Wiring help .

Well i finally started my truck and the alt. is not working. Had it tested and it is ok. So that leaves my modified wiring. Here is what I have . I tried to use a dodge electronic volt. reg. so I could cleanup the fenderwells for looks. I thing it should work. As for wiring it all up I have the bat. out of the alt. hooked up to tha bat. via the starting sel. I have a hot wire off of the ign. switch that splits with one side going to the stad. side of the alt. and the other side goes through the volt. reg. to the feild side of the alt. . The only thing I can thing of is to try and switch the feild and the stad. wires. If anybody has tried somethig like this or has any ideas it would be great.

Thanks SMOLDO.

what type of alternator do you have?

smoldo · Post by **smoldo** » March 28, 2007, 6:39 am

Ford alt. Just a standard Ford alt. 1969 or so.

You've got to be careful when you start mixing apples and oranges. The Delco, FoMoCo and Chrysler Alternators are wired a bit differently and therefore require different hookups to the Regulator or no regulator at all. From your description, I'd guess that your alternator has no output because it's not getting the proper exciter voltage (should be coming from the "Alt light" circuit.) If you're going to change it from a stock setup, and you want really clean fenderwells, the best method is to go with the 2 wire Alternator Delco mod (the 1 wire setups don't charge well at low RPMs)

The best All-Ford setup is this

I see Casey, host of SS08 thought so too.

That alternator bolts on to stock brackets?

Why do I need that many amps again?

The funny thing is, I just replaced that same type of alternator last week on my wife's 99 Expedition...the front housing is different than that one, though.

Oh, I forgot about the 'Tim' factor. heh,heh

One question I didn't see asked in those links (didn't read all pages, though) was how it affects the stock gauge...is the high amp alternator compatible with our stock gauges?
I wouldn't want my gauge to go up in a mushroom cloud.

Slick Fan,
The alternator should not affect your gauges at all, no matter how "powerful" it is. Remember, your system will only draw the power it needs so even if you have 150 amp alternator, your truck will still only draw what it needs to operate as always. If you have a really powerful alternator and your truck doesn't need much, your alternator will run very cool under a light load. That's much better than drawing a heavy load from a nearly maxed out alternator! Anyway, that draw or current will flow through the ammeter as it always has and your ammeter will work perfectly. As for voltage, a good alternator will put out 14+ volts vs. the old generator's 12v. So, your voltage gauge will read a bit higher but it will still work just fine.
As for putting a Delco in a Ford or whatever...I'm not a true purist as far as accessories go, but I repsect those who are. Heck, I even have a few Harley parts on my Indian! I enjoyed that link to the ford muscle forum. It was funny to see those guys ripping each other! Hey, It's a hobby, do what makes you happy!
