Alternator wiring

[EclipsedFLA]

Now, Before you guys jump on my, Ive searched multiple ways to word my issues, so please let me explain...

NO power steering leaks

I turn my A/C on and my radio will die and all dash lights will come on as it is slowly wanting to shut off, one case it did leaving me 60+ miles from home in the middle of no where..3am and on top of it my phone died.....(very bad night) any way, after that I have a brand new alternator (REMAN..from ADVANCE AUTOPARTS I know They can be junk sometimes 75 amp i believe).

All was good for almost a month, as I replaced it, I wired new end connectors for the power to the amp (2 wires) thinking it was losing its connection.. later on as I use my blinkers my lights dim, and again when I used the A/C radio died and dash lights came on. I went to advance for a testing (again I know people say those tests are junk but I have no other options and any read is better then guessing). battery was good, just showed low voltage. and the guy said I should check around the alternator.. Ok i thought.. kept driving 2 weeks later (today) I had gnarly Idle surge.. Brand new thermostat, I read somewhere to check it out, then I drive to advance again and on my way home radio cut out, and dash lights, and now she wont start.(Flash back from last time i was stranded)

I plan on throwing a galant alternator in, and throwing a 4ga wire to replace from the alternator fuse to battery?? maybe that will solve it? or should I also do it from the alternator to the fuse?

I have pics of wiring from fuse to battery, should the white wire with red stripe be spliced into it?

any inputs? my car is down and I work 2 jobs, one all day then on all night.. I need to get back on the road ASAP.. thanks DSMR'S

Sorry for the short story.
this white with red stripe wire

What is that picture of the spliced together wires? You say its coming from the A/C fan fuse?

I'm pretty sure that's not what its supposed to look like, I can't imagine that came from the factory that way.

Perhaps whatever that other random wire is connected to is backfeeding current somewhere it doesn't belong.

Also, in any big 3 upgrade tutorial they will tell you to fuse the alt to battery cable but in all the installs I've ever done I never have. You just have to make sure the wire is safe wherever you put it, use loom and zip ties galore. YMMV It's no different than any other wire attached to the battery. Seriously, if you mess up it can barbecue your car, seen it more than once.

If its the same as a 1g, same color wires anyhow, the white goes from alternator to fusebox then fusebox to battery, the white/red is a power source to the interior fusebox , and yes there are a lot of wires that come from the factory like that , sensor ground 5v for sensors and 12v for sure use that type of connection.

 

[Miakehl]

That's nuts. Who woulda thunk it? If it works I guess. Anytime I ever install anything I never tap into lines like that, Never would have guess it was factory.

It still seems there is a loose connection somewhere. I know electrical diag is a PITA which is why our shop doesn't have a maximum diag charge for it.

There's a lot of strange silly things I encountered when hacking the harness.

Compression, so that like tapped in the wires from the fuse to the battery are supposed to be like that? Reason I am surprised is at the fact I've understood you can rewire from the fuse to the battery using a 4ga wire instead of those 2 white ones, not one write up explained splicing a wire into it. I thought that may have been where the drain was coming from.

So I am thinking upping the amps using a 97 galant Alternator, using a 4ga wire from the alternator to the fusebox, then a 4ga wire from the fusebox to the battery.

and of course while I am in the harness looking for exposed wires and covering up open ones like Miakehl said,

Thanks guys for input!

yes, there are quite a few wires like that. Does that white/red one go to a fuse called "battery" ?

Maybe the 2g's are wires a little different, in this pic you can see that metal tab where our alternator wire screws to the fuse? well that metal tab provides power to the rest of those fuses is apears

That wire is obviously a 12v source hooked to the battery at all times as well seeing as the alternator is always hooked up. so you can just tap it anywhere really as long as its a 12v source.

It appears to be coming from that 20A fuse labeled cond. fan in my 2nd picture, Could that be a faulty tap area? should the white/red wire be tapped from a fuse labeled battery? I just put the 90 amp in and she runs good, But I have a very strong feeling I will be back in this position. my check engine light (always on due to egr) Still will dim while I use my blinkers Soon Ill throw 4ga from the alt to the fuse, and see what changes that does. and If I have enough Ill do it from the fuse to the battery, and I will include that line tapped in?

In your link, I do not believe It is the same wire, this is ran into the fuse

 

[compression]

You may be right, alot of the wires are different colors between the 1g and 2g. Unfortunatly i don't know enough about that electrical system to give you an accurate answer. But i do know that wire should be enough to keep everything in proper working order.

A wiseman on here "Steve" is probably one of the most qualified to answer electrical issues, maybe send him a pm and ask him to give this thread a glance when he has a free moment.

Thank you for helping!

Anyone know where I can get a big 3 upgrade because my car is running like shit I am hoping this will fix it along with maybe an ISC?

Ever solve it?
