I am hoping that some of you electrical gurus can offer some suggestion. Here is the issue:

- 07 DL650
- purchased used a month ago with 10,000 miles on it
- has worked like a charm for a month
- suddenly will not start. Rode it yesterday. Stopped to run into a store and do an errand; came back out 10 mins later. Dead.
- dash would not light up at first but does so intermittently , but as soon as the starter button is depressed, everything shuts down. No rhyme or reason to getting the dash to light up again. It just seems to rest a bit and then lights up when you turn on the key again.
- When the dash does light up, if you don't press the starter, everything (eg. fuel pump, signals, horn, etc) works. It just goes "black" if you hit the starter.
- all fuses are fine
- cycling kill switch has no effect
- battery load tested and is fine
- bypassed the clutch switch - no starter action when the button is pressed but at least it does not cause everything else to shut down.
- side stand up, in neutral, clutch switch bypassed - everything works except nothing from the starter.
- It has heated grips and an outlet for heated gear as well as 4 accessory, marine grade outlets. Isolating all the auxillary wiring (ie. disconnecting the accessory fuse box) does not change anythin
- clock works but goes blank if the starter button is pressed. It does come back on if you cycle the ignition key.

Right now it is at the shop but it has them baffled although they have not looked at it extensively yet. I have asked them to try a new battery even though the one in it tested OK on the bench. I understand that the battery may be fubared even though it tests fine. At least it should rule out a significant problem.

Hoping someone here can offer some sage advice.

As luck would have it, my daughter was going to leave tomorrow with it on a 2000 mile trip. Looks like she may have to suffer a bit on her sport bike.

Thanks

+1 on checking connections.
It's not unheard of to have a corroaded connection that works with a small load then opens up with a big draw like starting the bike.

Check the crimp terminals as well. DAMHIKT

I've had batteries fail on both my DL650 and DL1000. In both cases, they failed with the exact same symptoms you're describing.

If it's not a battery cable connection issue, it's the battery. Probably the battery.

Get a new battery and Go Ride!

Thats also a possibility. The internal buss bar connecting the cells might crack for example and give you the same response.
Runs the dash but opens up under starting load. And might temporarily heal itself for a short while.

Sure sounds like a bad battery to me, but I'm sure that's the first thing the shop checked, hoping to sell you a new one. As mentioned, I vote next for a bad ground, at either end of the battery lead. While you're in there, remove and clean both battery cables (remove the negative first!). After that it's chasing ground connections all over the bike. Not fun or fast. BTW, what does a voltmeter say if you hook it up across the battery and try to start the engine? Might be a clue.

Good luck!

Well I had to leave town but my daughter went and picked up the bike. New battery and they found a loose connection somewhere. It appears to be working fine now so I won;t know if it was a battery or the connection until I get home next week. Good news is that it is running fine now so she is good to go to take off this weekend for a 2k trip. She is going to ride it around town tomorrow as well to make sure before she heads out.
Thanks to all who offered advice. I really appreciate it.

update - it was a bad battery. Subsequent load tests failed 3 out of 5 times. ie. sometimes it tested fine, other times it failed. So......load testing is not 100% definitive of battery health.
