I saw several threads on what parts were needed to convert a flathead from 6 to 12 volts, but no part numbers. I ordered some parts from NAPA, and I'm hoping they work, because I don't want to ruin a fresh rebuild by cranking it excessively with no spark. I used '57 Thunderbird part numbers from a NAPA catalog: FA82 12 volt condenser ICR11 12 volt ballast resistor IC10SB 12 volt coil From what I've read, this should be all I need (besides stock 59AB ignition parts) to get it running. Does anyone see a flaw in this logic, or does it sound like a plan? As usual, I thank anyone who wants to share info.
All I ever do is replace the coil with a 12v. one with a built-in resister. Then you don't have the resister hanging out in the open.
I have a chrome coil from Speedway for a SBC (got it from the neighbor), a 12V resistor from Napa (unsure what its for), and a 12v converted generator. Good luck.
I just installed the same setup on my 1947 Ford with a 59AB flathead. I have been having trouble with the coil with a built in resistor and stock condenser.
If you are using stock guages, use a "dash power regulator" for a 1965 to 1968 Ford. Fords up until the late 70's I think had 6-volt guages, so they needed a kick-down. This one is easy and siunce it is designed by Ford, should be a good place to start. I have one on three diff cars.
Does anyone know what OHM the resistor needs to be? Im troubleshooting an issue with my ignition and accidentaly broke my resistor today! I put in a 5 OHM resistor and it started smoking on startup. Any ideas?
a buddy and i were just talking about this today. then i find this thread.hell im going in the right direction before i knew i was going...lol
Outside of having the generator converted I can most likely just go to the back shelf in my garage for the proper pieces. Outside of not liking dim headlights I'd probably leave it 6 volt and may still do so. <input id="gwProxy" type="hidden"><!--Session data--><input onclick="jsCall();" id="jsProxy" type="hidden">
The ohms would be in the NAPA catalog, but you don't need them. You just ask for a resistor for some model of Chevy with your coil...just say '68 Nova 307. They have said resistor in two forms...a replacement resistor wire for the harness, as used on most chevies in the 60's, and a separate resistor that can be used instead. Resistors oft smoke on first use out of the box...they get hot, and whatever oil or coating the factory put on there goes away in a few minutes.
Howdy I have used many internal resistor Coils in converting from 6 volt too 12 volt, only one ever gave grief ( it was boxed up wrong) what I like is not having the extra wire's and a porcelan block having too be mounted, and the volt drop for gauge's for ford trucks works very well also,good advice........happy motorin
I've been using a stock 6 volt flathead starter on 12 volts for over a decade with no difficulty. Works fine.
Does anyone have a part number for this? I think it would work on 6 volt gauges in my '41 Ford Truck If you are using stock gauges, use a "dash power regulator" for a 1965 to 1968 Ford. Fords up until the late 70's I think had 6-volt gauges, so they needed a kick-down. This one is easy and since it is designed by Ford, should be a good place to start. I have one on three diff cars.
This is the solid state version I used after having issues with the stock ford one. Has lasted 15 years so far. http://www.cjponyparts.com/scott-dr...regulator-improved-design-1965-1966/p/HW2880/
Thanks for the jumpstart on my project I appreciate the research and work you did. Do you happen to have any pictures? Sent from my iPhone using H.A.M.B.
Hello Sportsfans -- I am looking for a kit, less the alternator, to convert a 52 Ford truck to 12 volts. Have any readers purchased a kit, if so, who made the kit and how was your end result? I know there are some that have used a magneto as opposed to the alternator - I would also like any first-hand experiences there as well. Thanks.
no such thing as a kit, you just need the parts listed at the start of this thread. i assume you ment to say "generator" , not magneto, but any way, alternator or generator , take your pick. ford went to 12 volts in 56, so any regulator 56 on will work in your existing wire harness, then a 56 &up generator case with 12 volt winding will bolt on to your front mounting plate, and you now have a 12 volt generator.
