Little background about the bike. I bought it in June, rode it a few times then went to Afghanistan the end of July. Came back in October took it trail riding and the bike ran really hot and starting making some weird metallic rattling noises on hard accelaration. apparently it hadn't been rebuilt properly prior to me buying it.because my mechanic tore into it and nothing was torqued properly..piston pin ended up elongating the hole in the piston to where it was cockeyed in the cylinder, clutch hub and basket were notched so bad I don't know how they were in one piece, etc, etc. Now for the problem...I have ridden the bike 3-4 times since the rebuild with no issues until Saturday while riding up an easy hill climb the bike just bogged and died like someone was holding the kill switch. I had been riding for a couple hours and had a spill earlier in the day but the bike seemed fine until it died and hasn't started since. I made sure the bike wasn't out of gas and then started pushing it back to the truck. Got it home and pulled the plug and could tell there was gas in the cylinder so I checked and the plug isn't getting spark. Upon closer inspection I noticed the ignition coil was melted...see pic: My mechanic thinks this could have been from when the bike was overheating or from a short of some kind but either way it looks like it caused the plug to arc on the head and possibly short something else out. I replaced the ignition coil with a new one from my local dealer and still no spark. I had a buddy with a meter start helping me test the resistance at all the connectors and we aren't getting anywhere. In the plug on the right side of this diagram we were getting "open" readings where it shows we should have resistance: My buddy thinks this means my magneto is bad but looking for help and ways to test the magneto or any other suggestions. Sorry for the long post, I am just at a loss with anything electrical.
