Thanks Steve, Its not a fuse as that would merely melt. What I saw was wreaths of smoke of something burning not melting. 

Vet Mem The other half would not know one end of a multimeter from the other, let alone buy me one. She is more into socks and underpants! I have three and a reasonable amateur understanding of how to use them.  Can't see how that would help as when I eventually get to take it to bits I expect to find some charred electrical component   Was hoping that the excellent forum would have an idea of what was likely to be burned out by 12 v shoved in the wrong spur of the key switch  It has to be an electrical component or wire and affecting the starting process.  My guess would be some thing that is associated with the spark generation. 

 

The multimeter was more to test the new start switch block compared to the old one before fitting rather than diagnosing the damage done by "slapping a new one on" and crossing ones fingers😉

Just look at what electrical kit resides around where the smoke was coming from...coils, starter, wiring and then check it out or swap it out. You could look at what the new switch energised that it shouldn't have, doesn't sound that nice...good luck.

Really helpful  Thanks guys. Makes sense. If weather is fine I will start to disassemble before going to Christmas lunch hosted for a change by offspring! Results to follow
