Need something answered here. I have a 6v coil and I pulled the coil wire off today and the end of the wire looked wet. I now some coils are oil filled. Reason I'm asking is I changed the coil out b/c my fairlane quit 2 times going up a hill. It will start back everytime but takes a few seconds.(longer than normal) Does this mean the coil is breaking down and going bad when thr engine comes up to normal temp. This is the coil I swicthed out will doing all that work to the car. It was a old one I had saved b/c I thought it was good. Sounds like time to buy a new one. Thanks Again

i have seen coil's break down and quit when they get hot. my old tractor had a coil that would not fire when it got hot.

 

Thats what mine is doing now. I quess the oil works as a coolant to.

scott, replace coil making sure it is mounted where it can get cool air flow. also, replace condensor!!! on 6-volt systems there are small, intense electrical spikes that fry condensor. for explanation of entire ignition system, go to, msn flathead forum- click on- rumble seat tips then flathead visions. scroll down to list and click on- ignition- read it all. this is an exellent source of information for flatties.

I don't know if anyone else will agree with this but I drove my 51 Merc for over 6 months with a 12 Volt Coil on it.
I only noticed it when I reset the valves as they were in need of adjustment, it was then I discovered the 12 Volt coil.
I replaced it with a 6 volt one and it ran the very same.
For what its worth to you if you have one handy try it.

 

Many 12v coils (the ones designated for use with external resistor) are really designed to work on lower voltages. The ballast resistor drops 12v ignition voltage down to somewhere around 7v. Scott, is your engine a stock '46?

 

exellent point! sometimes these units will burn out or even rust out. also, make sure coil is hooked up correctly. positve to ignition, negative to coil.

 

Also on oil filled, when mounting in the horiz. position, make sure the nut posts are at the 6 o'clock or bottom. Insures all parts internally are oil covered for longer life. Elevate, reposition or insulate from heat. chuck

 

'46 = pos ground

so neg goes to ignition switch, pos goes to points

(that may be what you meant?)
