12 volt conversion with a6 volt coil

2 fords in ny · Jan 3, 2010

I got a 52 ford 8n that someone else put a 12 volt conversion on. The tractor has the front mount angle distributer. i took her apart and cleaned her all up and painted her. When i put it back together she ran bad and the exhaust was getting super hot. Timing was all over the place. As a last ditch effort I changed out the 6 volt roundcan coil with a 12 volt coil I had sitting in the shop. She runs great but I am now worried about burning things up with the 12 volt coil. there is no resistors in line anywhere in this system. do I need 1 or should I just let her eat?

There's no way any of us can help you without knowing the primary resistance of the coil you are using OR the part # of the coil OR if there are any markings on the coil such as "Use with external resistor".

BTW, WHY did you title your post "12 volt conversion with a6 volt coil", then proceed to tell use you are using a 12 Volt coil? Makes NO sense!

Furthermore, a coil has NOTHING to do with late timing/hot exhaust or "Timing was all over the place."

You come across as a "bullshipper"!

You'll be fine...a 12volt coil requires no resistor...the 6 volt coil would require a resistor. Without it, it would send too much voltage to the distributor causing the spark to fire erratically and "burn things up"

what i said was it had a 12conversion that someone used a 6 volt coil with, and then I put a 12 volt coil in it. And I dont know what to tell you about the timing it was all over the place put in new coil and it settled down so take it easy buddy I was just asking if it was going to be a problem using the new 12v coil. Thanks bob I looked up the 12v kit in this sight last night and it said the same thing you did.

I meant thanks jeffalex2.

Bob you should relax a little. lol

"Bob you should relax a little"

Yep, you're right about that!

HOWEVER, simply changing the COIL wouldn't fix a timing problem, which is what you wrote! WHAT did you do to correct the timing problem?

"When i put it back together she ran bad and the exhaust was getting super hot. Timing was all over the place."

Jeff,

You might want to say that a TRUE 12 Volt coil (HOPEFULLY marked "no external resistor required) will NOT need a resistor. (These will have a primary resistance of 3 to 4 Ohms (or thereabouts).

HOWEVER, there's lots of coils being sold as 12 Volt coils that are marked (or SHOULD be) "use WITH external resistor". These will have a primary resistance in the 2 to 2.5 Ohms range (or thereabouts).

i did take the guts out of the dist. at 1 point and greased the weights. they didnt seem bad but maybe they were stuck. maybe with it not firing right it was missing with the timing light. maybe with it not firing right she was pumping fuel into the exhaust causing it to burn there and get hot. all i know is i put in the 12v coil and now she runs good.
