'78 R100s kill switch fried

That was my initial thought. But no, the poles are located same as the Panasonic LC-X1228P it replaced.

What other maintenance have you done? The position of the coils under the tank puts the powered terminals very close to the tunnel of the tank. DAMHIK.

Hmm. I did remove the tank to top off the brake fluid about a week ago while I was waiting for the new battery. ..

There's something very strange going on there. It shouldn't be possible for (any) current to get to the kill switch without the ignition switch on. Can't think of anything that would cause this issue unless there are two distinct faults, one short circuit and the other involving the ignition switch. I Really think that you n(or someone) needs to go through the electrics to find out what exactly is going on.

If the battery were to be connected in reverse, there would be an immediate and destructive short circuit but this would be through the diode board, which would be destroyed. I can see no reason why there should be any current flow through the kill switch, especially if the ignition switch is off.

Without the ignition switch being on and assuming the ignition switch is not faulty and is wired correctly, the only way I can see a live feed getting to the ignition circuit is via a fault in one of the other items that link in to that circuit i.e the buzzer relay and the starter relay. Only one of those items has an unswitched feed from the battery and that's the starter relay. So that's what I would check first. Still can't see how the starter relay would cause that but this is one weird fault and it will only surrender to a strict logical approach.
