2004 Starts and then dies!

[Trashman]

I have been chasing a problem on my 04 chopper since last Sunday. Sometimes I get the red power light, after hitting the run button, on EHC and sometimes not. When the red power light does come on the bike will crank and start right up. Bike will run 15-20 seconds and die! Bike will just crank, not start, if red power light does not come on after hitting the run button. I just replaced the cam sensor this evening as well as the 30A circuit breaker. I am at a loss with chasing this problem. Symptom sound familiar to anyone? I have checked coil, plug spark, fuel etc. Need some help with this problem!

 

[mobsta]

you still have the old ehc right?

 

[mobsta]

when the bike dosent start but cranks do you have spark at the plugs

 

[Trashman]

I have good spark at the plugs when it fires up or when it doesn't. I have a used EHC coming from one of our members after he installed wire plus, smart man! I have lubed the EHC as well as any connectors I have been looking at with dialectric grease. I'm wondering about the EHC though!

 

[mobsta]

if you have spark when it runs and spark when it dosent sounds like fuel,in therory if you have spark,fuel and compression should run correct?

 

[mobsta]

those old ehc's were junk

 

[mobsta]

have you pulled your hand control and checked board or connection at the board

 

[Trashman]

Mobsta, can't get any simpler than that. Air I got, fuel I'm getting, pulled the breather the other night and twist the throttle and she's spraying fine, spark looks strong. The thing that baffles me is it will fire right off and then just dies!

 

[mobsta]

what about the hand control?

 

[mobsta]

one other thing try wiggling your key and see if the light comes on

 

[Trashman]

Ya know, I've been thing that but I hate getting into that throttle. I installed the cruze mate a little over a year ago and putting that assy back together was a bitch. I may have to take a deep breath this weekend and dive back into the throttle to look at the pcb connection. Sure wish I new a talented young lady with three small hands that i could call on to put the damn thing back together...

 

[Trashman]

Have not tried the key wiggle. When I had coild cover off the other night I check all wires and connections. I'll try the key wiggle tomorrow.

 

[mobsta]

these ign switches have problems,ya know someone on here had a cruisemate done and the tech didnt get the shavings out of the control and it was shortn out the board,just a thought

 

[mobsta]

those controls are not that hard to deal with,just take your time and watch everything like the cable furrels they like to walk away

 

[Trashman]

Yea I made damn sure everthing was clean after I did the cruze mate and before I buttoned it up. Washed everthing down with electro contact cleaner. I hope I'm missing something simple here. I'll keep plugging away at it until I fix it. It's not going to the shop! Mobsta, I appreciate you hanging with me on the problem. Calling it a day!

 

[mobsta]

no problem bro,sometimes its best to let it go for awhile and get back to it with a clear head,have a good evening,i check in tomorrow,if i come up with anything i will let you know,again those old ehcs were trouble.

 

[Eric]

when you installed the cruise mate.. make sure no chips of metal made its way into the handcontrol board,, it maybe shorting out & shutting it off..

 

[mobsta]

we covered that eric but he says he got it all but you never know

 

[surferdude]

Is your enrichner up or down? Just asking ... hopefully it's something simple. :up:
