Blackout during riding

[Cuda]

Drinking to Blackout.... need to join AA

I was having problems with a Deutz diesel powered machine , It did not turn over fast , diesels need to spin fast to start  everytime our temps got to 60 or below it got real s l o w  found  out it was a bad conection inside the conector  , had a auto electrical shop put a new end on the large wire ZIPPITY DO DAH.

Well, I am riding for last couple of days without any problems.
I checked the battery connections, ground connections, ECU connections and all is solid tight and no loose screws or connections.
I tried the kill switch during riding and , yes, the power was still on, only engine died.
I wonder if that blackout would leave any trace in the ECU for service guy to check in the computer as a fault ?
Since it was one time occurrence and all looks running OK, now, I guess that it would be of no use to take bike to service man, except if there could be a fault recorded somewhere in the ECU.

Sorry if the title of the topic was confusing, but running 70+ mph during night outside town while overtaking car and suddenly all goes black is a hell of the experience and potentially RIP situation.

Thanks everybody for your thoughts and advices. 

If you found nothing external to the battery, there is likely an intermittent internal fault with it. I'd get another battery in the bike, before any further riding.

It is a bad ground wire somewhere, keep looking.

Either that or replace the battery.

Rafdog,  What year/model are you driving?

I have a 2012 C14.  Mine blacked out completely. Clutch was still engaged. I disengaged clutch, let her coast for a bit. I saw the LCD display come back to life and I re-engaged the clutch and the engine fired back up.

Since the negative battery cable is solidly connected at both ends then the culprit is most assuredly within the battery.  Granted, it only happened once but you sure as hell don't want it to ever happen again.  The battery may last another five years and not do it again, but your ass is on the line and I wouldn't bet it on that particular battery.  Spend the money on a new battery and enjoy the peace of mind you'll be able to enjoy.
Refer to my previous post for an explanation of my reasoning behind this one.

When you say that you checked all the connections does that mean that you disconnected them and cleaned them really well then connected it back up or that you just looked at them?

While I have not seen this on my C14, I did have the exact same thing happen on a Kawi ZX6 some years ago. Turned out to be the battery was on it's last legs. Replaced battery and never had another problem with it.

I am going to have to support the main ground failure idea. Nothing else could cause black out and engine failure of such a temporary nature. I am also going to endorse the idea of the failure being internal to the battery where you cannot see any problem. Here is a situation that took place recently that lends credence to this conjecture:

A guy I ride with has one of the fancy new BMW RRs (astonishing motorcycle). It started cutting out intermittently:

1. He took it to the BMW dealer, dealer said it was fixed and charged him a bunch of money because they couldn't find a warrantable problem.
2. He rode it, the bike still cut out.
3. Took it back to the BMW dealer, dealer said it was fixed and charged him some more money.
4. A friend rode it and it still cut out.
5. Took it back the the BMW dealer. Dealer said they couldn't figure out what was wrong and bumped the problem up to the BMW engineers.
6. My friend went back to check on the bike about a week later. It was in the weeds and nothing had been done.
7. My friend went home and brought back his trailer to take it home (but not before they charged him some more money).
8. The problem behaved just like a clogged fuel filter or collapsed breather tube so my friend began carefully disassembling the bike and searching for problems with the fuel system.
9. In the processed he noticed the the ground lug on the battery was loose (loose within the case, not just a loose cable connection).
10. He went back the the BMW dealer to get a new battery. They didn't have one but would order one and it would cost my freind a bunch of money.
11. He bought one from an aftermarket dealer, installed it and everything has worked fine since (except for his wallet, which is about a couple of grand lighter).

He was being sarcastic!

They are indeed the best- at overpricing and taking all your money for service!  I can't believe the audacity of that dealer.  He should have certainly demanded all his money back.

[gPink]

That would not have been proper BMW etiquette. I think one must act like money is no object.

OK, then, seriously, go mount your dern Canyon Cages...

Whoa there boys, lets not pick on BMW. Sure they have their quirks but they make some nice machines to go with those quirks.

Let's keep our criticism on Hardleys where it belongs....

So where do we have to sign up for the mandatory sensitivity training?

Kirby likes you like you am too- he told me so.

Not sure if that statement should be comforting, cause queasiness or make you schedule an appointment right now....
