coils and ohms

[freddyray21]

I just received my new Ignitor igntion Friday. Too late to put it on before taking the boat to the lake, but I did receive it. I have a question though. The coil I purchased with it (60,000 volt high performance) has a 1.8 ohm ballast resistor attached to it. The Ignitor directions say a 4 cyl. should have a minimum of 3.0 ohms resistance. My current set up which ran fine for me all weekend has a 1.6 ohm ballast resistor. I am changing to the Ignitor for hopes of a little better hole shot, but mostly so I won't have to keep changing points all the time. The current set up is not original as I had to bypass a pass resistor wire and I put the ballast resistor in to match the coil it had it in. Since my new coil has a ballast resistor that matches it shouldn't that be fine? What is the effect on the different resistance for different cyl. motors? The 6 & 8 cyl. have the 1.6 - 1.8 and the 4cyl are supposed to have 3.0? Or is that just when using the Ignitor? I noticed the same company that sells the Ignitor sells a coil with a 3.0 ohm resistance they say is perfect for four cylinders? Fred

Re: coils and ohms

If you expect a better hole shot just by replacing the points, then you are going to be very dissappointed.
Follow the instructions and it will work. Try to second guess it and it won't.
