Ignition problem

[Wizard914]

Son in law has evinrude 1986 100hp new boat to him. Ran good untill fuse blew then no engine power.found fuse and replaced engine turns over. He took apart throttle controls and found bare wires after replacing fuse ignition switch sparked and caught fire. Now engine turns over but no spark to plugs.
What test can we do to isolate problem.
Thanks for clues on how to diagnose.

You have a direct short some where. The hot wire is grounded out,probly in the wireing harness.

You can use a volt meter to check the wires.
