The bulb may have fallen out of the fixture, otherwise you might need a class light harness. Of course, knowing the exact model would help identify what you have.
Winner, winner, chicken dinner. You guessed correctly John. I disassembled the boiler cover, removed the lantern to test the harness. It all lit up. Reassembled in reverse order and I’m back running a repaired engine. Thank you again.
When I get to my passenger coach upgrade, I’ll get your led kits.
