Been having trouble signing onto the forum.

Found and fixed at least one problem! The Smiths regulator/shunt was touching a contact behind the dash. Found it as I was tracing wires with the Gauss meter and the CB stayed on after I'd tugged the ground wire I'd attached to the Smiths shunt case. Taped up the leads and got tach, fuel gauge. Reconnected the ignition light and it works as it should!

Of course my paranoia is that I caused that short by removing the Smith's shunt from where it was mounted (it couldn't short the way it was mounted, but I couldn't remount it in the same place with the dash in place). That means there's still a latent short somewhere, unless it is the pink wire? (No I'm not reconnecting that until I get some joy out of having a tach and fuel gauge again!)

Thanks for all your help! Will keep you posted.
