The ignition amplifier is bad or the connection is corroded.
The part is easy to get to, and is easily replaceable, but I would not suggest trying to test it yourself unless you know how to use a voltmeter.
If you want to replace it I would first buy a Haynes manual and follow the instructions (they have pictures)!
Good luck!
