Charging,?.

[David.H]

Main battery negative earth strap goes to the body using the original point under the passenger seat.
I always used a single earth point for accessories on my rally cars, this used with relays for anything with a switch meant that electrical problems were happily non existent, even on 10000 mile marathons to Australia!
I have fitted relays for the dip system as the original switch on the column is tiny!
I will run a reasonably heavy lead to a gearbox stud.....with the isolater switch it is getting a bit crowded round the terminal post
In addition a strap from the block to chassis, although the system does seem to rely on the steel body as it's ground.The control box earth is a short lead to the bulkhead earth point.
One change at a time so I can see if anything works!
Perhaps we should treat a Seven like a fibreglass bodied car! I had a TVR Tamsin once and every wire on the car was black....Originally they had coloured tags by the terminals, but by the time I had it they had all gone beige! Mind you I never had a single electrical problem. OK the headlights went out occasionally. .......!
Thanks for your helpful comments.
