew, i found out that it was because of the cap still being on the battery ( it was 11 at night in a barn out in the country..... kinda dark). I also found that the security system had cut off the starter and whatnot because I didnt have the driver's door handle on. I unhooked the 12-pin connector from the silver box behind the glove box, which a search through the forums told me to do when disabling the security. I then installed a new 80 amp fuse and it blew immediately..... any ideas?

Is the polarity on the battery correct?

Is the big alternator cable terminal end touching anything grounded or chaffing anywhere?

BigMike85

i assume the polarity is correct because the lights inside the car work, the door ajar light is on a lot also

WAYNE88N/A

Light bulbs don't need to have correct polarity to work fine...

Your alt, ECU, CPU, and several other components do...

the battery has the all black cable going - and the black with yellow going + , i guess i should check out the alternator tomorrow.... the car is 20 min away from my house at the moment

If you've got the stock wiring on her, the black with yellow stripe is NEGATIVE (ground)...

you just confirmed it, turn the battery around, you have it hooked up backwards and pray you didn't fry anything.

ive been reading wiring diagrams since age 13, since when does yellow ever mean gnd? ( never worked on a jap car before) thanks for the help guys.

If you would have read the main power diagram in the FSM wiring schematics, you would have known

Who ever said that black had to be ground?

are yopu serious? they made the black with YELLOW the ground!? thats the craziest thing ive ever heard :P my last 3 years of electronics classes jsut flew out the window neat lil tidbit of info though. does that only apply to the batter cable? or other grounds in the car aswell

The Black/Yellow larger gauge wire is the ground only on the battery.

And if you had three years of electronics classes, and still didn't get the concept that every single automotive manufacture uses a different color for power and ground wires, then you either slept through your classes, or need to get your tuition money back.

Apparently you have not been reading wiring diagrams since age 13, or if you looked at the wiring diagram you would have seen B/Y going to ground from the battery.
