I added a schematic.Which relay?
16 V AC or DC?
Is the voltage present when you remove the lamp?
Show us a schematic.
WHERE?when I open the lamp, there is a voltage
What do you mean by "lamp is open"? Typically a fluorescent lamp has a starter in parallel. This starter has a built-in capacitor which in turn is a capacitive impedance. A small current through this impedance will show as a voltage reading on your multimeter.Be careful when the lamp is opened, there is also a voltage of 16 volts.
You can't expect good answers when you don't show us the real circuit, can you?MY LAMP IS Fluorescent lamps.
Did you remove the complete lamp including the starter? If you only remove the lamp from the lamp housing there is still the starter with its parallel capacitor.Note that when I remove the lamp, it is available at a voltage of 16 V
See post #6. The op has indicated the points of measurement as crosses and a dotted line.Indicate where you are measuring the voltage>
Over the years I've seen a fair amount of leakage due to flux residue on the boards. If you use old school rosin core solder, (like kester 44) it looks pretty ugly, but the residue has negligible leakage. Many of the newer fluxes leak a LOT. They are designed to be washed off alfter soldering.
