msd ignition- good deal?

....

However, the breakthrough voltage as you call it depends on the resistance between the hot side and gnd. If you increase the resistance, IE gap the plugs wider or run a denser mixture, you are going to increase the voltage the coil ramps up to.

In a situation where you have a plug that's really badly fouled or otherwise, you would get very high resistance and as a result very high breakthrough voltage....

Precisely. This is readily observeable with a suitable O-scope. Those fancy 40,000 volt coils rarely if ever actually develop that much voltage.

That Orange wire hurts BAD!

don't touch that Orange wire while it is running, either

why not? Im still alive... lol felt kinda funny I must admit

Well I hooked it up and the $25 MSD didn't work. The junkyard has a 30 day exchange so I figured I have 30 days to fix it. A few nights with my tester and a trip to radio shack and I got it going. Wow, what a zap! I haven't even hooked up the TFI coil or heavier plug wires yet.
It helped with my idle problems quite a bit- definitely noticable. The best thing it did is make me look even closer at my carb when it still idled bad. I'm leaking fuel/sucking air at the carb base something awful.

So I guess to answer my own question from the top of this forum... Yes, $25 is worth it for a MSD module. :shockin:

Congrats! Got a picture of this module? Was it a stock dodge part?

Not a stock part, it's a MSD 6200. Looks like every other MSD box in the world.
