Anyone know the gauge of the factory battery cables on the Ex's? I'm trying to eliminate all possibilities with my constant need to replace batteries and alternator every 6 months or so. Thanks. I was going to upgrade to a 2/0 or 1/0 marine grade tinned cable since I can get all marine products at cost and the tinned wire resists the corrosion the best.

Thanks in advance

 

00.... but seriously I have no clue. Bumping this back up to the top so someone can answer it

 

My nephew had a similar problem with his 6.0 F250. Turns out some bonehead PO or mechanic had tapped into a fuel injector power wire to get power to something else.

Wiring was fixed and there have been no dead batteries or dead alternators since.

 

Oh yeah, tapping into a fuel wire? Great freaking idea! Might as well tap into some of these unused airbag wires too while we're at it!

 

Offhand, I don't know the exact AWG of OEM Ford cables.
That said, w/ the amp draw of your 7.3s starter likely the heaviest load, you will be fine w/ 1/0 (up to 15' total Pos & Neg run).
Make sure you shrinkwrap, use proper crimping tool & use correct lugs on all connections.
Based on your symptoms, I would be replacing the alt output wiring as well.

 

Was it actual power or signal to a remote start

 

I do not know, but it sure screwed stuff up.

 

I have that info. Which cables in particular do you want to know?

 

Check and see if you still a blanket around your batteries. This is what was killing batteries on my '01 Excursion every 2 years every fall. Since removing them, the only problem I had was the Texas heat drying them out. That's since been remedied by keeping them topped off with distilled water.

 

I'm going to replace all of them. I would appreciate the help if you could.

Thanks

 

In case helpful.

I'll try to have it up later tonight if I don't pass out. I started working on cars at 7:30 am and I'm only taking a break right now. I have to finish the third car today so my brother can have it to get to work tomorrow.

It sucks getting older. Too many pains an creaks.

 

I have a 2000 with a V10. Ours were 4 gauge. The ground cable is stripped in the center and has a tab that is bolted to the frame. When I made new ones I ran a cable all the way to the engine and then made another cable for between the engine and frame. I used 1 gauge I think. There are pictures in the thread I did of installing our Banks headers. Sorry I don't know how to link to it. Carquest made the cables for me.
