Hi everyone, 

 

I had a couple of questions regarding switching from 2 clocks to 3 clocks. 

 

I noticed the loom plug that plugs into the back of the clocks is different and is missing some connectors. Is it possible to remove and re-pin this plug? 

 

I was also wondering if there is a good way to repair an old PCB? I can't really afford to get a new PCB from Minispares at the moment (our exchange rate makes it a bit pricey). 

 

Regards,

 

Vinay

I've repaired these PCBs before. If you can see a break in the circuit tracks you can bridge it by soldering a wire over the break (Or just solder the break if it's a crack). You'll have to scrape away the insulation first to get a good contact and then apply a bit of epoxy or something to insulate your repair.

I don't remember the plugs being different? I thought they were a straight swap? (And another un-used wire from the coil waiting there too).
At least that's the case on the late 80s minis that I have upgraded to 3 clock, if I remember right.

Thank you. So the connector is missing 2 pins:

 

and the PCB has two extra wires compared to the 2 clock clubman ones:

 

The PCB has a few places where the connections are broken:

 

so, I would need to scrape off the ends and add solder? won't the solder melt the plastic PCB?

What about trying that product used to repair rear window heated grids? It is a conductive paint applied with a small brush to bridge cracks and breaks in the original current tracks of the glass heater. Should be suitable for the large conductor paths on the pcb.

I've never seen it before. Do you perhaps have a brand name I could look for?

Thank you! Going to check for this locally!

Did the rear window conductive paint work? I’m thinking of changing the order of my three clocks so the speedo is in the middle but ŵould have to run a wire/conductive paint to the Rev counter for the light... cheers!
