Any suggestions on a probable cause for inop NAV lights? I have LED Nav lights. None of the NAV lights are working but the landing lights and strobe work fine. Checked circuit breaker and did a reset and still not working. Is there a power supply for NAV lights other than the battery like a strobe power supply? Thanks

Ground wire? Do you have an ohm meter?

There's no power supply for nav lights, other than said wire to the light. Most common issue is corroded or broken ground at the light.

All inop? Then I would start testing for voltage after CB and after switch from switch should be straight out to lights. Individual inop start with grounds.

What Hammersmith said...^^^^^^^
But start with the wire coming from the buss to the nav light CB in case there's a loose connection there...
I'm betting on bad switch.

Thanks to all who responded. The multimeter is your friend! The switch is bad.
