So investigation today update:
1) ignition switch cleaned up and put back together as per the PanteraPlace tutorial. Before and after. The black was actually grease through I can't imagine it helps with conduction.

2) tinned the ends of the wires where they connect to the loom connector block which seemed in good condition.
3) cleaned up the battery ground - wasn't too bad, but now it's shiney
4) swapped in a new Amp meter I had on the shelf to get a comparison - less wiggle on the needle, no wiggle when there are no systems switched on. The more is switched on the more wiggle - I think it's jsut a fact of Pantera life... and I think we all know that. Banjo connections on the red wire looked to have suffered from heat...
5) went for a drive, 10 miles maybe, all seemed ok, but died once at idle at the lights - perhaps it's more of a carb idle thing... as it fires right up. idle is highish anway so it's not slowing down too much and dying, it just cuts out randomly...
I might wire in an experimental hot wire directly from the battery to the coil via a simple switch - do I need a ballest resistor ? I need to check which coil I have in there. It could be a Pertronics Flamethower 3 as the car came with spares and there was an empty box for one.
