Re: Light Switch Controls All Downstream Connections
Do the downstream lights seem dimmer than normal? Even when "off" does the fan turn, slowly? If so, it could be that someone wired in the downstream lights and receptacle by just tapping in to the wires at the switch, without a proper understanding of electricity and wiring.
So when the switch is off, the lights and outlet are wired in series with the fan -- that is, the electricity has to flow through the fan motor in it's path through the lights. When you turn the switch on, it "shorts" the lights & outlet, so the fan turns at full speed and no electricity flows through the light.
It seems a bit far-fetched, since a fan typically has a lower wattage (higher resistance) than a light bulb (lower resistance). If this were the case, I'd expect the fan to speed up as more lights were turned on downstream, and each light added would make the other ones dimmer.
