Another part of the puzzle sorted.
Got my battery cables from Olly when he broke his car, but wasn't too keen on the audio fuse holder to join two pieces of cable and the overkill 3 ton connections, so saved some weight and improved the connections for a few quid by visiting vehicle wiring products in Ilkeston. Very helpful people and have everything possible for car electrics. There web address has appeared in my thread once but won't hurt again for anyone trying to sort electrics. Whilst there I also picked up an earth braid for the gearbox, some rubber grommets and a rivet gun

Yellow Earth Cable (The guy even used yellow heat shrink!), Battery lead now joined and heat shrunk, and last part of battery lead which bridges from kill switch to starter motor.

The offending HEAVY weight connections vs. A new light weight connection properly crimped on and heat shrunk!
