My son bought a 1984 KZ550LTD as a first motorcycle to learn to ride. Not gonna lie, it has seen better days, but it was running and it was cheap. It was good for a time, but now it's behaving strange. After it's been running for a while and it's good and warm, it stalls suddenly. There's a loss of power, fuel and oil lights come on, engine stops. At this point all electrical stops working. No lights, no ignition, nothing. Battery is measuring 12.65V. After a brief wait, the lights just come back and everything works again. The engine starts up and it can run for a little while before it stalls again and electrical is off. It seems to me that something is getting hot and disconnecting until it cools down sufficiently to reconnect, but what? Is there a computer on this thing? The oil light doesn't come on before you start the engine, but comes on before it stalls? The fuel light also comes on before it stalls but it has plenty of fuel. Aren't these just simple circuits that can only work if the sensing switch closes? I really need some help here. What is there other than a main fuse that can cut off all electrical power? I've never heard of a self-healing fuse.
