BIG THREE DONE!

Nice work but you might want to actually crimp the terminals on or solder them in instead of whacking them with a hammer. Engine vibrations can and will shake them loose.[/QUOTE]

The Harbor Freight crimper works great and it didn't cost me a thing since I returned it. Works on 1/0 terminals.

I almost did the crimping tool but the hammer combined with the wrench to make the dimples seems strong. I thought about solder as well, but heard it can vibrate loose unless you also make a crimp. It seemed very nice but if I notice a problem I will pick up a crimping tool at do it the the right way I just like hitting them lol, was fun.

Hello All,

I did the BIG 3 today. It was an interesting project. Used a kit I ordered from Amazon and had about 8 inches of wire left from 9 feet. I used:

and

I ended up gaining a couple more needles past 14, hovers between a higher one and lower one. Truck seems to start quicker and the blower motor works better as well as very very little dimming when I used the power windows. Worth it if I do say so myself.

Don't mind the yellow wire (that is my light)

Will you please explain to me what the big three is? I have no clue what you were talking about.

Did this awhile back to my trucks as well and there's an obvious difference.

Hammered all my ring terms as well and then solder - they ain't comin loose. @S1nemesis Did you fuse between the bat and alt? Just ran black loom over all my red/hot wires last night on both trucks to clean things up.

Smrtss1 - Does it seem like the wiring the 12 are 'up to *****'? It's certainly an upgrade to all of the NBS trucks with added load or not but haven't really examined how GM is wiring their newer trucks.

It involves adding large gauge wire (1/0) between the main electrical points in your vehicle. Usually between battery + and alternator +, between engine and frame (ground), and between battery - and engine (ground).

No fuse @BeenChevy - bad idea? I left the factory stuff.

It's definitely a good idea. You don't wanna be the guy caught on fire on the side of the road when the main power lead shorts to ground. At least shield up the lead from your alt to pos batt lead.

Already had one instance where my battery want secured properly and the positive terminal was welding the DS fender after hitting a bump in the road doin about 60. Just be careful

I didn't use a fuse. Bought the holder with a 150 amp fuse but decided to leave it out since it's just a short run and the welding cable I bought is heavily shielded as is, plus I added a split loom to it. I didn't want more places for the connections to fail. If you add one, make sure to tin the wire if it's the type that uses a set screw. Most people don't use a fuse from what I could find out.

 

[S1nemesis1s]

Will do, I think I will put some shields up and see how it goes. hmm...

 

[BeenChevy]

Good point on the tinning. Don't waste your time upgrading any of this by cutting corners. Sand your ground points to bare metal and go heavy with the solder filling your rings.

The liquid electrical tape they sell now days is the shhkt over your exposed ground points, where you've sanded and anywhere moisture wants to get in on your new runs. It dries super fast and doesn't seccumb to road salt.
