First determine if you have spark. Pull a plug wire off and insert a spark plug in the wire. Lay it so it touches the engine. Crank the engine and see if there is a spark. If not you have a problem with the ignition system. If you have spark but it won't start you may not be getting fuel to the engine. I have not worked on a 2010 but I suspect the gas tank has a valve that is actuated by the engine. No engine RPMS to create a vacuum, the valve stays shut. When the engine fires, the vacuum opens the valve and lets fuel flow. Once in awhile the diaphragm in that valve fails so the valve cannot open, no gas, no start. Try the spark test first in an attempt to learn more. Then address the fuel issue if that proves not to be the problem.

Maybe the dealer will tell you. I don't have any resources for that. My old 2000 manual doesn't even address that. Just call the service dept and ask for help. They should be willing to give you that little bit of info over the phone. But have pen and paper handy. There might be several steps to it.

I recommend to anyone wishing to do even minor work on their own Harley, buy the shop manual. With clear instructions I have been able to do a lot of work that would have cost more than the manual. Since the year 2000 I have replaced seals in the front forks, brake pads, and done all the oil changes myself which I know would have cost a lot more at the dealer. The manual is very detailed and gave me the confidence I could do those things safely and not have to worry about something going wrong on the road. Now about the spark plugs. Gap them at .040, use locktite anti seize and torque to 15 lbs. Tighter and you risk stripping the threads, they are only aluminum. Looser and they may back out. Ride safe, ride longer.

Are you suggesting the negative battery cable melted? If so, did the engine turn over when you hit the starter button?

A faulty bulb or electoral connection will cause this fault . There is only a light load on the flasher unit with rear light out . causing the front light to flash fast.

depends on the state of the battery , The regulator looks at the battery charged state and regulates the voltage to fully charge it , If the voltage does not drop back after a few hours the battery could be on the way out.

Air coolled and not liquid cooled it would be limited to condensation and not allowing motorcycle to get up to full operating temperature.

ck. the INNER PRIMARY BEARING located behind the clutch assembly.

could be bad key switch

I would as well. I have never seen a troubleshooting guide for electrical wiring on a Harley. I've got a shematic for a Softail but no trouble shooting guides. What are you having problems with? Maybe I can help.
