Rocket 3R trying to START ITSELF !!

[Grumpy Pete]

1st way is electrical inside the starter solenoid when the contact washer welds to both terminals it will crank the motor until the battery runs down or u disconnect the bat.
2nd way there is something wrong and it binds the starter solenoid causing it to stay engaged. in the old days u could grab a hammer and give it a whack .
not recommended on a new bike especially since that is not your trouble.
i will take a guess
the starter relay (if they have not changed the design ) was hanging down (not in its proper position) and it got water in it causing it to short across . this would cause it to turn over for a while till the water boiled away then it would get wet again.
this should be an interesting thread so i will call one of the best electrical guys on the forum @DEcosse
if he has the time i hope he will join in

Thanks for that. I really love this bike. I’m just very worried about getting it back and leaving it in my garage with my other toys

i think sometimes u have to tell the dealer he is on the wrong path
you have an electric problem and if they don't fix it and it happens while it is raining and u are riding then u can either turn it off or it will take out the starter in a couple of miles.
edit
when the motor is running it is going to spin that starter about 5000 rpms and it is designed to spin about 150 rpm

That's crazy @Grumpy Pete sorry to hear of your woes. I'd be feeling quite miffed with those issues and lack of dealer knowledge and support. I often stop my bike by kicking down the sidestand with it still in gear. Kills the engine and then it's still in gear so doesn't roll away and fall over. If you had your bike in gear, would it still happen and the bike fall over?

No, it’s from Norfolk. Where Bob’s not necessarily Just your Uncle

At least its flat in Norfolk for when you have to push it home

Hi Martin,
Yes, if the bike was in gear, it would have moved forward and fallen over. As it had bypassed any switching. The kill switch was in the OFF position and the clutch lever wasn’t pulled in. So hear position and side stand switch would also have been bypassed. Something energised and activated the starter solenoid.
Ive had a reply from Triumph GB, and I’ve responded to that, but I’ve not heard back.
This is my area of expertise, ( City & Guilds fully qualified, Appretiship Trained ) I’ve worked on everything electrical, electronic and mechanical from robots, ships, cranes, factory processing and PLC controlled machinery including auto electrics. I’m thinking they’re gonna tell me that my giggle pin needs lubricating next.

 

[Martin-Brighton-uk]

I hope a software update resolves it. Again a physical key switch would mean this probably wouldn't happen along with other issues. Hope you don't get 'fobbed' off by the dealer.

It's still a beaut bike so I hope these problems are resolved quickly so you can get back to enjoying the bike.

Sounds like subsequent generations of the Lucas family have found gainful employment within the walls of the Triumph factories globally ....

Yeah, that about sums it up. They’ve now had the bike longer than I have had it. Sonde like they’re gonna fit a new starter solenoid and that will fix it….?? “That’s all fixed mate, working now” until the next time it rains…!!
Maybe they’d listen if I posted all the scary videos I have of this happening on YouTube. That’s the nuclear option, I’m sure that would lose them loads of potential customers.

Herman, that was going to be my guess as well
