Over the last two days I removed an old bathroom ventilation fan that also had a heater and replaced it with a fan-only unit. The old fan and heater were run separately from a double switch, so I hooked the new fan up to the same black wire that powered the old vent fan (top switch in bathroom) and capped off the red wire that used to power the heater (from bottom switch). And attached white to white as had been before (and the ground wires on their own too). On the same circuit is the bathroom light. But that is all that is on the circuit. Bathroom outlets are on a separate circuit. After hooking up the new fan the old fan switch turned on the fan, the old vent switch was ignored, and old light switch still turned on the light. Everything seemed fine - so even though I still needed to do some ceiling patch work I let my wife use the bathroom to shower, etc. No complaints. Then I went in later and no power to anything. No fan, no light, nothing. Circuit breaker is still in "on" position. Tried flipping it off, waiting, and back on. But still nothing. So back to the attic and checked the connections in the box on the fan unit, all okay. Checked the connections on the switch units in the bathroom, all okay. As for those switches - it seems that the power comes into the double switch units and from that switch unit a black wire transfers power to the separate light switch unit. Anyway.. no juice at all. Only thing I can think of is that my circuit breaker fuse is blown? But if so, why? And how can I test that? What else might be going on to knock out the whole circuit? Thanks in advance for your help. DH

Hello, I'm trying to install an RV water pump into a food trailer and am a real beginner when it comes to electrical stuff. I will try my best to describe my question. Right now I've got a water pump that is intended to be hard-wired. The food trailer that I'm going to install it in only has standard three-prong plug outlets though for power. I went ahead and bought a plug connector at Home Depot (pictured below) that can take up to 15 Amps and 125 Volts. The water pump is rated at maximum 7 Amps, 12 Volts. My main question is about the wiring. The water pump has only two wires, but most of the power cords I see at Home Depot have 3 or more wires. What would be the recommended way of hooking up the water pump into a plug outlet? Could I buy a small power cord from Home Depot and just ignore the unused wires? Thanks in advance [ATTACH]28103[/ATTACH] water pump: [ATTACH]28104[/ATTACH]
