1 wire alternator wiring harness?

yes, there is a one wire conversion kit available, auto zoo might even have it but i k now that autokrafters does have it. it can be used on a ford alternator up to 55amp output. very simple to install, and very reliable. i know i have one on my falcon.

as far as i know the only way to get 100amp or more out of a ford alternator is to convert to a 3G or get a powermaster (GM style) the largest ford non 3G that i could find was a lincoln 85 amp but when it died i could not find the repacement, all the autostores only had a 65 amp unit. i even asked about rewinding the 55-65 amp units to 100amp but was advised against it since the small housing of the original ford units does not allow for proper heat dissipation. as a side note a 1 wire alternator is technically not as good as the standard ford seperate regualtor design. the remote regulator allows the altenator to maintain a more consistant output. it also does not require reving the engine in order for the alternator to "sense" that it needs to start outputing on start up.

Powermaster FTW

140 amps and a pounding stereo and it still charges like a champ :woot:

Depends on which alternator you use.
The simplest, though not a "1-wire" is a big-body 100 amp 1G alternator. Found on 70's Lincolns, and big Fords like mentioned above. These are larger and sometimes require a longer alternator "adjuster" bracket, sometimes they go right on. Instead of "post" terminals on the rear, they have two "blades" on the top for the "S" and "A" connections. Older Mustangs don't use the "S" terminal so all you have to do is cut off your circular connector for the A wire and crimp on a female spade conector. The alternator will hook right up to your existing regulator though it's best to upgrade that to a 70's elcetronic regulator while you're at it. I have one of these setups I swapped onto my F100. I plan to replace it with a 3G but the alternator just refuses to die so I'm letting it be.
For 3G swaps you need a plug-in. I like to rob the short harness from 94-8 V6 Mustangs because they unplug from both ends. They work from Tauruses and such too but you have to cut wires to get one.
Installation goes like this http://home.earthlink.net/~ehicking/mechanics/3Ginstall.jpg

2G's aren't very interesting, they're just 1G's with internal regulators and not much of an improvement. I recently pulled my good, but stock 2G off my Bronco and swapped in a 3G. My volt gauge now reads 12-13 volts all the where under full load the 2G would let volts drop to 10 or even 8. This swap is described here.

The usual "Powermaster" one wire upgrade is done using a modified Chevy alternator. Thes efolks here don't seem to think that's the best idea. http://www.madelectrical.com/electrical-tech.shtml Look under "1 wire vs 3 wire".

I called Summitt, got the correct part number and was shipped a Powermaster 100 amp 1 wire for my 65 289. I had to swap pullys(both included) and it bolted right up. I used the original heavy wire back to the positive post on the solinoid (sp?) and hooked up the guage wire and it works fine.
