NEW MEMEBER Hello everybody! 2014 Triumph Rocket 3 Roadster. Cheers from Orlando. I start the presentation with a nice Quiz!

Except my lithium fully charges every time to 100% . Never an issue with the charging, charging system is stock. Much more cranking power than stock battery. Charging system doesn’t have to work so hard, in my opinion. And to op, i think its your starter relay! When theyre going bad, sometimes they work, sometimes they dont. Key on you can feel the starter relay click on finger if touching relay, bike should start, when key is turned off in 30 seconds you can feel it click, when they start going bad they will stay open or on and drain battery, parasitic drain enough to kill battery. Thank you and have a great day

Yeah, its not the battery, I swapped for a brand new acid battery and after a test road...did the same thing. the fuel pump is not priming (no neutral light on the dashboard). I swaped the battery in 1 min. maybe I need to wait to the ECU reset by itself? ordering a fuel pump. BTW, it's summer in Florida and I can see some leaking on the front of the engine. more bad news :)
 
Can you hear the fuel pump run when the key is turned on?

Sorry, I missed that you already covered it.
I don't hear the fuel pump priming, after some rides (less than 14 min) this always happens.UPDATE, I change the lithium battery for a brand new acid battery and the problem still showing. I reset the ECU disconnecting the terminal for 20 min but it's a pain in the ass wait wherever and whenever this happen. Yesterday I was waiting in the 12pm sunshine of Florida. I will order a fuel pump but I don't know which one. maybe I need to clean the fuel pump system. BTW, checking for the fuel pump I saw a leaking on the front of the engine, I don't know if its coolant or oil. Now I have 2 problems...Fun : )
 
Greetings from sunny North Texas. Couple things, one the bike's charging system is regulated for an AGM battery. That means the lithium won't ever be fully charged because the voltage is less than the charging voltage required to sate a lithium battery. Two. the ground has to be solid for the bike to start and run properly, take the ground strap off, clean the connection and then reinstall. A lot of gremlins go away after the ground is made clean and tight.

How are sun there? we share something in common.


So I changed the battery for a brand new Acid battery.. the problem its still there.

I charged both batteries 100% with a NOCO genius 5, they're new, full and healthy batteries. I swaped them beetwen 1 min, I didn't reset the ECU but I don't thinks so Is that.

I will check the group tomorrow and will buy a new fuel pump system, or maybe clean this one?

beside that I found that I have a leaking on the front of the engine, between the radiator. I don't know if that is the issue (overheating) or its an other new problem.

they suggest me that I can clean the fuel pump and flush all the gas..but I don't know now with the leaking.

Welcome! Have you look under the tank maybe something wrong in the wiring . Can it only be your battery that does not a good contact and/or your positive lead damage. Does it do it all the time?
I swapped the battery for an acid one, same issue. Now this problem is more often than before, beside this issue I notice and other one,I can see that I have a leak of coolant or oil between the radiator and the engine.

when the bike its cool I can turn it on 3-4 times before this happens. always this issue starts after I ride for 20 min or more.
