engine problem diagnosis help
and very happy to have another IP in the stable, one day when I'm bored, I'll install it an see if it's any good.
The one I'm running now came from a salvage yard, unknown but with a warranty for 150, and it's going great, so hopefully get lucky,
also gonna try my hand one day at doing the seals on my old pump that ran good before but crapped out. I think it's still good but needs rebuilt.
I like having the extra parts on hand that i've been accumulating, now got extra pumps, injectors, clutches, fuel pumps, and that's mostly all she needs generally.
Maybe I'll grab that trans and have it tested, the yard has a warranty so if it's as good as it outwardly looks, I can sell it, if it's bad, got a report card and a refund.
In any event, I have more to pull off that truck, and half my list I hadn't got to get, ran out of daylight.
I thought I was driving with no alternator, but somehiw my super redneck repair worked. One brush lead squashed, the other drilled and crimped, broken, wrong part, with a length of sil-fos jammed in, toothpicks hold the brushes back for install.
Zero changes I thought it would work, but I drove today and no discharge. It's still somehow working.
When I pull the pumps at the junkyard I pull em with the lines and they never charge but a few dollars more, I've got plenty of spares if any of mine break
I spent much time looking for a oem motorcraft alternator, and the heaviest nicest wires to hook up, when I found the idi, I was surprised, need another day to wrench on it, the jy is closed for the holiday. Gonna put that alternator in today when I get my ash up n movin'.
Donor was an early 90's lincoln continental, for the alternator and connector wires, the primary wire was sourced from a late 90's grand marquis with eyelets and fused links built to exact length.
I picked the 8.5 in large frame 130a unit clocked 12 o'clock apart, and fit is absolutely exactly as 2g 70a it replaced, perfect fit.
I took the slim fender washer from behind the stock pull nut and put it behind the pulley on the 3g, perfect belt alignment and case clearance.
The pics online varied in most cases from what I found in my 85 so just had to figure it out, but was pretty straightforward. I kept the stock alt harness because it backfed B+ to several yellow wires, doesn't hurt anything to stay hot, keeps old electrical routing unchanged, but clipped out where unneeded terminals were, kept ext voltage regulator, but it is now unused.
Fat wire went to the hot side of GP relay, the yellow went to the hot side of the start relay, which backfed by old alt harness retained to the other stock yellow wiring.
Green w/ red is pulling double duty now, from same color lead from near the external regulator. one to energize the alt as it's supposed to, and 2 it is now powering a 30a relay to activate an electric booster fuel pump, because this was hot on ignition and not acc.
I retained the small red ammeter wire that feeds through hot to the yellow wires in the stock alt harness, but clipped it's small yellow sister, that also was hot, to prevent burning wires or stock ammeter gauges because of high amperage.
The red wire has no outlet for now, but when I put in a volt meter gauge in the stock cluster, that yellow will be geounded to power that gauge.
It's running fine, no more grinding bearings noises from the old alternator. Though that 70a old bass turd was a trooper and earned my respect.
The installation went smooth and it is nice to have my axc fuel pump on that relay, I guess the alternator does what it's supposed to be doing so looks all good, I'm happy to have found an oe motorcraft that wasn't a rebuild, I will pick up a spare to have just in case, hopefully it proves as reliable as the old alternator.
I'd rather not worry about leaving it idle and getting warm, so put em' back on, it's Tennessee afterall, it can be 30 degrees one day, and 70 the next in wintertime, better to leave it on the safe side.

A fresh Rebuild will sometimes run a bit warmer until things break in a bit.
It never ever gets warm though with a fan and shroud, regardless of towing outside temp or grade, very happy with the rad mod, just maybe not as much capacity to idle without any airflow, and really, it didn't get too hot, just hotter than I could ignore and never worry about it.
I'm extremely pleased with the 3g swap and I'm sure you'll be too
