Long trip planned for Tuesday! Bike won't start. 2012 Vstrom 650

Hi

2012 V-strom 650

Added Denali d4 lights, real proud of myself, hard wired to the battery because there is a switch and I was having trouble finding a hot wire that would only allow them to be turned on when the bike was on, so I attached then to the battery and figured I wouldn't accidentally leave on lights that are brighter than the sun.

From my volt meter I could see I was at 11.4 volts, then a week or so later it's dead. Normally it could handle a week of the battery tender.

I hooked it up to the battery tender now and it's at 11.1 but when I try and fire it up it just clicks, and nothing.

Tried jumping it as well after that didn't work.

Ideas? Other than be smarter???

Tough to discover at 6pm on a Friday, planned to ride from St Louis to Boulder CO starting on Tuesday morning....

Any help would be appreciated.

How old is your battery ?? That seems awfully low voltage.

Get a new battery and disconnect your new lights until you get a better wiring figured out. Always go back to the last thing you did when troubleshooting. Put it back to where it worked and then move ahead.

Thanks, I'd guess it's the original battery, new bike to me, never had terrible starting it up before the lights, the volt meter is also always on whether the bike is on our not which seems dumb but was working okay also.
I'll try letting it recharge fully with the battery tender.

What is an acceptable voltage level?

Not a cop is right on here. Wanna enjoy your trip?

1. Remove the lights, figure them out when you get back.
2. Replace the battery and keep an eye on the voltmeter while gone. It needs t stay up in the range you were used to seeing it prior to this issue.

Unhooked lights and volt meter and gave it about 5-10 attempts and got it started, hooked everything back up and got it to start again. The volt meter says it's making 13.6 - ish when the bike is on, that good?

Perhaps the battery just went very dead? Have ridden in a couple weeks. I have it back in the battery tender, it's at 11.7 volts now sitting.

When I removed the positive battery terminal while it was running to test connections it would sputter and the display would go a bit crazy, I would rev it to keep it running. shouldn't it be fine once it's running without the battery connected?

Get a new battery anyway??

Throw an actual charger on that battery, the tender is meant to maintain a battery, not charge it. I wouldn't trust the tender to charge a battery that's only 11.7

Messing with the lights install, draining the battery, then expecting the tender to recharge it, seems like the problem to me, but a new battery would certainly give you absolute peace of mind for your impending trip. But don't toss the old one, I'd bet it's okay.

Thanks, all good advice from everyone, thank you. I was looking at the Yuasa YTX12-BS AGM Battery

Any advice there?

My bikes resting voltage is about 12.6. Charging is best about 14.5 or so on your volt meter when running 4K rpm or higher.
