Is this a solid state voltage regulator? (1 Viewer)

[C6H12O6]

Looking for a new solid state VR for my '74. I've been reading through all the voltage regulator and alternator threads for a week and it seems that the Wagner W095-04 or Transpo IN554 were the recommendations, but Wagner no longer lists the W095-04 and Transpo has been sold and I can't find one anywhere.

I'm seeing the Standard Ignition VR470 everywhere, but it sounds like some of the VR470s are solid state and some of them were mechanical. They're about the same price on RockAuto as the LPS, but I'm confused how to tell if I'm looking at the solid state version.

The Standard Ignition website, as well as all the info I see online everywhere else, says that the "PC boards are encapsulated in epoxy" which sounds like that would be solid state, but then they all show this pic:

This doesn't look like most of the solid state VRs I've seen that are filled with epoxy on the bottom. What am i looking for?

Pretty sure that one will have the contacts inside the housing.
Why do you want a solid state?

More consistent regulation of the alternator's field current, (usually) better life, and when a SS voltage regulator dies, it usually just dies. When an old-school VR goes bad, it can fry other stuff. Not a total deal breaker, but I'd like to know what I'm getting.

That's the later 6-wire version. I need the W095-04 with the 3-wire plug.

Yes. Thanks for the input. Didn't mean to be dismissive. I'll try to call Wagner, but it's Sunday. Thought I might see if I could get an answer today. Looking at your link again, and digging into a list of the Wagner VRs from @Coolerman from eight years ago, that part (W095-06) is listed for 71-77, even though the 6-wire plug doesn't work as-is.

I'm probably way overthinking this. No news there. Just trying to get updated, current info. The general advice here of "use the search" is usually dead-on, but there hasn't been much on this topic lately. The part numbers recommended in the major threads here are from 5+ years ago and many of them don't seem to be readily available any longer.

I have the W095-10 on my '78. I had to order it directly from Wagner. Mr. Wagner himself took the order. I don't know why they aren't more readily available. They are great regulators and voltage stays rock-steady. You can change the connector if the regulator circuit itself matches the application.

 

[C6H12O6]

Thanks. I'll try to get ahold of them on Monday. I think any of the 3-wire VRs they used to make would work, but the current Wagner website doesn't show any 3-wire VRs any longer. Curious to see what they still have available.

The 6-wire options might even work, depending on what the other wires are for. I might just be able to splice in the correct connector to the three wires I need for my system. One is probably the idiot light. Maybe signals for other emission control devices on the later trucks?

I'd still love to know what's up with the easily found Standard VR470. Back in the 2012-2014 threads I've read, it seemed like it was a crap shoot whether you got the mechanical or SS version. Even customer reviews on Amazon say the same.

When I was growing up, "solid state" meant using transistors instead of vacuum tubes, and hence was mostly a marketing slogan to sell transistor radios. But I guess nowadays it must mean more along the lines of an integrated circuit using semiconductors.

Yes, I am old.

I had one that looked just like that. No idea on the brand, but I’d highly recommend them. The ‘71 GT6 I sold in 2006 never had headlights so bright before (the swapped in 50-55 amp electronically regulated ‘74 landcruiser alternator had double the stock alternator’s output).

I have a solid state regulator and 80 amp alternator I'll be listing soon for sale off of my 77. The vr was used for like 3 months. Pm me if interested .

Solid-state Replacement for Mech. Voltage regulator

 

[C6H12O6]

Just got off the phone with Bob at Wagner. The official word is that the older-style 3-wire plug voltage regulators are discontinued and not coming back. Wagner is, sadly, no longer able to get the parts for these from any of their suppliers. Their guideline is one million vehicles in service to keep things going. Apparently, once the word got out on sites like this that they had solid state VRs for these older trucks, 'MUD people called Wagner direct and bought them out.

Taken from an older post from @Coolerman:

69-72 FJ40 w/ Nippondenso 026000-811 = Wagner W095-03. This is the screw terminal regulator! NO LONGER AVAILABLE

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. NO LONGER AVAILABLE

77-78 FJ40 w/Nippondenso 026000-2950 = Wagner W095-10 = Transpo IN568. This is the 3 pin square green connector. One pin on top, two on bottom like an alternator connector. NO LONGER AVAILABLE

I'm still hunting down the Transpo stuff to see if they live on in any other form, but Wagner's advice was that if we find something that works for us, stock up. Nobody is going to be making drop-in replacements for much longer for these older vehicles. No money in it. Then, we'll be left finding other options with the right wiring and splicing our own connectors. It seems we're close to already being there.

On a related note, the Wagner guy said he'd be very surprised if any voltage regulators we find out there, other than very old stock, was truly mechanical. There was a switch to transistorized regulators, then full solid state regulators as the cost of copper went through the roof. I'd love to chat with the Standard Ignition folks for their view on the subject. I'll post up if I get through to somebody there.

Also, Bob at Wagner seemed to think that there were some real benefits to the older mechanical units. He agreed that the newer SS units were more consistent and less likely to cause damage if they fail, but that when a SS unit goes down, it's just dead. If you're stuck in the woods with a mechanical unit with stuck points, it was often something that could be fixed. Interesting take I hadn't considered.

 

[C6H12O6]

I just got off the phone with Standard Motor Products. It sounds like they don't make the VR470, but rather have it made for them. No surprise there. He said they are all "electronic" now, not points-style mechanical units. While there is still a bar on the bottom with a coil of wire around it that looks like the old points-style regulator, it is electronically controlled inside. If you're looking at a Standard VR470 and the coil bar is coated like the picture above, it is a modern, solid-state, electronically controlled regulator.

Hope that helps.

The Co that makes them still makes them, Wagner just reboxed ... I'm in correspondence with them now as they only sell wholesale to the Auto Electric business (not me). When I find out more, I'll let you know.

They have in stock both the W095-03 early type and the W095-04 72-74 type.

Maybe @Racer65 wants to stock ?

 

[Racer65]

Wow, Toyota was selling 27700-60080-84 for under 20 bucks last year. Now discontinued.

 

[Spike Strip]

This is the Co. They are still in production.
