Hello, my name is***** sounds like the ignition switch may be defective. Do you have a voltage meter to run some tests?

Please tell me what the battery voltage is as the vehicle sits and tell me what the voltage reading does when you try cranking the engine.

Battery voltage 13.5 cluster lights go out when ignition key is turned. voltage same,no start.
Expert:  FIXITMAN replied 9 months ago.

If the voltage does not change at all then I would suspect the ignition switch. This means that nothing s coming on.
