what is the acg fuse for?

[llf51]

What is the 120A ACG fuse use for? It is located next to the jumpstart section of the fuse box on the driver side engine bay. Secondly, how do i properly jumpstart the nsx?

I also purchased a new battery for my nsx. It's the exide orbital 75dt. The guy at Kragen says this battery works for the nsx. I put the damn battery in and my engine doesnt start. It seems sounded like it was not having enough juice.

here is a link to my battery: http://www.autosupplyusa.com/75autbat.html

So for now I hooked up the new exide 75dt battery to my schumacher battery tender and we'll see how things go tomorrow.


thanks in advance for your help...

The 120 amp fuse mainly protects the altenator and supplys most of the circuits in the car. To jump start the NSX follow the procedure im the owners manual. Did you blow it by connecting the battery backwards. 690A cold cranking is more then enough to start the NSX so the size of the battery is not a problem.

i blew it by connecting the positive end of the jumpstart cable to the jumpstart connector and the negative end to the bolt next to the acg fuse called acg something... (it's right next to the starter connector thingie). I thought acg means A/C ground.

im gonna replace the fuse tomorrow. In any case, so why is my car not starting???? Do i need to replace the main relay? I have a 92 nsx? thanks briank you're awesome.

With the 120A fuse # 9 blown you the car will not run. Power is not getting to the ECU or the fuel injectors along with lots of other stuff. I beleive your main relay was not damaged.

Don't ground the negative jumper cable in the fuse box. Attach it to an egine bolt.
