Good evening,

If the light goes out, it is not the security system at all.

I attached a diagram of the starting system for you to view. We need to do some testing at the relay.

Check all your fuses with a test light to see if any have failed.

Hopefully the only damage you did was blow a fuse.

I would check every fuse in the fuse block.

I attached the diagram of the fuse block for you to view.
