I'm sure I have seen a mention of this before, but I can't find it by searching the forums. I have a new Lucas wiring loom, but the frame earth ring terminal is far too small to accept the bolt at the rear of the petrol tank. I imagine this is a common problem for others buying this loom. But what's the answer? Obviously putting on a bigger terminal, but I hate the idea of butchering a brand-new loom. Is there another, more suitable, earthing point with a smaller bolt, such as the rear mudguard/rectifier bracket? If I decide to put on a bigger ring terminal, my frame is newly powder coated, so should I strip the coating to bare metal where the terminal touches it? I think I know the answers, but am keen to know what others have done!

Any frame fixing point will do. Will the terminal reach down to the battery mounting fixing bolt?

As youhave correctly surmised, powder coating is a reasonably good insulator!

Personally, I would remove the small ring terminal and fit a larger one. If you do it properly, its not butchery at all, its just wiring. You must remove powdercoat if you want to make a good earth. Do it carefully and it wont be seen anyway, and if you can see a little of the bare metal once the bolt is tightened up, just touch it in with a little black paint.

I agree .the greater the area of contact the better.a little petroleum jelly will ward off the wet.

Running another piece of thicker wire from central point to to engine mount will also help a lot in cutting down high resistance joints.

Four now on the road and at least several in bits.
