Unhappy 2008 Electrical system failure

Hi guys! I just signed up a minute ago and this will be my first thread.

So to set things up, I've been riding actively for about a month now, with no problems except for intermittent stalling on downshifts. One morning I get my bike ready to go to work, turn the key, flip the switch, engage the starter and *Bzzzzzt*. The noise wound down more with each press and the lights dimmed darker and darker.

I assumed it was a low battery, so I kicked myself for not using a battery tender and bought a small duracharge from cyclegear. The bike is used and the previous owner hooked up the tender cable so I just plugged it right in. After 2 days of charging the light turned green. Excited, I unplugged everything, got my keys and turned ignition to on.

Everything looked good. The lights were on and nothing appeared amiss. I flipped the engine switch and pressed the starter button. The moment I hit that button the bike made some loud buzzing/popping noises and all the lights went out. I was pretty bummed since I had just spent 2 days waiting for a charge. My first thought was that the main fuse went out so I got into the starter relay and pulled the fuse. Much to my surprise the fuse was perfectly fine.

I am a complete novice when it comes to bikes in general, but it appears that the battery has a fill line and there's no fluid inside. I also noticed the breather vent and it seems the hose came off some time ago. Battery acid looking corrosion is all along the side of the battery.

To make matters more confusing, one device does seem to function. The previous owner installed some heated grips directly to the battery. When I turn the key, the grips function perfectly and the heat settings can be toggled with no problems.

What could be going wrong here!?

Thanks in advance, everyone.

Welcome to the forum.

I experienced this exact condition just recently with another dual sport that I have. I had previously run some additional circuits for accessories on the bike and then a couple months later, the condition arose. Essentially I turned the key on and everything lit up fine. The minute I hit the electric start button, everything went dead while making some unusual buzzing noises. When I started that procedure over again, it did the same thing. I know my battery is good. Popped the seat off and the positive terminal on the battery was hot. It was a short and it turned out to be in my accessory wiring. Fortunately an easy fix. Maybe first get all the accessories disconnected and see if the condition persists. You can always reconnect them later, and perhaps improve the circuit in the process.

The battery is pretty old so it wouldn't hurt to replace. As for the short circuit concern, I'll be unhooking my two accessories and trying again to see if I can get the electrical system to work. I really would be disappointed if I had to hunt for frayed wire.

Thanks for the tips, guys.

Without electrolyte covering the battery plates, the battery can only deliver insufficient current, regardless of the voltage after charge.

Your battery may be shot, maybe not. Top off the cells, charge it, and see (my recommendation).

If you can jump the battery with a known hot automobile battery and start the bike successfully, then . . . chances are, something's amiss with the motorcycle battery.

Has your bike had the wiring harness rub through recall done on it??

Hey everyone!

I thought it couldn't hurt so I bought a new OEM equivalent battery from cyclegear. It checks out on the multimeter but I'm hesitant to install it.

The duraboost charger that I had previously used on the old battery doesn't seem to light up when I connect alligator clips or terminal leads! Could the old battery have fried the tender? Perhaps it was defective for some reason.

Heading out now to exchange the charger just in-case.

Nope, I am not familiar with that recall. Where can I find details?

Use the Forum Search function and you will find the info. This is probably the best thread on it. Post #13 has pictures.
