No spark
Just bought my first Harley this summer - a 14 year old Hertitage Softail Classic. What a cool bike! As I was a rice grinder dude in my younger days. Anyhow in late September I was out riding and it was just like someone turned the key off - no spark. So I changed (as instructed) first the coil, then ignition control box, and finally the crank position sensor. Still no spark. So now I have a Clymer service manual. Took the rear tire off and inner fender, hoping I might just find some broken wires or something, but no deal. Anyone who could steer me where to go next - I would be grateful. The manual isn't clear on what to do after replacing all those parts.
Please help.
Thanks, Lydell

Did the Clymer manual "instruct" changing out those parts? - doesn't sound like a sound diagnostic approach.
Attached is the page from my HD manual to give you some idea of the ignition coil power layout, which may be similar to yours, but best you look at getting this diagram specific to your model.
This diagram will help when testing for power on the coils etc. using a test lamp or multimeter.

Welcome to the Forum from Colorado!
Did you check for corrosion and loose connections in the ignition switch? Or the kill switch? Are all the grounds solid without corrosion?

Thank you for your reply. I will dive into it again over the weekend and will certainly look at all that. I love the style of the bike but at 14 years old I suppose these kinds of issues will come up. Thanks again.

Hello Professor. The middle pole of the connector wire at the coil has about 11 volts. The outside poles of the connector wire have no power, even when cranking the motor. They should have power when cranking shouldn't they? Fuses are good, not sure if a relay can be tested. There is only one relay. Wires look to be tight and the best I can see wiring seems to be Ok with nothing loose, bare, or broken. Any thoughts? Thanks.

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.
