Anyway here is the solid state voltage regulator I've just bought from them for my 1979 BJ40 through REPCO here in NZ. (REPCO I guess is abit like NAPA in the States.) Cost me $86NZ but we're used to "paying through the nose" in this part of the world. (The cost of living in paradise :D)

But hey, $86NZ= ~$45US, so it's really not all that bad. :D

I'm studying abroad in Wellington right now, and the exchange rate is kick ass - as well as the rest of the country. :cheers:

So, if anyone wants one of these suckers, let me know and I can pick a few up and bring them back with me to the states at the beginning of May.
 
OK, I'm on the hunt again. My alternator is sometimes putting out over 15V, and I have several things in the truck that are unhappy about it. I pulled the mechanical regulator and it *seems* to be putting out about 13.8V, in my simple test: I hooked up a variable PS to the IG and Gnd and measured the output on the third terminal as I turned up the voltage on the PS. The points started clattering and the F voltage stays below 13.8V.

I admit that I don't know what I'm doing. ;) But I'm learning.

So I used the Wayback Machine to find the contents of the link in post #27:

I just replaced the old points type voltage regulator on my 1968 FJ-40 with a solid state unit. I had been wanting to do this for a very long time, but never found the correct part number for a solid state unit. After a lot of research, I found the part and installed it last night. It works perfectly.

Buy either a NAPA VR1001 or a Standard VR128 voltage regulator. This is a solid state replacement for late 1960's Chryslers, it replaces the points type regulator in those cars. The pigtail on the regulator connects to ignition, and the stud on the regulator for the field. The "E" from the alternator just goes to a ground, I used the bolt that attaches the regulator to the firewall.

I used a VR128 and if the holes had been about 1/16th of a inch farther apart it would have bolted up to the firewall holes for the old regulator, as it was, I just used my Dremel tool and make the holes just a little bigger.

This is a very easy upgrade, it took me about 15 minutes. No more overcharging or very erratic output from my alternator.

(Oh look, it was already stashed here: http://www.ih8mud.com/tech/voltagereg.php)

The Transpo URL listed in post #24 has also changed, but http://www.waiglobal.com will get you to the right place.

Transpo still don't list a direct swap for the 27700-40010-84 that's in my 7/69, which has screw terminals. But I have to say that the
IN554
looks like it has the correct hole spacing. I wish I knew what "B-Circuit, E-F-IG Terminals," means ... the molded plug has 3 terminals, and then there's the extra barrel connector ... I'm sure those are 1/4" terminals, so it would be easy to change out on my existing harness.

The overcharging is suspicious, and the first thing I'm going to do is try cleaning up the terminals - maybe a bad ground or bad connection is causing the voltage that the regulator sees to be lower than what is coming out of the alternator... mysterious.

Funny, I was researching regulators again yesterday and ran across this information: I have condensed it down for the MUD crowd. ;) I don't know if these are solid state or not but this gives great connector information for anyone searching for the right regulator.

Wagner Regulator Cross Reference for Nippondenso Regulators

I emailed them and got a response from the president ;) that the 1971 screw terminal version for my truck is in stock and the price is $59.80.

69-72 FJ40 w/ Nippondenso 026000-811 = Wagner W095-03 This is the screw terminal regulator!

73-76 FJ40 w/Nippondenso 026000-2370 or 71 = Wagner W095-04 This is the 3 pin square white connector. One pin on top, two on bottom like an alternator connector.

77-78 FJ40 w/Nippondenso 026000-2950 = Wagner W095-10. This is the 3 pin square green connector. One pin on top, two on bottom like an alternator connector.

79-80 FJ40 w/Nippondenso 026000-2960 or 3190 = Wagner W095-11 or Wagner W095-06. This is the 6 pin oval green connector.

81-84 FJ40 w/Nippondenso 026000-4050 or 4051 = Wagner W095-18. This is the 6 pin round green connector.

They also list the following:

71-77 FJ40 w/Nippondenso 026000-2432 = Wagner W095-06. This is a 6 pin square connector with the .250 pins. (Like a wiper switch connector)
 
Thanks for the regulator info update coolerman, much appreciated

Very cool - thank you Coolerman
 
OK ... my local suppliers are all failing me. Can someone here tell me where I might acquire one of the Transpo IN554 regulators or the Wagner equivalent? My local starter shop, which has always been good at this before, has come up dry - and the NAPA stores around me have gotten stupid and can't find anything if it's not in their computer.

did you try these numbers?

Wow, what a flashback, that is my post from years ago. After switching to the regulator I mentioned, I never had another problem. I pulled it out just a week or so ago when I started my V8 conversion. I just checked the date of the post, it ran for 7 years without a problem.

Also, let me apologize for the 404 errors from a couple years. :) I have changed a lot of things on my website.

Here is a picture of the regulator from my post. This is the same one I installed when I wrote the post, and just pulled last week.

Anyone have any information on what regulator would work for a BJ-45 (3b, 12v)? I looked through the wagner catalog but they only had for the F models.

If it is a 6-wire regulator with a rectangular connector (as opposed to a "round" connector) then use either of the following:

Transpo IN551 (available in the USA)

or

OEX RGX2032 (available from Repco in Australia or NZ)

Both of these are solid-state and "simple plug-and-play replacements".

I am not aware of any of the old-school electro-mechanical units being sold nowadays for this application.

It's not one of the ones in http://www.wagneralt.com/catalog/books/W2008-09.pdf, on page 23/46? There are a couple there with 6-wire rectangular connectors.

Thankyou Chris.

I've never looked at Wagner products before but you are right!

The Wagner W095-06 is also suitable for Jaymundy's application I believe.

Edit: Interestingly - The transpos IN551 crossreferences to the Wagner W095-02 and not the W095-06! (But I still think the 06 is the safer bet.)

However I suspect that Transpo IN558 and Wagner W095-02 are alternatives that would do the job! In fact I've wasted so much tome this morning looking at stuff that I could give you hundreds of crossreferenced alternatives ...(including NAPA numbers that seem to be favoured in the states ie NAPA VR528 and NAPA VR529).

I sent a note to Wagner, asking for details about the W095-04, thinking that I would be able to mount it up where my mechanical unit is and change out the connector.

The president (!) sent me a reply, and informed me that the photo of the W095-03 is wrong - they are now shipping a solid-state version! So I ordered one up. It will be a few weeks before I can get to my FJ40 to do the install, but I'll give you a photo now. I'm quite excited ;)
