Going down the road today and my 06 Ultra just stops running. No spit sputter, nothing. trailered it home and now looking for the a bad wire, checking the conections...you know the easy stuff...no luck so far...got to be something easy...right?...

I'm thinking some sort of module/sensor which sends fuel information. The crank module was the culprit when it happened to me.

Peace

first check the ignition lights, working? next does it crank? next check LT side of coil, then check HT side of coil, then get a spare spark plug and take one lead off and connect it to spare plug, put plug base against any metal surface on bike frame/engine, does it spark when cranking?

Sounds like the main circuit breaker. Back a few years ago they were notorious for going out, especially when riding in heat. They finally had a recall on it. Many of my friends that rode Ultras carried one with them.

Haven't heard the problem in a while, but certainly worth a check.

That happened to me once. Turns out it was a blown fuse.

Thanks for the replys so far. I started with checking the wiring...all looks good. all the fuses are good. I'm giving up for the night (just to darn hot out there) tomorrow checking for spark. I've got a Cobra FI200 installed that I'm going to disconect and see what that brings. If this helps... all other functions are working i.e.; lights, fuel pump and gauges plus it's getting gas

Does it start back up after this happens?

Haven't got this solved yet...tring to figure out how to test the coil. I realy don't want to take it to the stealer. I've got it all torn up. Still no spark!

To help clarify this problem, The bike was running just fine, no problems at all and no signs of anything that would be a potential problem. I was on the throttle doing around 55 or 60 and all the sudden nothing! all the lights, gauges, etc. fine. But no running of the engine...it turns over fine, shows getting oil pressure, sometimes the engine light will go off then on, sometimes it will be off when I turn the switches on other times not.

may be a long shot-----check the battery--was told by supplier that they were having trouble with some being bad --not holding charge--I had a loose cable and my bike did basiclly the same thing--just die while under power.

Hang on, did you say you are having trouble checking the coil to see if its working??? 

Also, there is a wire goes from Ignition switch to LT side of coil, if the light is screwing around, sometimes on and sometimes off when cranking then it suggests a simple loose contact on that wire.....

There is power going to the coil but, (with the plug test) there's no spark. Also, puled out the Crank position sensor and checked it for metal, dirt...clean as it can be!...and as far as the battery, just put a new jell type one in this spring and installed a new Accel regulator

Boy do I feel like a moron...The bike is running!!! real eazy fix, First of all thanks to all for your help!!! Second, The 1st plug I used to do the spark test must of been bad, I used a different plug and I got spark! so I had the tank off so set it up on the backbone and pluged it in, when I put power to it I could hear a sound in the tank like there was gas being squirted out of a hose. I took it apart and low and behold the gas line had fell off of the pump. Stuck it back on hit the switch and she fired right up! I'm going to get a new clamp and install it tomorrow...all's good!!! This will be the First time that I didn't have to shell out a bunch of coin to fix a problem!

Well you got it running and that's what counts

The fuel line came loose from the pump!!! Now that's a new one. Glad ya found it.

peace
