just did big 3....

[el rafa 10+ year member]

I did big 3 using 4ga. I added the 4ga from bat-chassis, added pwr from alt-bat(left orig there), and added engine-chassis, all to same bolt on chassis. My lights are still dimming, but not as much as before. So I guess it helped a little.

Car: 06 stang GT, stock battery and stock alt.

Amps: JL 500/1 and Alpine F450

specs for alt: 80/135 amp (max) @1,800-6,000 generator rpm, approximately 525-2,000 engine rpm

Can't afford new bat or alt right now, but which should I get, and will that fix my problem.

battery will be cheaper and in the long run stil a must. i'd say go with a battery first

Make sure you have your grounds as clean as possible. Any paint etc at the contract point will diminish any gains the larger wire would have. Since your car is not all the old the battery is more then likely fine but it would be a good idea to have it checked.

Yea bro, Just make sure the area around the bolts are cleaned up. With those 2 amps you are running you shouldnt be getting that bad of dimmage..

Are you saying you idle at 525-2000 rpms?? Or is that normal driving RPMs?

I sanded a little where bolt is at. I'll sand again real good. What kind of sealant(sp) or spray can I use so whatever bare metal is showing won't rust? Was hoping it was battery cuz lights weren't dimming till I installed the Alpine F450. Gonna get some readings from my dmm with music on later after game. Anything else I need to check?

thanks

That is what the manual says. Figure I'd post it to help diag my problem.

I idle about 525-900 and drive about 2-3 thousand if I don't hit the pedal.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
