Dyna S - no power to one coil

[msb]

Hi All,

This is a very basic question, but I don't understand the system well enough.

I've done the coil/relay/mod.

I'm seeing inconsistent voltage across the terminals on one coil - either close to 12 v or nothing. The + connection is fine, but the ground connection is really bad.

Question - can I connect the negative side of the coil directly to the battery?

Sorry - I don't understand how the Dyna S triggers the spark!

Thanks much in advance for any information.

the coil plus sides will be always be close to battery voltage
The negative sides switchs between battery and about 1 volt. The coils fire when the minus side goes from about 1 volt up to battery

Thanks for your response, posplayr. I see now that I need to connect the Black wire on the 2-3 coil to the black wire on the Dyna S.
