bring this up again, but all is quiet here.
When I found a nice AC WD45 a few years back, I switched it over to 12V. I found an old Delco tin can 12V coil here, and put that on. Recently I cursed myself by thinking how well it has worked. About the next day, it started acting up on me. Cutting out. Just like someone switching off the ignition as briefly as possible. Remove load, and it ran fine. The off periods were getting longer, so I quit. The coil stayed cool. I replaced the points and condenser, and also installed a new, generic 12V coil requiring no external resistance I had purchased for a job last spring, and then didn't use.
I guess I had assumed the old Delco coils with 12V embossed into the tin were all the same. But I looked at my D15, which is OEM 12V, with no resistor, and the three digit number on that coil is different from the one I had put on the WD45.
I'm guessing the old 12V Delco coil I had put on the WD45 was made for use with an external resistor.
