Re: 1934 1101 coil problems, HELP!

I don't drive my '34 Eight that often, though I have driven it about 40,000 almost totally trouble-free miles over the years. Recently I had to replace one of my Bob Connolle repro NE coils due to a failure of the primary lead at the coil base. Of course he made good on it immediately.

I recommend picking up a universal 6-volt coil from NAPA, and one coil at a time while leaving your existing coil set mounted, just bypass first one and then the other of them with the new NAPA coil. In short order you should know if your problem was a coil, or elsewhere.

You might also check to see if the primary ignition feed wire to the coils (inside the steel armoured cable) has been replaced. If not, almost certainly the insulation is crumbling and you could be experiencing intermittent shorts within the cable as it grounds out on the shield. This should be very obvious by watching the action of the ammeter while the problem is being experienced. It's not possible to just bypass this coil feed with a jumper wire without removing the coils from the cylinder head but if you're in doubt about the quality of the wire inside the steel shield, it may be worth the effort.
