Fuse Box - Fan Smell
I have discovered a smell which seems to come from the electric fan next to the fuses under the sink on my Excella 500 1973. It only occurs when the unit is hooked to the house electric. It does not happen when on battery or on campsite power. OK sounds strange I know, but has anyone had similar. the smell is sulphur dioxide.
Does the fan only work when its on low volt shore power, why didnt it smell on the 30 amps smell, is it on a thermostat - therefore when i had air conditioning running it didnt click on. so many questions.
I now have to replace the water pump, I am eagerly searching this site for a how to guide for my model. If anyone knows where it is located that will be a good start. I remember the pump making a whirring sound from somewhere undeer the sink, but all the plumbing stuff seems to be under the rear bunk, a mystery to me as i am not that technically minded, you may have already worked that out.
