British Bikes / Re: TR6C wiring problem (continuation)

After the meltdown I switched to a 10A quickblow fuse which was fine but I didn't try the horn with it. Now that all is well I'm running it with a 16A type T (slow blow) which I guess is not far from the Lucas 17/35.
With the seat touching the battery neg, the fuse doesn't come into it. The circuit is battery neg, seat metal & frame, earth wire in loom from Zener mounting to rectifier stud and, then, from rectifier stud to batter pos.
If there'd been a single 30A wire directly from the stud to the frame that would probably survived; OTOH if it fused then the earth wire in the loom would have rapidly followed.
I've now removed all terminations to the (red) earth wires in the loom - circuit diagram is attached.
