Was in bonny scotland last week on our bi-annual 5 day jaunt round the west coast. Got to Fort William first night, wet as usual, went to start in the morning, wouldn't fire up
Tried bumping it, no joy. Called AA, as my eight amigos rolled out of the car park waving goodbye 
Local recovery guy came quite quickly, seat was off and tried putting a booster on the battery. Would crank, but, no ignition. Took rear spark plugs out, all wet, dried them and even heated them up. No joy, done the spark on the cylinder head and found the spark to be weak...
Gave up, and got recovered home, some 14.5 hours later got home. Still starting issues, checked battery 12.45v and when pressed starter switch, the clocks dance like a cheap whore and no crank
Changed a spare set of coils I had as thought the rain over night might of affected them. Fired up, then over the last couple of starts eventually gave up again. Even tried shorting my starter solenoid. Nope, petrol pump primes every time. The initial recovery guy did give it a 20-30 secs on my starter switch with his heavy-duty clamps and booster on mind 
I have put an R1 rectifier on a couple of years ago and chopped out the brown and white plugs and just soldered the joints together. Any help appreciated. Oh, have the frame powder-coated, so have done an earth onto the engine block to my frame(not very thick wire though). May make a heavy-duty wire tomorrow, just incase...
Friend coming round manana to help swop over a partial loom swop. Have a full loom in my stores box 
Failing that, new solenoid and refit my old starter motor that has new bushes in....
