Gary Lewis Posted February 9, 2019 Author Share Posted February 9, 2019 I do see a listing on eBay showing a Leece Neville fitting '88-'92 7.3's But that is nothing like a 3G. https://www.ebay.com/itm/Alternator-NEW-Ford-F250-F350-7-3L-Diesel-1988-92-w-7706J-7706JA/282856215823?hash=item41db8b550f:g:jI4AAOSwZR9ajRqQ&redirect=mobile I think the best way to identify the 'correct' 3G is by its Lester number. That way you can apply it to any manufacturer. Yes, I agree that the Lester # may be the way to go. I can cross-ref from the part # to the Lester number on DB's site. And, speaking of cross-ref, our Interchange page shows two alternators for the '92 E-Series w/a 7.3L" 92-92 8CYL, MOTORCRAFT, 100AMP, 7.3L DIESEL F0PZ10346CX 88-97 8CYL 7.3L LEECE-NEVILLE,165 AMP F4UZ10346AX The Motorcraft is probably a 2G.

Gary Lewis Posted February 9, 2019 Author Share Posted February 9, 2019 Ok. Here it is. https://www.ebay.com/itm/Alternator-ACDELCO-PRO-Reman-fits-1992-Ford-E-350-Econoline-Club-Wagon-7-3L-V8/401694122114?epid=76533411&hash=item5d86d5e082:g:b6IAAOSwXSJbIpqT&redirect=mobile Jonathan is vindicated! Good find! But I don't see the Ford part number. Am I missing it? However, I did see that you can pay $29.99 for a 1 year protection plan - on an item with a lifetime warranty. Somewhere I have a sound effects LP where a guy walks up to the customer service desk with something that has a lifetime warranty. He says "It failed" and you hear a pistol cock and fire.

Ok, I need to add that to the spreadsheet. Thanks. I'm headed to bed (I know it is later there) so will do it tomorrow. Link to comment Share on other sites More sharing options...

On the Interchange page I cannot find those #'s. Here's what it shows for 1992 E-Series: 92-92 8CYL.MOTORCRAFT.95 AMP F2HZ10346BX 92-92 8CYL, MOTORCRAFT, 100AMP, 7.3L DIESEL F0PZ10346CX 92-92 ALLCYLS..MOTORCRAFT, 130AMP-EXC.

OPTION PACKAGE 92-95 6CYL 4.9L MOTORCRAFT, 95 AMP F6PZ10346HA DB doesn't show most of the BB part numbers, and the one it does show has a serpentine pulley. And, from what I can find, all of the ones that would fit a 7.3L have the 3-point fixed mount awa a serp pulley. But their #'s don't match any of the ones in the Interchange. I am CONFUSED! What am I missing? But, on a positive note, I've formatted the spreadsheet differently to make things more obvious/intuitive. That's 'cause I asked my wife what she understood from the previous format, and she misunderstood what was intended. So, I revised it and bounced that off of her. See what y'all think.

Steve83 Posted February 9, 2019 Share Posted February 9, 2019 So, that's the one for the '92 E w/an IDI? And yes, an ammeter that could be left in place would be cool. It would probably be digital and use a very small shunt. Shunt 50A, cheap display https://www.amazon.com/dp/B00P0W63PY Shunt 100A, big display https://www.amazon.com/dp/B07KPXVNY5 Inductive 200A https://www.amazon.com/dp/B07B4CWKRJ But I think they're all unnecessary distractions. A voltmeter & ALT light are sufficient to monitor the charging status. Link to comment Share on other sites More sharing options...

By the way, did you see my link to your clocking instructions in the draft 3G page? It is about half-way down on the Wiring It tab, under A Word On Clocking. Just want to make sure you are ok with that. All - Still looking for feedback on the whole thing, but especially on the choke discussion. I see no reason to have it because the 3G supports an e-choke off the stator wire just like a 1G does. So, is there any reason to keep it? Link to comment Share on other sites More sharing options...

I see no reason to have it because the 3G supports an e-choke off the stator wire just like a 1G does. So, is there any reason to keep it? You're welcome to link anything. Yes, I'd either dump the whole discussion about the 12V choke heater; or just mention that some people do it, but it's NOT necessary. Also: the indicator light doesn't excite the alternator - the 12V coming from the key just tells the VR (via its I pin) to turn on, whether or not there's a lamp or resistor in the circuit. All the electricity for charging (exciting) the rotor windings comes through the A wire. The lamp is only used when the VR detects a fault, and grounds the I pin. The resistor is only there in case the bulb burns out, so the VR still gets the 12V "on" signal. ...and I noticed a few typos... But my mother psychologically scarred me as a child with proper spelling & grammar. Link to comment Share on other sites More sharing options...

I vote to leave the 12v vs 7.5 v electric choke discussion in, maybe even with its own tab, with the confirmation that it's not a functional concern. There's a lot of back of forth on the subject in other forums with conflicting advice. The pages on this site are distilled into "fact" & verified function, and I would guess others will come here to clarify & would appreciate seeing it addressed.

Steve - Good points on the light/resistor. I didn't write that and will admit I didn't look all that closely at it, but I'll edit that part. And, I'll try to find the typos, but if you see some please point them out as I can use the help. Mark & Steve - Good points on the choke as well. I like the idea of a new tab and moving it there, maybe with a reference to it in the Wiring It verbiage. Let me see what I can come up with.
