If the side stand switch stops the engine then it sounds like it's working. Looking at the drawings there is a diode between the neutral light and switch, so if water or a damaged wire was earthing the lamp (therfore lit) between the lamp and the diode then the switch would work and stop the engine but the lamp would be always lit. Sadly can't explain why it went out when the engine stopped though. I'll keep looking so let us know if you get it sorted or if it sorts itself.
