Hello,

Thank you for allowing me to assist you, my name is Joe and I will be happy to assist you with your concern today.

The most common cause for this happening if then lack of power to everything else is a poor/bad ground or power connection. This can include a dirty connection, loose, damaged, look at mainly the engine/battery ground to start and at starter solenoid, turning the key and trim are both higher amp circuits which leads me to my included info on connections. So let's start there first as again that is the common problem. Note this can include bad wires/cable such as main ground cable.

Thank you!
- Joe
