Later transistor kienzle clock repair?

Forensic investigation Graham - fantastic

Graham has risen to highest kudos in the fastest time so far .

Many stags no longer seem to have clocks fitted these days .

They often get replaced with a worry - gauge!
Often means one eye devoted to temperature, the other for oil pressure & not much left for the road

Still hoping for pictures of these clocks.

I do have two pictures from another source.

One of an apparently NOS black bezel Mk1 Stag clock with no 12, 3, 6, & 9, on the face. I have a used one of these in my box of bits that is exactly the same. It's a late 607b mechanism inside, which I think makes it very early 1970s. If mine doesn't work, I'm sure I can make it.

The other is a black inner and chrome outer bezel clock in an early Mk2 Stag. That is a 617a mechanism clock with squarish plastic hands and a yellow sweep. That should be a bit later, I think, from the mid 70s. The quartz one I am building looks nearly the same - I've had to use a new glass, so that's very slightly different.

Hence the benefit of a combined oil & water gauge . Clock was replaced with a no-name quartz for ~£35 which keeps reasonable time following a failed attempted repair to a Kienzle with a 1-piece moulded case.

I have 2 clocks the one in the car with the orange hand blows the fuse when connect instantly, the other one is to large to fit a stag, was told I could swop the innards ?

WRT the larger one: the mounting lug behind 12 o'clock and the black bezel and two screws in the face say it's from a Rover P5 or P6 (not sure about the P6, they may have all been chrome bezel ones) of about 1965 or 6. I'm told the black bezels came in 1965 and the screws disappeared about 1967. It will light up blue.

The innards of the larger clock are the 607b mechanism; the smaller clock has a 617a three-handed mechanism. It might be possible to fit the 607b into the smaller case - the power spades and the three mounting holes are in the same places. However, the Rover clock's face and backlight filter (if it's a plastic insert, not paint on the tin) won't fit in the smaller case and the Stag clock's face and backlight filter won't fit on the 607b mechanism.

Also, I've not seen one fail so that it shorts the supply to earth - not even the one I had where the solenoid coil had burned out, which they aren't supposed to be able to do. So I assume you've put some effort into checking the wiring to the clock before considering pulling it apart.

If it is the clock, then the problem, as with all these clocks, will be getting the bezel off. It's easier with the plastic case ones, but where the bezel is roved over the flange at the front of the metal cases, there's always a risk in levering it off, i.e. the bezel can split. But if it will come off, then you can get a 617a mechanism from an early 70s Dolomite or P6 clock - just be careful if you get a Dolomite one that it isn't one of those electromagnetic ones I disparaged before. The power and earth spades are at right-angles on the EM clocks, not parallel like on the 617a.

Thanks very much , will have a read through this thread and the other thread again and get it sorted in my head

I did work on a stag that was blowing fuse 1 .
Not saying you have made the same mistake…. But in that case , the owner had put the clock feed onto the earth tag.
wierdly, the car had run like it, then started blowing the fuses.
took a while to find.
