I have 2 cabin lights not working. Bulbs are good. I tested the socket with a volt meter and read 12 volts. The lights in the head and spot light over the bunk both work. Has anyone run into this problem?
-- Misdiagnosed the bulbs
-- Read your meter wrong
-- Corrosion on bulb or base contacts (but the meter probes poked through it)
-- Failing wiring/corrosion can allow voltage to read properly, yet not pass enough amperage to light the bulbs
See above. Use a contact cleaner for electrical circuits. Buy new bulbs and give it a whirl . You could pull down the socket and inspect the wire connections.
test the socket on and off - ensure the voltage comes/goes.
lightly sand connection points (bulb and socket).
install new bulb.
once they work, put in some dielectric grease used on auto lamps sold by auto stores to mitigate corrosion.
