Thanks everyone that’s given me some ideas to work on when I get home. BTW problems started after having the chassis welded at MMC. TIG or MIG probably hasn’t done it any favours.

If you haven't already maybe contact MMC and see if they have a replacement TSM they can give you.

So far as I know, are these the diodes at the instrument panel connection.
How to check if working correctly without taking the wiring apart?
Disconnect then fabricate needle point meter probes to pierce shrink sleeve. The diode end with gray bar is the cathode.

Hi Richard
Just tested the diodes and they are all good, now it’s blowing fuse number 2 as soon as the hazard lights are switched on, exactly the same as a dead short. Indicators don’t work at all now. I can hear relay’s operating in the TSM when the indicator stalk is used and the indicator’s flash for a millisecond.

Update…..
With the TSM out of the car fuse 2 does not blow, everything else works fine. Looks like the TSM has had it.

I just got a reply from Alister on my question if he could make a adapter cable from a 12 pin TSM to a 18 pin TSM.
He wrote if we could send him an 12 pin TSM he will have a look if it’s possible.
If the one from Dab of oppo need replacement it could be a good choice to send him.

I have a brand new 12 pin TSM in my spares kit that I would be willing to volunteer to the cause (as long as I get it back!)

What a god dam nightmare. I think I have finally got to the bottom of it.
After 3 1/2 hours of disconnecting and tracing wires, belling them out, testing for insulation resistance I found a fault on the near side front indicator circuit which when disconnected at the under bonnet multi plug seems to cure the faults. Further investigation revealed the self tapping screw holding the lamp unit into the housing was longer than it should have been and had punctured the lamp unit and had shorted it out internally.
Removing the self tapper cured all the faults.
All I have to do now is reassemble the car as it's in bits all over the garage.
A large whiskey and a rub down with a damp copy of The Bulletin I think is in order.
Thank you once again for all your advice, much appreciated.
