Re: Main Fuse???? (jsd300zx90)
Will someone let me know where the main fuse is in the 300zx? I need to replace soon.

You've got your finger on it. The blue wire is the main battery fusible link. Nothing wrong with it by the looks of things. Why do you feel you need to replace it?

My car will not turn. Only headlights work. So, I bought a new battery(Because my old one would hold a charge), hooked it up wrong and someone mentioned that I may have blown the main fuse. So I need to look at it and see if it's blown, and replace if needed. So how do you tell if it's blown? Not sure really what is wrong with my car.

Normally if that blue one needs replacing it will be burnt in 2. Seeing as your headlamps work it's ok as nothing works when the car isn't running if that blue FL is burnt. You could replace it if you are skeptical though. I would also pull all of those ones out and check if they are burnt out but from the photo they look ok. Easy to see if the little strip of metal is compromised. Short of that check all the fuses in the DS kick panel inside the car as well.
How long did you leave it connected backwards? What happened after that when you turn the key to ignition but not to engage the starter? Did the dash lights etc come on?
Connecting the battery backwards can do a lot of damage to things like fry the ECU, Alternator or pretty much any other electronic module or wiring. Hopefully you got lucky.

GOOD LUCK CAT!!!!!
Ok so after many days trying to figure out what is wrong with my car. Not turning, but headlights work. I decided to go mess with it again today. I walked up to the car and saw an Orange cat sleeping in my passanger seat.(Because my driver side window had been busted out from a MEMPHIS break in). And my Car now works!! It started right up w/ no work. I think the cat fixed it and then took a nap from all of his hard work. IDK. IDC. it works. Thanks kitty!

Fantastic....is there anything a cat can't do?
That is very good news. Often when a battery is connected the wrong way, it can destroy a lot of electronics. I would double check your battery terminals are clean and tight. There has to be a reason it's ok now, must be something simple.
Glad to hear for you it's all good again

Re: Main Fuse????
I had the exact same symptoms with my 1990 300z after I made the same mistake of reversing the battery cables during a charge. The exception was that I was using a Stanley battery charger and was not attempting to get a jump from another vehicle.
The web provided some good information that pointed to checking all of the fuses, relays, alternator, or ECM. Fortunately, I started with the cheapest and easiest items first, fuses. I found all of the interior fuses and relays to be fine. However,since I had seen smoke near the battery, I knew that either the battery itself, wires or some other components had to be burned. So I had a hunch to remove and physically check all of the fuses in the fusible link container since it was right next to the battery.
As soon as I pulled the cover off by hand (which came right off by pulling straight up) I held the cover near my nose to smell for electrical order and sure enough, I caught the scent of an electrical burning smell.I knew that I was close at this point.
I pulled them one by one and inspected for visual damage or smell. All of them were fine and passed a voltmeter test. All that was left was the big blue battery link fuse with the blue wire loop at the top. It looked fine and everything that I had read said that the damage would be visible so I never suspected it to be an issue.
I pulled out and smelled it and it smelled burnt. Then I touched the blue wire that appeared to be intact and noticed that it was intact everywhere except for the top in the middle. As a matter of fact, the only thing in tact there was the insulation, while the fuse (a small wire) was broken into.
I cut back the insulation and twisted the wire together and covered it with some electrical tape so that I could test this solution. I put everything back together and turned the key and got nothing. I almost forgot that the thing I still had to do was charge the battery, this time with the cables in the correct order because it had never been charged and was still dead.
Then bingo, the car started right up and I went for a 20 mile ride at 90mph to celebrate. Looks can be deceiving so make sure that the blue battery fuse in the fusible link box not only looks solid but is solid.
