Common guys. Where is the circuit board in a PS-2 3V Engine? If it is in the tender there is no LNB. There is only 1 Light wire going to the engine and it is muxed to control 2 features. HL and IL. Markers by default off the lights. Typically IL and Fire Box on the IL circuit. So HL would probably have the LNB, though they could have put 4 bulbs on IL FET. Since his HL and IL work, the only reason for LNB to be out is a broken wire or both bulbs burned out. Sound file is not the problem. G
