The Big 3, Everything You Wanted to Know + DIY

What i still don't understand is that if you are going to put a fuse in your big three upgrade, what about the other wire that was originally supplying the power? So say if the fusable link is good for 100 amps and the upgrade has a 100 amp fuse in it. Really you are not accomplishing anything you would be able to draw 200 amps, almost double what the stock alt can even produce. Explain that please...

This is why you're supposed to replace the stock line, not leave both installed.

Not sure why ZZP says "yeah go ahead, add this unfused line on top of all the fusable links.

I agree. If you do the big 3 just protect your investment. Why enhance a system, but leave yourself at risk? May cost you more later!

My Big 3:

1. Replaced battery ground to chassis with a larger ground.
2. Straight fused line from battery to alternator.
3. Replaced all engine to chassis grounds.

That should do it in a nut shell!:th_thumbsup-wink:

That's not the way fusing works. They would still pop at anything over 100A.
 
I'm not sure if anybody wants to comment on this...I put a new block terminal on the battery and ran straight back to my amps with 4awg. It's fused right at the battery and at the blocks in the trunk too. Maybe a bit much... :)
