Looks like alternator questions seem to pop up regularly.

For everybody living under a rock, 3G is the way to go.

Problem is, the FTE search function does not always turn up useful information and a lot of info came from RJM, which now is just a bunch of broken links.

First, there is a sticky that will help. Why it does not show up on a search is beyond me.

Next issue is, just what is a 1G, 2G, or 3G alternator? Help is here.

And here.

Converting A Ford 2G to 3G Alternator

There is a lot of variety in the 3G family including mounting system, frame size and capacity. Looks like the Taurus alternator is the favorite for F150 swaps.

RJM's demise created a vacuum for wiring harnesses. It's not hard to build your own with junkyard parts, or you can try vendors like Ron Francis. Biggest issue is GXL wire and properly fitted and installed connectors.

Anybody else have 3G info to add?

 

Well done! Good info.

I agree it is a shame that RJM went out of business. We lost a very valuable resource there, both in parts as well as information. Chris used to have all/most of the pics from the RJM site stored, so maybe he can provide Apis a link to those. Or, a link to the wayback machine where they are stored.

 

This link has been in a couple other posts.

Works intermittently for me, hope it will do for now.

 

packrad.net is as good a place as any, I guess; I use the wayback machine:

How are you supposed to attach the lugs with the Ron Francis kit?
Most people will not have even the hammer type crimping tool.
I personally like copper lugs and a soldered connection, or just purchasing the correct length cable from the LAP...
There's no fuse/fusible link or breaker in their charge cable?

I think it should be pointed out that the 8 1/2" C-C from the 3.8l V-6 seems to work best on V-belt trucks and the 4.9 I-6.
The 7" C-C from the 3.0 fits the serpentine belted Windsors. (the larger 144mm diameter 130A needs the cast bracket opened up)

There were a lot of side by side comparison photos hosted on the RJM/FFI site that were not linked in their 'alternator files'.
They don't seem to still exist in the waybak archive though.
