I have a 6 volt quartz halogen bulb from a torch, which won't light when 6 volts DC passes through it, but will light up with 2.5 volts AC.
Any ideas as to what the problem might be??
I need to replace the thermostat on a Concord wrs boiler which is located in an awkward position. Does anyone know the model of thermostat required so that I can purchase one before I attempt to remove the cover from said boiler.
Thanks
