I am in need of a constant voltage regulator, voltage reducer, for my gauges for my 1968 Datsun 1600 Roadster. Does anyone know where in the Phoenix area I can find one?
Thx Special-K

There is a cheap and simple fix in the tech wiki. Pat

Is your regulator missing or just not working? If not working, some have gotten them going again by cleaning up the ground. There should be a small wire under one of the tabs on the back side that hold the case together. That is the ground wire, clean up that contact.

@unklpat Is this the Tech Wiki article you're referring to ?(see link below)
http://www.311s.org/pmwiki-311/pmwiki.p ... oltRegFix
If so, I notice that the eBay link to buy a Voltage Regulator in @DEVO 's writeup is no longer valid.
Maybe someone can post here specifically what kind of Voltage Regulator is needed and maybe even a new link to buy one.
There's also a paragraph in this article:

I have no clue about this electrical stuff yet.
Good luck,

Thanks everyone, I will try cleaning the ground wire. If that doesn't work, I'll ask a friend of mine to read the wiki article and see if he can do what it says. If that doesn't work, I'll continue trying to find one. Special-K

There is also a Datsun wrecking yard in your neck of the woods in Peoria, AZ. He sells Datsun parts on EBay and has a lot of Roadster stuff. I believe his name is Scott. Here is an EBay link to his EBay storefront:

I just soldered in the IC, and let it dangle. If anyone wants to crawl under my dash, so be it. If it fails, I'm $3.00 away from fixing it. Pat

I have a 67.5 with original regulator. If you take the cover off you will see the wrapped wire coil and a brass connector/ grommet . This is a very simple Printed Circuit board. I took a stranded wire I had around and soldered it from the grommet to the PC run. That run can handle quite a bit of heat. Re installed and all gauges have worked great for last two years.
I will say I am EE and a tech so this seems easy to me but your results could differ

The problem seems to be the contact with the case on the ground side. The IC solves the problem as long as the ground is maintained. I tried the "keeping it in the case" method, and decided to just let the IC dangle. Pat

Thanks Pat and Kevin,
Before I install my interior and dash, I plan on "preemptively repairing" my Voltage Regulator, so I plan on trying a solution like you guys are talking about -- but forgive me, I don't know s* about much, and even less about electrical.
So... "IC" means "Integrated Circuit"? Which is the actual voltage regulator, like this that Devo posted?

Kevin, any chance you have photos?
Thanks.
