Testing The Charging System
Take a look here in the self help section on how to test the regulator.

My 2006 Ultra will not fire on #2 cylinder

It is not a charging problem.. I have been an electrical tech for 30 years.. It does not have spark at the rear plug..

Do you have an owners manual? Does your bike have parade mode? Is it possible that is causing the problem?

I was thinking that maybe it had something to do with my problem.. I don't think it can be disabled on the 06 model...The way I understand it is it stops it from firing the rear cylinder and still puts fuel in it to help cool it when it gets too hot... I did disconnect the temp sensor with no change.. It will run after it has been sitting for a while then starts not firing the rear plug after a few seconds.. It will fire hit and miss every now and again... I put my timing light on it and watch it fire like I said every once and a while.. Front cylinder never misfires.. New coil, 2 sets of new plugs, wires .Crank sensor...
I am seriously thinking about getting a used ECM off E-Bay and trying that... (Edit) I can get one for $120.00 low miles..

That makes sense to me, seems to me the ECM needs to see compression to fire the plug on these TC engines I assume you have good numbers front and rear? I dunno if a bad wire on an injector could interrupt a spark it may be worth thinking on Good Luck and keep us posted, this 1 has me stumped
What I suggested you read was how to test the voltage regulator which is what dolt suggested, it's covered in the posting. If you have a bad regulator you'll get erratic or no spark.

Might try the MAP sensor before buying an ECM but the ECM swap is a good idea. PN is 32416-10; the early PN was superseded in MY2009. I was going to suggest the head temp sensor but I believe I read that you had tried with it disconnected with no change.
