how I can solve the problem. what eccesoriess to chec

 

A good starting point would be to check all the fuses. Very easy to do with a test light or voltmeter. If you find one in the ign supply circuit that has opened , you can replace it with same size of course and if it blows again there is a short to ground somewhere in the circuit.
Make sure the ign switch is working properly by sending power to systems when in the on position.
