"OK! Ladies and Gentlemen!
I NEED HELP!!!
I am installing my new Flame Thrower coil that I purchased with a Petronix EI. The present setup that I have now is shown below in the schematic. The coil has a ballast resistor that I am taking out. Three purple wires 12volt switched and the red wire from the Petronix Ignitor EI module are connected together and plugged into one side of the resistor. On the other side of the resistor is a brown wire that connects to the positive side of the coil and then goes into the engine harness and disappears. The negative pole on the coil has the black wire from the Petronix EI and a Grey wire I think that is for the Tach. Now here is the million dollar question... In order to wire this corectly and to remove the ballast resistor, Am I to take the resistor out and connect the three purple(Switched 12volt wires)with the red Petronix ignitor module wire to the brown wire that was on the other side of the resistor? If I do that will that damage anything that is on the other end of the brown wire where ever the friggin thing goes? This I think just eliminates the resistor and connects the 12v purple switched wires to the Positive pole on the coil. I tried to connect the new coil and just remove the resistor without plugging anything together and the engine did not fire. Is connecting those purple and red wires to the brown wire on the positive pole of the coil the correct way to go?
As always you guys are a Great Help!!!!

"Well, I keep looking at the schematic and I think I got it. If I just take out the ballast resistor and connect the two wires that were on each end of the resistor together then that should give me the 12 volts needed at the positive post of the coil and it should work. All I am doing is bypassing that resistor and connecting the wires together.
What do you think?"

"OK, first get this file and go to page 22(20).

There you will see the wiring schematic for the AQ231A (yes, I know yours is the B, but the wirings are supposedly identical). You want the final drawing to look like the one in page 21 (19) for the AQ205A. In your drawing (page 22) you can remove the wire that goes from the starter solenoid R to the side of the resistor that goes to the + side of the coil. This wire was installed to bypass the resistor at start-up time (so that the coil gets higher voltage and gives a stronger spark), but you don't need that anymore since you are upgrading to a 12V coil (1.5 ohm) and to electronic ignition. Then, remove the resistor and connect together the wires at the upper side of the resistor (in the drawing) to the + side of the coil. Then, you are done and ready to go."

"John, your assuption (which you wrote while I was writing my response) is correct, but you won't need anymore the wire going between the starter solenoind and the + of the coil. Then, after you remove the resistor, all the wires at the 12V side of the resistor should go to the + of the coil."

"I have this same setup, I bought the flamethrower coil 1.5 ohm 40k volt. Should I take all three purple wires that run to the resistor and run them to + side of coil and remove the resistor???"

"El,

I've got 3 purple wires going into one end of the resistor and 2 that go out. I see I have to eliminate one of them and hook the rest to the plus side of the coil. How do I know which purple wire to eliminate?? Voltage test??

Thanx, Denny"
 
"Denny, if your arrangement is

"Denny, if your arrangement is identical to what we discussed at the beginning of the thread, you don't eliminate any of the three purple wires that go to one side of the resistor, because you will need all three: one comes from the they switch, one goes to the alternator, and another to the choke.

Now, from the ones that come out of the resistor, one goes to the ignition coil, and the other one goes to the starter solenoid. You no longer need either and you can remove both, as now the three purple wires at the other side of the resistor will be connected to the + of the coil. However, if you remove these two wires, remember that one of them goes to the starter solenoid and you should disconnect it from the solenoid side as well. It should be easy for you to spot that wire connected to the solenoid, as it should also be purple."

"Thanx El,

I'm on it. I'll be down it tommorrow.

Thanx for your help, I'll post you with the results. Hope this solves all my problems (and 1 of yours) ..

Thanx again

Denny"
