Confusing electrical problem
Hi everyone, this is my first post and I actually joined the site a few days before this happened, good timing in my mind.
First of all, I do not know electrical systems. Mechanical side I am so-so, but I have no idea about the electrical. To the problem: Bike was running fine day before. Went out in the morning, turned the key and oil and neutral light came on as usual. Pushed the starter and there was a pop (electrical sounding) and the engine did a half turn. Now the lights were off. I turned the key off and then on again and there were no lights. I thought fuse, but checked all of them, all good (at least all the ones on the right side fuse box, including the 30 next to the box). Disconnected and checked battery, holding 12.38V, reconnected battery. So I bump started it. Here is where it goes weird. Once it started the tachometer was reading 8-9K and bouncing around that area. The engine was only doing 3-5K judging by sound. All lights, including headlight were really dim. I was sitting there confused when I grabbed the front brake. As soon as the brake lights went on the engine and tachometer went to the normal ~2k (it was cold so choke was on) and the lights brightened. It did the same thing with back brake and found that the solution had nothing to do with pressure on the brakes, just the lights activating were making the difference. While the brake was activated I still couldn't get it past 4K rpm without the tachometer bouncing around. Any thoughts? Like I said I don't know electrical systems (but I am a quick learner), so if all your wisdom can't help I will have to take it in. Thank you, TJ |

Agreed, bad battery connections, check both grounds, and the connections at the starter solenoid.
Don't forget to report back, dismissed

Once you've done that, if the problem still persists, you can take a screwdriver and touch it across the two big terminals on the top of the starter solenoid, this is how to bypass it for testing purposes. You might need a new solenoid, no worries they not expensive http://www.amazon.com/Starter-Soleno...+250+1986-2010 I have this exact one, 4,300 miles and no issues whatsoever.

Well it is fixed. Turns out that while the battery was holding a charge, it was actually dead. I did not know that could happen, but reading through the links that Motofool provided I decided to jump the bike with my car. I was able to so I ordered a new battery. Just got back from a trip and was able to install it. Started right up. Thanks everyone for the suggestions, I now have nice and clean connections

I learned the same lesson once. If you monitor the voltage while cranking it will tell you what you need to know.
