That tells me, you have the volts but, no amps. That would be a bad connection or deteriorating wires.

Found the problem. It is the tail light socket. I had the other dual filament wire set up wrong (cheap chinese light). Now it works with any light. New (used) OEM socket on the way.

Soldered a new ground wire into the current tail light plug and everything works There was also a secondary problem with a bad connection in the license plate light. I think this cropped up after I moved wires, but this is fixed. I have a new tail light socket on the way. Meanwhile, the old Kat is up and running, very well I might add.
