Hey,
Ok, the 12v constant wire on my relay touched the
frame of the car and bzzzz, a cool buzz noise and smoke.
I knew I probably blew a fuse because my keyless entry
stopped working and I kept hearing a buzz. I checked
all the fuses (the normal looking ones), and they were
all fine. Not until I started the car and went to turn
on the Air Conditioner and it didn't go on, that I
realized I probably didn't check that one. I checked
it, and it was blown (40A).
This is one of those bigger fuses, like you would find
under the hood in the extra compartment. Is this just
something I'll be able to find in the auto parts store,
or do I have to go and order it the long way?
'92 Acura Integra.
Thanks!

You should be able to find it at an auto part's store if not you should be able to get one from a local audio shop but it may cost more there.

You can get these at the local auto parts store. It's the Green or the Red plastic box with a small copper wire in it that you can look through the clear plastic to see the fuse. They sell for about $4.99 up here in Canada. ------------- Jeff

cool, thanks guys. yea, it's the green box-type one. I couldn't pull it from the fuse box, but then I realized there was a screw above it and one below it. So I guess I have to unscrew them first, and then pull the fuse? (Of course this blew right before I had to go on a 90 minute drive in the 90+ degree weather....no A/C or radio! AGGHH!)

Yes, you have to take the two phillips screws out and pull the entire piece out ( The green box and the two copper angle pieces ) and bring it to the parts department and ask them for one and show them the fuse otherwise they won't know what your talking about. ------------- Jeff

(....learning, learning, learning...) ok, so I bought the 40A fuse from Strauss Auto ($2.50). Brough it over to my car, screwed in the bottom screw...ok.
Then, put the top screw in, and when I touched it with the screwdriver,
BZZZZZ (light and smoke). It didn't really come from the fuse area,
more like above it where your knees are. I don't know if I actually blew
something (because everything works fine), or if it just wasn't happy.
I undid what I just did (cause I would kick my own butt if I just blew the
fuse I just bought), but luckily it was ok. So, I undid the negative cable
from the battery, then plugged it in, then put the negative cable back on
(which sparked a bit). SO... after all that blabbering, my question is, are you always safe from blowing
fuses and other pieces if you disconnect the (-) cable? If yes, is it
bad that the cable sparks when you put it back, or is that normal?

You are safe if you disconnect the battery from the car when replacing fuses..but if there is a short somewhere, when you re-connect the battery then you might have some problems. Also, its usual for the battery terminals to spark when re-connecting the power wires. Little stuff like the radio, alarm, and ect. draw power even when the car is off..which in return gives you the sparks.
