Not getting spark. Changed coil - still no spark.

Contact HD directly to request the diagram.

Did you check the Ignition, Points and Condenser. Also check compression there may be a stuck valve.

Coil or ECU or Crank sensor.

have you tested the coils?

Yes there is a fuse blow or a circuit breaker block on the bike. It's either under the seat or behind the triangular plate on the left side of the bike. Usually, the ignition circuit in on a different circuit from the lights.

Take a test light or a Volt Ohm meter and check for voltage on the coil. To test the coil, unplug a spark plug wire and insert another spark plug in it. Make sure the plug is grounded to the engine. Turn the ignition switch on and then back off. The spark plug should spark once when you turn the switch off. If not, you either don't have power to the coil, or the coil is bad.

To further test the coil, disconnect all wires from the coil and connect a DVOM (digital volt ohm meter) across the coil. Connect one lead from the meter to one of the small primary terminals and the other meter lead to the other primary terminal. Put the meter's function switch in OHMS, R x 1 scale. You should read 2 to 3 ohms, no more or less.

Good Luck
