I spent several hours chasing a no start / electrical problem. I previously had found the hot wire from the battery to ignition had worn through and shorted out. I replaced the wire and it turned over but didn’t start. Checked for voltage to the HEI distributor. 12.4V I thought maybe the module was bad so I took the cap off. Rotor looked like someone took a bite out of it.. a chunk of the rotor was MIA. I went and got a new cap and rotor and put them on. Nothing. Swapped coils- nothing. Swiped the module out of my ‘71 so I’d have a known good unit.Nope. Finally pulled the condenser out of a spare distributor and put that in. Bango! We have fire! Must’ve had that cap off 20 times today.
Still no idea what happened to the rotor and can’t believe that the bits weren’t inside?
