It comes AFTER the bulb.Have you tried ringing a bell that way?What happened?Next, there really isn't a lot to that circuit.I suspect someone has possibly installed a lite bulb in the gen circuit that is incorrect for that board.You mentioned, ringing an electronic bell works?That will not require as much current as a coil bell.You also mentioned, that measuring the voltage BEFORE the circuit, produces proper output from power supply,And measuring AFTER the bulb, power drops drastically?That also could happen, if a too large bulb was installed.Maybe try bypassing the bulb for a quick test?The last think I can think of, is possibly burned or very dirty contacts on the RING button???Try cleaning the contacts, that may help???
