Sudden battery death!

Energy One

My battery went from happy to dead in a flash yesterday. Went out for a ride, all was well. Had just adjusted my clutch and the slipping was gone, I was all grins! Got home and ran inside to take care of some things. Went back out 10 minutes later, hit the start button, get about half an engine crank, then dead! My lights come back real dim and my WP unit is buzzing like a bee. Disconnected everything and started troubleshooting the WP thinking that had to be part of the problem. First step, as always - check voltage. 10.1v !?!?! WTF!?! Take the battery out and test a small 12v lamp and it won’t even light that. Won’t take a charge either. Toasted cell I'm assuming, voltage is about right. It was a Drag Specialties that came with the bike. It's been struggling real bad since my CR's have been toast for a while.

Started working on things and next thing I know half the bike's on the floor, the WP is cut out completely. Today saw the switch over to S & S Rocker Boxes as well as the new CR's. Even made a DIY CR tool which I'll post details about soon. During the week I'm hoping to get the M-unit wired up and get a feel for it. Oh yeah, went out and bought a Harley AGM battery today, on Sunday no less. Going to give that a run for a while as it’s an awfully convenient solution.

:cheers:

Thanks spades, I'll definitely check that. Pretty sure this was an over-amperage situation on an older battery. Good call though, I should verify the regulator (new a few months ago) is funtioning properly so my next battery doesn't croak.

I'm talking from Drag Specialties experience here, those batteries suck!!!!!!!!!! I got a new one, 310 CCA, lasted about 2 months. But WTF, I get a new one for free since my warranty is still in affect. It lasted about a month at best. Everything was working fine. The VR, stator, CR, everything! Finally, even though I could have received another battery for free, I went with a Braille. Rocky, my wife, has a HD battery in her Mastiff and it's been trouble free for 3 years. I wouldn't check too much other than just the VR output once you start your dog with that new HD battery.

I put in a battery from Oreillys that has been fine on my bike for 2 years now. Purple something. Just an option as well. Again though check that VR with the bike running just to verify.
