Motorcycle Repair: 1984 Honda Magna V45?coil bad?, honda magna v45, 1984 honda magna

Question
My Honda Magna V45 is not running well. The Tach, Fuel Pump and Fan just up and quit suddenly on me while driving. It was driving fine until then and happened with no warning. It will run if I keep the throttle open but will die out shortly if I let go. Also, it sounds like it is only running on a couple of cylinders now. I was wondering what you think I should check?  

Answer
Lee, if all the sysmtoms are correct i would start at the fuse box and work my way thru the wire harness, get a manual if you dont have one and check the wire diagram and follow all leads and try to find the break. also check grounds to frame.
