So here's the deal. I crashed my 06 F4i about 5 months ago and have been slowly rebuilding the front end, as that was where the only physical damage was. Fast forward to today, I have new forks, tire/wheel and radiator. It was a head-on collision. Being the noob that I am, I left the battery in the bike, attached. It is now dead. I have since charged it to the point where the bike will turn over, sound as though it wants to start and then won't. I will let the bike sit for a day, come back to try and start it and it won't even turn over, as if the battery is dead again. However, when I go to charge it it shows that it's fully charged. So my question to you is. What could possibly be the result of a slowish head on collision (about 30 mph) and the affect on my bike, preventing it from starting? Assuming it's not the battery (what kind of multi-meter should I get to test), I've read it could either be the stator or rectifier/regulator. Any thoughts or experience would be extremely helpful. I do have a Haynes Service manual to help too... Thanks!
