Alright guys need some help, I was out last night and my bike decided to cut out on me. First thought was I just grenaded my engine. Coasted to a stop..gave the bike a sec tried to crank it and nothing that sounded good or right when I hit the button. I ran diagnostic and got loss of compression cylinder 1, and then code for 2. Unfortunately I didn't write those down. I then was stuck waiting for a tow for 3 hours. Of course I forgot and it threw a lot of security codes from the tow home. This morning I went to run another diagnostic on it, and got
No rsp
B1154
Pn68924-07
Pn67261-08
Pn67459-04c
Pn32836-09a
I know the 1154 code is the clutch switch thing. And the rest are security codes. But it won't show me the loss of compression codes I got last night just the no resp. And I got brave and tried starting her and and roared to life like the day I got her. I want to clear the codes. But just curious as to what made her die like that and throw those codes... Too hot?? Vapor lock?? Can that happen? I want to take her around the block but just waiting on some feed back so i don't ruin her if there is a serious issue. Any advice would be greatly appreciated. Thanks in advance guys.

Hi from the UK and welcome to HDF. Could be as simple as a low battery, so start with the simple stuff first. Use a multimeter to check battery voltage, first with just the ignition turned on, engine not running. Start the engine and check voltage again. If that is low or high, follow the charging circuit checks in the Tech Electrical section stickies. Let us know what you find.
You have the codes recorded for future reference and they are mostly security codes, no motor malfunction codes. So clear the codes and run a compression test. If compression checks out, take her for a spin and see how she does; go from there.
I took it to Harley to run a diagnostic and of course he said it's probably my power commander which doesn't make sense to me. They said they clear the codes but they come back. But my bike is running and just died that once, I am going in tomorrow to ask them what codes are coming back. I think it's probably a fuse or battery issue like you guys are saying. They want me to replace my power commander, but before I even took it in he was said power commander before he even looked at it. Just sounds like they are trying to component replace without locating an issue. If it was a power commander failure wouldn't I be seeing serious problems like rough idle and or not starting? I have upgrade speakers and had been blasting the radio and everything during the hour and half ride, but still that doesn't explain the reoccurring code issue that there blaming on the power commander. I am really at a loss with computer issues but really seems like there passing the buck instead of starting from the ground up and the cheapest fixes first.

Joe, a Harley dealer cannot be an expert on every add-on feature on the market! Unless they are also a PC dealer with all that implies, they are not going to be able to diagnose something wrong with it. Having said that it does seem odd that they knew what was wrong before even looking at your bike!
I had a Power commander leave me stranded.I took the seat off,took it out of the 'loop',and my bike started,and ran fine.Then when I got home,I installed the PC,and the bike wouldnt start.
Have the dealer take out the PC,and go from there.
Not that Im a big fan of my dealer,but when a bike comes in with a no start,the first thing they look for is a PC.I was told that they dont even sell the PC.

I would have did this that night, but I have aftermarket cams, I am not sure my bike will run right if at all if I go back to a stock mapping. If it was a stock motor I would take it off for the time being till I get some money saved up to fix the issue or leave it off.
Take the PC out of the loop. The motor might run a bit rough but if the PC is causing the codes (PCs do go bad) then the codes will stop. Send the PC back to Dyno Jet for analysis. Do a little investigative work on your own without relying on the dealer. They will convince you to dump the PC and by the SEPST and a dyno tune!
