Motorcycle Repair: 1994 yamaha yzf 750, yamaha yzf 750, power fuse

Question
batery was dead so i jumped started it....and drove it down the road then it backfired and turned off. every since then it wont switch on....i bought new battery but when turn key switch on nothing happens. i checked all fuses and all are good. what wrong?.

Answer
Its hard to tell.The battery may have gone bad. When it was replaced the main power wire may have been pulled loose.Its still in the connector but in may not be touching. Check the main power fuse with a test light to see if there is power to both sides of the fuse.
