Default No spark.

Ok, I'll try here.
no spark.
replaced CPS, coil, battery fully charged (new battery), and still no spark.
It's a 2001 Electra Glide, under total restoration.
Finished, with exceptions of stripe work, and ready to put on the road. That is, if I can get it started again. When I first started it, it ran great for about 2 weeks while I was finishing up the small items. Then, it had issues with idling, then would start at all. After a fight with that, I realized I had failed to put the ground wire from the engine to the frame....duh!! It started up, ran fine, then idle went to hell, it started to backfire, sounding like it was "loading up" and then died. Thought fuel was the issue, but the plugs are wet with fuel, but no spark to set it off. Put in new CPS, and coil, nothing. Checked all fuses, battery, anything I could think of ( I'm not a novice mechanic). Someone tried to tell me that it was a fuel issue, and I may not know as much as he does, but what the hell does the fuel system have to do with the spark? Unless there's some connection in Harley's that I'm not aware of.
Anyway, help!!!!

Bike has a CPS (Cam Position Sensor) and a CKP (Crank Position Sensor). If there is no tach signal when cranking, that's a quick way to know the CKP is out. Test the CKP AC voltage output when cranking. Check codes. A dead CKP on a MM typically won't set a code.

I replaced the CKS, I call it a CPS, sorry for the confusion, but not the cam sensor. That may be the issue, and now I know how to check it.

Sorry to hear that you still having the problem.
I agree with Ed Ramberger. You should check the voltage.
I found an article about harley davidson no spark troubleshooting.
You may check. Hope this might help you.
https://protroubleshooting.com/harle...oubleshooting/
And let us know if the problem solved.

I`m gonna go out on a limb here and say who ever wrote that troubleshooting article has no experience working on a Harley ignition system. I`m guessing it is just a computer generated BS article ...

There is no run position and start position for the coil. That may be true for a `60s era slant six Dodge, but not a Harley Davidson.

No limb there. That's from back in the day of points being used to fire a coil.
Ballast resistor if I recall right.

I have better things to worry over. Just working on getting this thing going again.
I checked for a cam sensor at every dealer in my area, and others across the country, and none of them have one for my bike. All on "backorder " and the ones that do have one say they are "held" for someone else. Tried a few local independents, and still nothing. So it could be the middle of the month, if not after the first of the year before I can even get one.

Hello Dan89, I am one of the owners of the site protroubleshooting.com. We just launched the site and it is still in the child phase. I get no traffic whatsoever, for now, that's why I was very excited to see that someone visited my site from the Harley Davidson forum itself.

I am very sorry that the article was not up to the mark. The thing is I do not possess expertise on such topics. I hired a writer to write the article, who was supposed to be an expert on harley davidson engines. He convinced me well that he is the one for accomplishing the article. I think he got me there. Again, extremely sorry for the mishap.

I would appreciate any suggestions on making the site better. Thank you.
