MSD coil & resistor wire

[Alabama65stang]

Bought a MSD Blaster coil yesterday to go on my 200 I6. I have been running a Duraspark II out of a 78 Fairmont with the stock coil(out of the Fairmont) and Duraspark control box. The MSD coil instructions say to hook it up to the resistor wire for stock applications. Does this mean stock points type only or am I ok with the coil hooked up to a full 12V source? I have been running the old coil on the full 12V wire but the resistor wire is still available if I need it. I have it hooked up on the 12V wire now but don't want to burn anything up.

I am thinking about going to the MSD system in the future when the bank account allows it. What are the advantages of the MSD control box over the Duraspark?

You will want to wire the resistor anywhere b/tw the "+" positive wire to the coil. Best to mount resistor on fire-wall away from a heat source. Continuous 12 V to the coil will fry it running it for long periods of time. Just had to do this to coil in a j##p (with points in dist.) with an inline 6, kept burning up coils. The funny thing is I got tired of trying to fine tune it and ripped out the DSII and the control box in this one and put in a points dist. and it has never run better. Funny, huh?

Yes, the resistor wire hook up is for running stock points type systems. I'd run a full 12Vs to it to get max spark energy.

The MSD box versus the stock duraspark control box is a big difference. The MSD gives you mutliple sparks, where the DS2 box gives you one spark. the multispark results in high mileage and power since it gives a more complete burn.
