Breva 750 in stop and go traffic, like sit for a minute or two then move a car length or two, repeat. I figured the engine didn't like the lack of airflow so I would occasionally turn it off with the kill switch and hope it cooled in the cold weather (thirties). One of the times it wouldn't restart.
All lights are on except the EFI light, it doesn't come on and off when turning on the ignition. The starter button does nothing. It's like the ECU said, "Nope!" It was too dark to do any troubleshooting.

At a guess I would look at the start relay fuse, it may have popped.
It may also be the ignition switch.

I think the engine is also cooled by the oil circulating, when you switch off the engine in traffic the temperature will actually rise momentarily before it cools down.
So technically, your Guzzi didn't die, you killed it :grin: :boozing:
-
Kill switch?
-
Kill switch?
OH - you gotta hope its not that :wink:
I usually fall foul of the kill switch when I stop on a hill and want to park it in gear so stop the engine with the kill switch.
Panic always ensues when I subsequently push the start button and nothing happens
Might be worth cycling kill switch and ignition a couple of times just in case you're in luck and then check the fuses
-
Could you please elaborate a bit more.
How long were you in stop and go traffic? (Did the bike have a chance to get overheated?)
What was the outside temp?
Has the bike been restarted since? (As in completely cooled down.)
If yes, did it run ok after that?

edit: went back and re-read your post. (It was early.) Anyway, Yeah, I'm with the others. Battery.
-
From the East Coast I'll guess a dying battery...long time at below charging...repeated starts...no go on the button kickstart...small Breva with an older battery, below 12,4-6 volts at idle...
Pretty sure you'd want to keep it idling to circulate oil to cool, but IDONTKNOW....
-
Not enough voltage to run EFI.
-
It was the fuse.

Refresh my memory guys, is that the fuse that is 15 amps from the factory that some change to 20 amps due to them failing after a while as they age?
I do carry a small container of fuses in my riding jacket. As a result I have needed any in 12 years. :undecided: :grin:
-
Easy fix :thumb:
Congrats,
Tom

Yes, the fuse is subjected to up to 50 Amps for a split second, a 20 Amp has a greater margin.

When the bike is new and the ignition switch is in great shape the inrush pulse is very short (about 20 mS) and the 15 Amp fuse is fine but as the wiring builds up some resistance the pulse gets longer, double or more.
If you bypass the ignition switch the current goes up but the time comes down

Kiwi--what a great chart. Thanks.
To the original poster. I don't believe you need to baby the engine in stop and go traffic like that, especially in 30 degree weather. The engines are designed to shed sufficient heat in forseeable stop and go scenarios.

Yes to SmithSwede all round. Now in August in Northern Nevada there will be engine heat management issues, but not at 30F, unless the SB is much more sensitive than my big block Breva was and I don't recall any posts saying anything to that effect.
Glad it was a fuse and that there's an easy fix so it won't recur.

Nic, the 2TB's do run hot. Oil temp can get real high. I have only had mine begin to let me know that it was beginning to get a bit warm just once, mainly through the sound of the motor changing just a bit. Motor was still fairly new and I had been gridlocked for a fair time on a really warm day. That is the only time I have shut it off while in traffic. Fired up straight away and once I got moving with no furthers probs.

Please disregard my post in light of 1st hand knowledge! Thanks Muzz!

I'm not trying to argue with anyone. But I've got plenty of experience with a 2013 small block Stone running all across Texas, including summer-time stop and go traffic. I've not had any issues.
If the bike is in tune, and you are using the synthetic 10W-60, I think you have nothing to worry about.
Stop and go traffic is foreseeable.
-
Just had a look and I think the 2013 is a 1TB. The finning always looks to have more on that engine than the 2TB.
Yeah, I run the correct oil, all in tune. As I said, only happened the once. It was a Nor Wester, which where I live can hit 35degC at the drop of a hat. It just started tinkling as I would move forward. As the traffic was going like a lizard drinking I thought I would turn it off and any traffic movement I just propelled it by leg power. With a nearly new bike the last thing I wanted to do was seize it.
I have never bothered with a sump extender as, other than that one time, I have never had a problem in stop/go traffic or in fact, any running.
