Alternator plug

[HISSIN50]

Hello,

I Hope everyones' holidays are going very well.

I have a real quick one and am short on time to search too much. On the '94, the alternator's main plug and harness (3 wires, plus stator wire that branches out from the same harness) looks like poo. The wires have missing insulation, etc. I called a couple local chains to see if they stock the plug - they said no. I am thinking that places like FFI and LRS will have the plugs but I wanted to ask if anyone knew of local places (chains) that might carry the plug (I wondered if locals could not find it due to it probably having weird or different names). Then again, I could not find it on local stores' websites either.

If anyone has hints on where to get one for a good price, I appreciate it.

Thanks guys/gals!

JT, I doubt any parts stores carries those plugs. Reason I say that is this, when my alternator cable fried the first time, I needed all new plugs too. I also needed a voltage regulator, I went to several local parts stores, and nobody carried any of what I needed. I ended up ordering the stuff off of 50resto.

Thanks Chris.


I think I will get an overdriven pulley for the alt. If you folks do that, what do you get? I was thinking of something along the lines of 1.75" - 1.875". Thoughts?

Thanks again Chris and anyone else who might reply.

Overdrive pulley can be had here >http://www.performancepartsinc.com/

What was the outcome of the melted alt plug JT?

Seems like I have heard this before
but
for some reason, I wanted to associate the prob with Fox Stangs.

Foxes did like to melt alt wires (there are two plugs on a 2G - one plug contains two 10-AWG charge wires and those wires are not exactly overly generous in terms of load-rating).

For now, I had to break all the OEM vinyl tape off the harness (it was vulcanized and came off in hard chunks) so I could take a looksie at the wires. All were missing insulation so I just taped them so they shouldnt short to one another. I ordered a replacement harness from LRS (though after talkin to 89 Sleeper, I should perhaps have used FFI's harness - a nice beefy piece). BTW, I hope to never use the word beefy again.

I raised the idle a hair for now too (using that stupid air bleed on the IAC). I will have to see what it does. There is a reman'd alt on there now (from the previous owner) so who knows how long that will last (I have been wanting to put a new alt on. That requires money though). I was going to put the 160 amp unit from the '88 on the '94, but once I saw the wiring, I chose not to (I wanted to see if I a 160 amp alt would be sufficient, or if I would want a 200 amper like Chris got).

So that is where I am at now. It will probably take forever to get the harnesses shipped so I just wait.

Thanks again guys ( Chris, Danny and Grady).

Last but certainly not least, Chris I just read your PM. I will get back to you here in a few. I need to take some measurements real quick and crunch some numbers to see how small of a pulley I can use without reaching critical speed. Seems to me that alts can spin at about 15K RPM.............
I really appreciate the offer - once again the great guys at SN come through.

JT, I'd snag that 200amp alternator off of eBay for the price. I only drove the stang for 2 days with it on before my starter took a crap, but it seemed to charge okay even with my underdrive pulley on (although I think I am gonna put my stock pulley back on instead).

Yea, just lemme know what you decide.

Thanks Urban. I almost ordered my alt plug from FFI but ended up going through LRS (which seems to have the stator wire backordered. ).

In chatting with a very knowledgable member here after I ordered from LRS, he was saying that overdriving the alt with otherwise stock pullies was not wise. This was news to me but this guy is a smart one. That's why I want to crunch the numbers to see if I will be near 15K alternator RPM with a slighly overdriven pulley. I still have not even measured my current alt and crank pulley.

But this member had nothing but great things to say about his experience with FFI - I had not heard feedback until then. Just in case anyone was in the dark like I was..........

So now I wait for the regulator plug and the other 40 bucks worth of crap I ordered but dont need right now (we need extra fuel tank grommets and idler pulleys, right?).

Chris, I am gonna try to measure that stock pulley tomorrow. Since I am being a pain, do you know the diameter of the pulley you have?

Thanks again guys!
