I wasn't really paying attention when i was puttin my battery back in my car and i put it in wrong, I put the positive on the Negitive and negitive on the positive. Now my parking lights,door lights, AC, Cd player and probably some other stuff i haven;t found out yet, do not work. I bought a circut tester to see if i blew a fuse but none of the fuses work even though none of the fuses are broken. Some people have said i may have done somthing with my relays? I don't know ? can yall please help me out? Thanks, Mark

1. Does the vehicle start?
2. When you the fuse(s) are you testing using resistance, or voltage drop?

the car starts. "2. When you the fuse(s) are you testing using resistance, or voltage drop? " what do you mean by that?

You should have blown a fuse... have you checked under the hood? ------------- If we learn from each success and
each failure, then we can improve ourselves

Yes, even the fuses that aren't blown don't light up. Any idea whats wrong?

I bought a circut tester and when i check the fuse the tester doesn't light up at all.

what type of car was this? thats my only guess is the fuses...sorry I cant help  ------------- If we learn from each success and

this is a 95 maxima.

this is a 95 maxima. well i can't test the fuses b/c none of them will light up so i am thinking it might be something more serious. I might just un-plug each fuse and then plug it right back it. It might reset somthing.

well in a civic ex had that happen once my girlfriends brother tried to put a new battery in our car and placed it in there backwards.... well given it was dark out and the flash light was sh*t, he checked the fuses an they looked good, when I got home from work went out there and checked the fuses and when I started to take them out I found one that was blown, a little square plastic cube like fuse which you place in place with a couple of screws....anyhow it ended up being a fuse... also as for that circuit tester I would shy away from using it wouldnt want to mess your car up anymore  ------------- If we learn from each success and

Was it under the hood?

It's possible that you might have blown other circuit protection.. something like a fuse link. If it appears you're not getting power to the fuse box at all, I'd see if I could find a wiring diagram of the car and look for other fused protection. regards, Jim

If a fuse-link is messed up would it prevent my from testing my fuses?

The first thing you need to do is measure the voltage on the battery. The OCV *open circuit voltage* for a 100% charged SLI battery will be aprox. 12.8 - 12.90 volts DC.
The next thing you need to do is varify that both cables, power and ground are indeed sound in connection and fitment. Make sure there is not an open in either cable.
Take your DMM and measure the resistance and the continuity of both cables with the battery disconnected from the vehicle. The ground cable should measure less than 2 ohms aprox.
The (+) power cables from the battery, leading to the fused power distribution block should measure the same resistance, you will have to disconnect the other end of the power cable from the fuse block so as it measures the cable resistance and not the misc circuits attached.
If both cables are indeed fine, and the battery measures fine.
The next step is to remove each fuse one at a time and varify each visualy, and with a DMM to ensure they are not open. This includes all the fuses in the cabin.
The next thing from there is to obtain either a Helms, Mitchel, or Auto Tek information for your model year vehicle and check each circuit affected.
If you are not up to the task then you are going to have to bow out and bring it a a technician you trust, to trouble shoot the problems.
Good luck

What does DMM stand for?

Digital multimeter. You can also try using a voltmeter to see if ur getting voltage at your fusebox. Ground one of the leads, pull out a fuse, and stick the other lead into where each of the fuse blades go. One shoud be zero, the other shoukd be ~12.6V Godd luck, and hope this helps
