I bought a clock cluster set from a member on here and unfortunately the speedo doesn't work. It was taken from a scrapper/doner car. All the other guages work perfectly.

 

I did a search here and most suggest resoldering the dry contacts. As I know nothing about the circuits and contacts on the back of the clock, what type of professional should I bring it to check the contacts and do whatever soldering that is required. Its a 300kph clock and I'd hate to bin it as I was looking for one for quite a while. In fact it was my plan to get the white Led's done on this, with the Pod's etc over the winter with Groover (if the service will be still offered then).

 

Also has anybody any other suggestions.

Hi Mate, the service is ongoing so dont panic or worry, anytime and whenever you are ready.

 

Back to the speedo board. To be clear from the onset, the speedo clock needs to be taken out of the binnacle to get to the speedo board. Its fairly rare that the contact sheet on the back of the dash is at fault, but still worth checking for any burns or deep scratches in the copper tracks of the contact sheet.

 

On the back of the speedo board you will see several components which are lettered ie, the main speedo resistor is positioned at R10 and its around this area that you need to check first for dry joints, although they could appear anywhere on the board, this is the main area that the signal passes through. Dry joints will look dull or on occasion a crusty film. First spray some electrical contact cleaner on the board and use a soft toothbrush or small paint brush to aid cleaning. The contact cleaner can be bought from Maplin for about £4.

If you have a magnifying glass, try to take a close look at some of the tracks around the board and the ones that dont look too shiny ( bear in mind probably most of the tracks wont look too shiny, its knocking on for 20years old) run some solder onto the tip of the iron and trace the track with the tip of the iron, adding new solder if required.

 

It can be a bit time consuming or frustrating, but worth taking your time and dont prolong the heat in one area for too long.

If in doubt about doing it yourself, any electrical repair shop or video repair man will be able to do it for you.

Thanks for that Groover. You have given me some pointers there, so let the fun begin....:blink:

Hell I can't believe it is approaching two years since I purchased those clocks and never did any soldering on them.

 

Groover if you read this, and you are willing, I'll pay you extra and get you to do the soldering with the LED's. Are you willing? Please say :yes:

 

I'm going to use the ZED this summer. It bordering on criminal that I haven't done any more than a couple of hundred miles since I bought it a few years back.

Hi Bud, yes no worries i can take a look at it for you. email me on graham.jones@hotmail.co.uk and i can give you my address.

 

 

Cheers

Graham
