Early 92 Griffith Speedo - Made by?

[geeman237]

Who made the early 1992 Griffith speedometers? Stewart Warner? If so, are they repairable?
Tried a new transducer/sensor, no luck. There is continuity in the wiring from the transducer/sensor to the speedo head, therefore suspecting speedo internals perhaps?
Anyone got a working spare speedo?

Thanks

If yours is the black bezel type which sits flush to the dash and starts with the needle at the top then yes, it was made by Stewart Warner.
They do come up occasionally - I have a spare - so keep your eyes peeled. Alternatively there are threads on here about repair or even new copies so it's worth using the search function at the top of the page and stick Stewart Warner in the search box.

Try Warren at Topcats - he has a contact who still can repair & calibrate these devices - fixed mine on the pre-cat I've just sold - good job not to expensive

Thanks for the info. A couple hours were spent on forum using the search option. I think I have things clearer now. What I gleaned was.....

Very early 92 Griffith 4.0's only had the speed sensor on the LT77 gearbox, and nothing on the rear diff.
The speed sensor can be either a 4 or 8 pulse sensor.
I am not sure how you can tell without testing the car setup. You do need an oscilloscope, or at least it helps a lot.
The 8 pulse are very hard to find, if at all, and not too reliable. Cost about 100 GBP if you can find one.
Stewart Warner speedometer repair is hit and miss, with Speedy Cables maybe having a solution, but not always a speedy service.
The IC inside the speedo head is a CS289 chip which can be replaced and that part itself isn't very expensive.
I'm in the US and called Stewart Warner about aftermarket support. Zero chance of that it seems. They don't even have appointed service supplier etc.

You could try ETB: https://www.etbinstruments.com/

They repaired/refurbished my speedo and made a fantastic job of it. Done and returned within about 10 days as well and about £50-60 from memory which I thought was very reasonable.

Thanks. I looked on their website and in the FAQs they say they only work on VDO instruments.

I'd give them a call. My speedo was the one out of the Griff so it certainly wasn't a VDO.

Problem solved. A new 4 pulse transducer and bit of wire wiggled kicked the speedo back into life.
