2006 sportster XL883
No spark. Turns over. Good compression. Fuel and Air is good.

Spark plugs are good. Spark wires are good. Battery is good.
Coil secondaries measuring within the normal range. Forgot exactly what ohm it was, but it was in the normal range.
Coil primaries measuring resistance at 0.9 ohm which is 28% higher than the .0.5 to 0.7 ohm range. Possible problem? I was told this could be a problem but likely isn't. If anyone knows anything about that, feel free to let me know.
I tried to test the plug coming to the coil and got no voltage. I am not sure if I am testing that correctly though. If anyone knows a good way to test the coil connector coming to the coil, I'd give it a shot.

I jumped the ground wire and front coil wire on the ICM.(saw that on sportsterpedia) no spark.
I am leaning bad coil.
Is there anything I should check or tests I should do before replacing the coil?

 

Check your Crankshaft Position Sensor.

 

Update: Redid the ECM bypass test. Both plugs sparked. Assuming coil is good.

 

How would I test the crankshaft position sensor?

 

Well. I ordered one anyway. Found a twin power brand one for 17 dollars compared to the usual 50 ish they retail for. Will update once it arrives.

 

Run a Diagnostic Error Code Scan.

 

Good advice . I haven't had one fail during my ownership but my 04 Roadster is on its second one .

 

Can you do that on an 06 ?

 

I believe the changes in the 2004 Sportsters did allow checking for codes on the Speedometer.
(2004-2006) The Ignition Control Module (ICM) became more capable and included a digital communications link (SDB) between itself, the Turn Signal Module and the Speedometer.
The newly added Crankshaft Position Sensor (CKP) replaced the camshaft pickup as a more advanced means of sensing the engine revolutions
The new Manifold Air Pressure sensor (MAP) replaced the VOES as a more advanced means of sensing engine loads.
The Ignition Control Module for these years is programmable by the dealer to match the specific model bike, either 883 or 1200.
