Won't Start - No Panel Lights

[AzBill]

I just bought a used 763 with less than 2000 hours. It's ran great for the last couple of months. Just recently the panel lights and associated beeps will occasionally not work hence it won't start. If I shut the engine compartment door firmly it will miraculously light up. Anybody know what's going on? Thanks!

Relay with bad connection or dirty battery cable, Check them on both ends.

I cleaned the battery cables when I put in a new battery,..... I'll check the relay. Thanks!!!

Check your fuses too, the connections have a habit of corroding and causing issues. If they are bad, find the problem one and replace it with an inline style one.
