Help, no start

[chilipeppernorm]

Hey All,
Normally I wouldn't post such a question but am at a total loss. Went out to start the bike to gas it up for a trip tomorrow (150 miles) to the dealer for first service. Went through the following sequence.
1) ignition switch below tank ON
2) key fob on and light green
3) bike in neutral, clutch pulled in
4) top start rocker switch on to light up instrument cluster, get welcome rider sequence
5) hold starter switch on and dash cycles up showing Neutral, warning lights and gauges up, whirring sound for fuel pump, etc
6) Everything green and go, but no attempt to start, nothing.

Regroup,
Repeat above sequence from the beginning, turning everything on and off in proper order
Put bike in gear and back to Neutral in case of faulty switch
Put kickstand up in case of faulty switch and try again
Pull seat and check battery with voltmeter, 12.91 with clean terminals, all fuses intact.

I'm truly at a loss, can anyone see where I've missed something?? Any suggestions?? Light a candle, kill a chicken, do a voodoo dance?? Thanks in advance. Norm

It might be worth a try to reset the whole system. Have you tried pulling the power lead from positive terminal, letting it sit for 5 or 10 minutes, and then reconnecting the battery?

Sometimes a hard reset is the trick with an ECU. Just a suggestion. Should not impact your FOB but your SERVICE CHECK indicator will come on. Just need to reset the date and clock and it should go away.

Does the 2020 user's manual have a "No start" troubleshooting guide?

On the older Rockets, what you describe is an electrical issue often times a week battery or corroded cables. Or the first bikes, the overheated ignition. The 2020 should have none of these issues.

Can you push start it?

Start simple. Resting voltage is good, but what does the voltage do when you press the start button?
Even the later gen 1 Rockets starter circuit goes thru the Ecu. If it sees low voltage, you get nothing, just like you are experiencing now.


Also, never hurts to make sure the terminals are good and snug.

perhaps battery contacts need a clean. Mine were oxidised last week for some reason. Bike always kept indoors. So I ended up scraping all the gunk from.the terminals. With that low milage I can see an issue. Also try without bike stand

Update: Thanks one and all for your helpful and kind responses, I explored everyones advice and that helped to eliminate and narrow down the possibilities. I got ahold of the lead Tech at my dealer and he walked me through some further checks. Here's what happened in case anyone repeats my mistake.

Before attempting to start my bike I took a damp washcloth to clean the bug guts off the front of the bike from the last ride, this included wiping the front of the brake and clutch reservoirs. Under the clutch lever housing is a sensor switch, small flat and rectangular that press fits 2 tiny pins into the bottom of the housing and has a small metal tang that rests on the clutch lever pivot point. Pull the clutch lever in, metal tang rotates outward and the switch tells ECU the clutch is in, go ahead and allow the bike to start. My cloth caught the tang and pulled the switch down and away so no signal could be sent and bike won't start. Simply pressing the fitting back into place solved the problem.

Several thoughts here, first, this was a self inflicted gunshot wound so to speak in that I caused the problem. I did not know that switch existed and it didn't occur to me to look under the clutch lever. Second, in my opinion Triumph did not do themselves proud by attaching the switch in such a flimsy and insecure way. The pins that hold it are very tiny and appear rubber coated, and the tang is like a metal pocket clip on a cheap writing pen. Not what one would expect on a $22K motorcycle.
So if you're washing your bike with cloth or sponge and get around the clutch reservoir housing beware. I will try and attach a couple of photos but bear in mind I was holding the cell phone with one hand and the small flashlight with the other. I pulled the switch down for clarity sake, it was barely noticeable during troubleshooting. Hopefully I was the crash test dummy on the issue and nobody else with repeat my error. Thanks again to all.

You are right, that looks like a flimsy and insecure way to mount an important switch. Really glad you were able to track it down.

Glad it all worked out. Without the tech you would never think of this unless you were fiddling with clutch leaver before.

Thank you for the heads up.

Thanks a lot for your sharing. Bit disappointing from Triumph, don't you think so ? Especially if the problem has occurred also on the older models as it looks so -if my understanding is correct- : Clutch Switch Cleanup
Hey Triumph, have you heard about lessons learned ?
