Normally when someones says to hot wire a coil they are saying to run a wire from diretly from the battery to the coil. But I would not do that with a front mount coil. I would wire it so that it still goes thru the ballast resistor. If I wanted to just bypass the ign switch, I would make a jumper with clips to jump from one side to the other.

To hot wire the coil run a wire from the non grounded post on the battery to the top of the coil. This bypasses the resistor and the ignition switch and helps diagnose lack of spark. This will not hurt the front coil if only run for a few minutes. I have purchased a several front mount Ns that were wired this way and not discovered for a couple of weeks. Still using those coils.

What problems are you having that would require you to hot wire the coil?

If hot wired and not run for say more then 30 minute or less not likely to hurt the coil. Ya if it was hot wired and run for hours yes the coil might fry

As HCooke say run a wire form the battery ignition side as non grounded side to the coil wire. That is one of the many trouble shooting thing done to find where the problem is

To be honest Bruce I'am not having any problem at the present time,I have done a lot of menchanial work on the three I have owned, even some new wiring (not a complete wiring harness)I'am a beleiver in if it isn't broke don't fix it.However at 78 years of age I though I should learn what was meant by hot wiring. I also own a 46 Packard and did do a new wiring harness on it , took about a year but finally got it correct (make a preacher cuss)finall I want to say thanks for all the help I have received from the post I have made especialy your 75 hints. Thanks again. Bob

" I'am a beleiver in if it isn't broke don't fix it"

Same here!

Which is why I asked the question; hotwiring the coil can get you in trouble!

BTW, if you can re-wire a 46 Packard, you could do an N tractor in your sleep.

My first car was a 1953 Chevy. It had a 6 volt system and to many miles. I ran a wire from the battery to the coil and controlled it with a switch under the dash. On those cold mornings that the old Chevy had trouble starting I would flip the switch sending better voltage to the coil. The old Chevy always started. Once it started I flip the switch off.
