dead or alive? sudden death!

[chihuasbigdog]

so here it is again..... after a long month without riding (switching jobs) and wanted to ride as much as I can before the real cold hits town, I take out the k9, push the start button, and the motor started!!!!
havent done anything to it, not even checked the cables but my mind started playing me about ITS OK! ITS OK! ITS OK! GO RIDE AND THE DOG BE JUST FINE!!!

so, I take her for a 1 hour ride, NO ISSUES AT ALL!!! but when i was getting it inside the garage, THE BIATCH STOP RUNNING!!!!

no starter clicking, so I remember that Deadone ask for what lights go on when this shit happens.... here is the answer.
[ame=http://www.youtube.com/watch?v=LNaqlihZj6w]YouTube - k9 shits again[/ame]

NO LIGHTS! it just went down......
i record it on darkness cause in the day the leds werent noticeable. the led that is on is the upper 3rd from left to right no starting engine,then it changes to the 4th and the bike starts.
when it dies all the leds go off, not the lights, nor the turning lights, nothing at all, just the leds. and when hitting the start button , the 3rd led goes on..... and have to wait until the 4th is on and start the bike.
yellow and blu lil lights are from the ignition.... yellow in the right is the ignition led of my EHC.

any help????

Which EHC do you have? Red lits are fault lits. 3rd and 4th lights are air compressor and air relief. Do you have air ride on it?

Still seems you have a loose connection somewhere so I would pull the harness' and ensure the EHC is full of die-eclectric grease and reconnect them ensuring a good connection. Same with the battery cables.

you laughing at me???? no air ride !!!!!
no sissy bar either !!!!

Ha ha, but thats what the red lits are for. Check those connections and ensure they aren't grounded somewhere. Most of the wires have the names of what they supply on them.

I can not tell from your video. What color is the potting material (what the metal case is filled with) of the EHC. Is it black or clear? Is it hard potting or soft?

how you ve been doing???
apparently was filled with clear grease like soft silicone.... i remove all that s*it, and put dielectric grease.... and nothing.
it breathes and dead, breathes and dead.....

I think these guys are on track but here are two more things to check. I have a 05 chopper and the ignition switch caused the same symptoms. It would be fine for awhile then just die like you turned if off. I would cycle the key switch and it would fire right back up.
My buddies 06k9 was doing the same thing and it turned out to be the ignition module. His was easier to diagnosis because his had these symptoms but finally wouldn't start at all.
Anyway two more things to check from real life experiences.

buddy, thanks, ive tried all!!! when I cycle the key again and again, nothing happens, same led on and no engine.

how about crank sensor?just something to look at.

No he's talking about the top of the ehc. All the potting. The stuff around the led's and covering the circuit board. What color is it and is it soft or hard.

Okay, I was having the same thing happen on my 07 Bulldog.

Check all the CRIMPED connectors that attach wires to the battery terminals, especially the smaller 18ga. wires. The ring-tounge wire crimps on my 07 had the wires loose and ready to fall out causing too little current to run the EHC and kill it. Recrimp the connectors, soldering could cause the wire to break off from vibration. Soldered joints are not allowed on aircaraft systems due to vibration, so it may be a good rule to follow.

Mine seems to be running so far but not enough miles to tell yet. It could be your ignition key switch also.

Good Luck!

ooooh, it is soft and clear-transparent!!! thanks gas man.

Say it isn't so... You still have a few things to check before we jump to conclusions. You know how sensitive these things can be. Hell I've had several electrical issues like most. YOu will get it worked out. Shitty fatty..

hey shitty fatty kiddo!!!
I love this f**n damn thing!!! and I know ill work it out. just trying to get some directions of members. how you doing???

The EHC you have was built two ways. One was with hard potting material and the other with soft. The hard was part of the EHC recall, the soft was not but I think some of them could have had the same issue. What you discribed to me sounds like a solder joint issue on the ignition FET on the bottom of the board. As it heats up it expands and the connection (on the circuit board) becomes loose. Once it cools down you can start it again, vibration could play a role as well. Sorry to tell you but if this is the case you are looking at a new EHC. Make sure to double and triple check the ignition key and ignition module before you go thru the expense of an EHC. I could build up a little pigtail that would allow you to hard wire your ignition module (thru a deferent switch), if you continue to have the issue it is the ignition module, if not you can bet it is the EHC. The fact that you can cycle the igntion switch an it does not help tells me you could probably rule out the ignition switch. Wiggle the hell out of it to be sure and see what happenes. You could bypass that one as well to rule it out.

thanks Mike, helpin as usual.... Gas Man is sending me a stock ignition module... so ill let you know.

 

[Gas Man]

Sending? Sent bud!

hahaha !!! thanks!!!

Guess the first thing to go when you leave BDM is your memory. Dead brought to my attention it was the soft potted EHC that was recalled not the Hard. I had seen issues with the hard as you described but I guess it wasn't recalled. Either way before you shell out money for an EHC if it comes to it, you better check with BDM to make sure yours is not on the recall list.

Keep us posted.

This is interesting. Picked up a used '06 K9 today in
Dallas/Fort Worth area. Strokers Dallas just replaced
the battery. Drove it probably 50 miles on and off
throughout the day and good.....then tonight, driving along
maybe 40 mph and horn starts honking and turn signals
start flashing and ump....motor dies; pull off to side
of road.....when turning key to on....after approx 5 seconds...horn starts honking again......gave it probably
10 minutes and fires up. I just had left my house about
a mile before this happened....motor probably not hot
yet....it was 44 degrees outside. After about another
6-7 miles....same deal.....horn starts honking and
turn signals flashing and motor dies. Wait 10 minutes.....
fires back-up. As thread subject says.....HELP!
