Nav Lights popped 5A circuit

[jaciii2]

Prior to taking it to the shop, are there any 'trick's to find a circuit gremlin? Nav circuit popped this weekend, I have 2 tail lights (T-Tail Lance) that are incandescent and two wing tip LED strobes/Nav on the circuit in addition to the original panel lights. Rarely if ever fly at night, but often have the Nav lights on. No changes in the last 18 months - had 2xGI275 and GFC500 put in that required the LED's on the wings. This may be a big question, but are there any tips to find the issue quicker? Looking for any/all ideas.
