Hello 1004ron. Opened up much of the wiring to check for broken, bare or corroded wiring. All looked to be OK. Took the wire connector off the coil and the middle pole had about 11 volts, while the outer two poles had no power, not even while cranking. They should have power when the engine is cranking shouldn't they? Thanks.
Also, 11v is a sign that the battery is not fully charged - the voltage that you measured on the ignition coils connector comes from the System Relay, and should be very close to what you measure across the battery terminals.

12.26 at the battery. 11.28 on the middle connector - just took both readings. Checked the kill switch as some had suggested by poking into each wire while the switch was on. Couldn't read much voltage but there is continuity. As you might have guessed at this point, I'm not so experienced with electrical issues, or Harley's either. What's next?

ok....so.....kill switch is good to go..... the coil / CPS / ecm were changed out ? right ? ....you have power to the control module , coil ..... now...check your HT leads for continuity.....

Hello Harley Cruiser. My manual doesn't have the poles marked like that. But when I look at the wiring diagram I believe the wire you are referring to is a solid red, right next to a solid black, which are part of the two connectors that connect to the ignition modual. Hoping this agrees with what you suggested, I poked the red prong of my tester into that solid red, and the black prong to a ground on the frame. I did this with the ignition switch on. Nothing. Was I supposed to get a 12 volt reading? Thanks.

HT is "high tension" leads.....aka "spark plug wires" pull them off the coil ( while holding the lower boot) don't yank on the smaller wire portion . check for continuity on each HT lead.

at this point if all checks out with the plug leads......pull out the spark plugs (both)and connect one of them to the leads....turn the ignition to "on" bar switch to "run"......while holding the rubber boot section of the HT lead....place the end of the plug on one of the engine cooling fins ( for ground) hit the starter and check for spark .
