Re: k1200LT electrical problem
Given your skills and your available test equipment a good test would be to charge the battery up and then go for a drive. When you get back remove the negative terminal(s) from the battery. There should be only one if all is stock. Then just hook it back up next time you want to ride. There will be arc's as you call them when you do this and that is normal. If the battery does not start the bike then the battery is bad. If it does start the bike then you have something pulling the battery down.
Now is when having an ammeter would be handy. If you have a Harbor Freight they usually have multimeters for less than $10. Once you get one you can then track down what is pulling the battery down. Place the meter on the highest "amp" scale and connect it between the negative lead and the battery negative terminal. After the initial "arc" the meter sould only read about 5 milliamps of current. If it does not then start unhooking things added to the bike and then pulling fuses like New2rt suggested.
Also it is a good idea to always shut down the radio before turning the key to off. Then turn the key to "lock" to shut down all accessory driven items.
