Yet another Pertronixs question

[Williboy]

Actually it’s a coil question
YES, I know the red wire from the Pertronix’s MUST go to 12 v,
But what about the Flame Thrower II coil + ????
Do you run 12v or 6v (resistor) to the coil???
According to the web site http://home.teleport.com/~cosa/vap/tech ... txhome.htm you run the pink resistor line to the coil.
According to the Pertronix instructions diagrams you can run 12v to the + side of the coil if you don’t have a ballast resistor Fig.2 ( non Ford) or run the resistor line to it. Fig. 3
What if I ran a 12v wire from the ign. to the coil + and connected my Pertronixs red to it there??
Is there any advantage or disadvantage in running a full 12v to the coil???
Is there something I’m missing, overlooking or don’t comprehend???
Thanks

Hi Williboy,

The short answer is YES. The FlameThrower II is designed to run on 12 volts. Run 12 to the coil and hook the Pertronix "red" lead to the "+" side of the coil. If you have a resistor in the line you can remove it. This will save you the trouble of running another line from the switch to the coil, i.e., if you remove the resistor you can use the existing coil wires.

The coil will generally run better if it has 12V. It's not like the original yellow tops that I don't think can handle teh 12V very well.

Personally, I run my flamethrower coil with 12V with no problems.

Look at it this way. More voltage to coil, more power build up and hotter spark.

The instructions from Pertronix are terrible. The connection of the PII should be the same as the Pertronix I. They tried to make ther instructions more clear, but I think they muddied up the waters even more. They should just bite the bullet, and specify in their installation instructions that it needs 12V. We know it doesn't "need" the full 12v, but for intensive perposes, just wire 12v and it will be fine. I don't know why they insist on keeping the 6v reistor wire crap in their instructions. It is a good product, but it has some of the worst instructions.
So after a lenthy thesis the answer to your question is yes. If you have run 12v to the coil, then you can just connect the red from the Pertronix to the + of the coil. That is how I did mine.

Bottom Line:
1. You can try the 6v wire. If it doesn't work, wire in 12v
2. Just wire 12v and be done with it (that is what I did)

Thanks for all the info.
I got that damn virus and couldn't log on for a few days!!! ( It's really good to have your girlfriend in IT!!!)
Meanwhile I called Pertronixs and they said the same as you all did.
That I can run 12v straight to the coil and to the dizzy.
I'm going to try to get time to hook it up this weekend.
Thanks again,,,,,,GLEN

Just an update and a FYI in case anyone wants to know. Finally got to work on the toy today.

I remounted the coil to the shock tower and ran a new 12v lead from my ign switch to the coil and hooked up my red lead there.
Everything thing went well untill I went to start it!!!
Cranks over but not firing!!! Hmmmm???

Double check everthing including voltage at the coil and still nothing!!!
Try starting it at the relay and it fires right up!!! Hmmmm????

Long story short... Ended up that when I hooked up my 12 v off the ign switch I went off the "A" accessories post. Thats 12v but not while starting.
Pulled out the Pink Resistor wire bullet connection crimped on a new connector and got my 12v there.
Now it's running great!!!

Hey Mustang66 - It's "for all intents and purposes" (just giving you a hard time)

Anyway - real question. What about a Duraspark 2? Do you want to run 12V to that as well?

Their instructions were so bad I ran my C-221 Farmall's coil on 6 volt for a year even tho the coil says 12V right on it. Much better cold starting on a motor known to be cold blooded now. As we have 2 motors with these on them I think it might be smart to get a spare, nobody seems to have them retail round here.

Yes. This is how my setup it laid out, unless you are using the stock 6V coil. All DS2 ignitions have a 12V coil, I think. So if anyone does the DS2 conversion, it would be wise to get the coil as well. This is sometimes over looked on various web site conversion descriptions.

Besides, in order to get a larger shark gap (which I think is one of the driving reasons to due this conversion) you need more juice in order to produce the arc needed to cross the wider gap, right?

How can I tell if I'm getting 12v to the coil?

with the ignition on measure the voltage at the coil from the switch.
