Anyone know what kind of voltage we are supposed to see at the spark module?

[Maltman]

I'm working on the same problem in my other thread, just wanted to break things apart.

I have a hunch that spark isn't there at high rpm since no knock is recorded and fuel is still there. So, I thought I'd check to see if I could eliminate the entire ignition system by verifying a voltage drop before the module......what I can do with this knowledge (if true), I don't know...but I have to do something!

Thanks,
