Just added this setup to the 440 (68 Charger).
When I first hooked it up, I just used the wire coming from the ballast resistor.....ran like crap. So then i used a jumper wire straight from the battery to the coil, to see if the problem was from the low voltage coming off the ballast resistor......ran purrrfect.
So my question is, is it OK to bypass (remove) the ballast resistor using a jumper wire to connect the two wires that go to the ballast resistor, and run it like that with the new MSD system???
 
Mine is a 6AL but that's exactly what I did.

Run a jumper wire between the leads that go to the ballast and completely bypass it.
 
I've done it on a couple of cars now.

No problems with the Cuda and put about 10,000 miles on it that way.

Currently did it with my '63 330 and no problems at all.

Starts INSTANTLY and runs great!
