Started, warmed up eng and then turned off all the lights in the garage only glow on the hole wiring was a small glow from the cap were i drilled hole in it to see if the rotor was out of faze years ago.
I have done this before, several time on cheep spark plug wires and they glow any where they got close to metal. The eng compartment was in complete darkness. Set there and let my eyes adj to the darkness and nothing except the round hole in the cap.
Thanks tjpatte!
