Friends - Went to time my 51 w/ 235 and my old early 80's Sears induction timing light wouldn't do much but flicker. Went straight to battery with pos/neg leads per the instructions, and put the induction clamp on #1 plug wire. Figuring the old light had died so I bought a new Sears light, hooked it up the same way, now I've got two timing lights that don't work ..... Dist is stock but converted to Pertronix and the plug wires are new'ish. Any ideas would be appreciated. Bug
