I got the bike (Cagiva Mito) a couple of months back, 2nd hand (2001 model, 8500 k's). From that time, the battery had been a bit weak... sometimes it would be too weak to crank the bike so I'd roll start it. I tested the voltage on the battery, it was around 12V, rising to about 14V when revving. With a booster charge up, it held up until last week. Friday night, it refused to crank over at all and at idle, the lights would dim and it woul dtry to stall. I had to prop up the revs at the lights. The headlights on and dodgy front brake switch forcing the brake light permanently on didn't help. The battery was reading 11.7V when off. Okay dead battery, time for a new one I thought. It's probably the original, 6 years old. I bought a new one and filled it with acid, let it sit a couple of hours and charged it for a full day. (I'm wondering if the charger did anything at all, because it read out 12.6V before and after). So the bike started and ran fine for a day or two. Then today, it's too weak to crank the bike and I'm getting the dimming at idle problem again. Measured the battery when off, it's 11.6V When I rev the engine, the highest it goes to is about 12.9V, and it actually starts to drop above around 8k RPMs? I've plugged it in to the charger again, though I think I'll train it in to work tomorrow Is my alternator shot? Is it possible to get wrecker ones? I got quotes some time back just in case, and new ones were around $600 >_< Have I killed my new battery? Could all of this be caused by the brake lights being on? More bullshit stuffing around this weekend instead of riding Any help appreciated!! bj.
