Hello everyone,

Is there a way of testing Speedo clocks without it being in car? I bought car 2 years ago and it came with a spare center Speedo and I was told the fuel gauge didn't work. Before I try to take it all apart just wondered if you could do anything with the multimeter.

Also anybody but seam strips on the edges with seam sealer inside them, just thought it would keep moisture out

Cheers ian

Try using an electric drill with a small square 'bit'.

For the seam strips I am planning to give the flanges a good coating of Dynax S50 before fitting them. I'm hoping it will creep into any small gaps and stop mositure getting in.

Thought of something on them lines also, just thought seam sealer would close it completely

My worry is if moisture got behind the seam sealer. Lately I have been dealing with that very issue under the boot floor, it has made a mess.

You can test the resistance of the Fuel Gauge. I have a number for that - somewhere !

That's what I do, but you need to run the drill in reverse.

Test the resistance of the guage.

As for the seam strips paint the car then fit the strips with the clips, a small amount of non silicon sealer at the top, then paint the sealer

Thanks everyone.

How do I test the resistance? I know with multimeter but what setting do I need it on, ohms?
And what sort of reading am I looking for?
Cheers Ian

Also thinking seam sealer might not be that good an idea!!!

I seem to remember a drill may not be fast enough. If you know of anyone with a metal turing lathe that should be fast enough.

My Cordless Drill on low speed is about 80 kph on a Moke Speedo.

Figures from exploring speedo error when driven by a lathe. We could set the lathe speed pretty accurately and work out the error.
