Hey all. Long time since I've posted anything. Now that it's spring, the Airstream is back in the driveway, and we continue making it better, one demolition at a time.
In removing the counter, I discovered that the old water pump behind the stove was still there, even after the dealer installed a new one in 2009. (It was tricky to get to, so I certainly don't blame them for not removing it). So I removed it. (here's a picture)
Anyway, to my question. I wanted to re-locate the new waterpump to the platform that the old one was on, to get it out of the way, maybe cut down a bit on the noise, etc. When I moved it, I discovered:
a floating black wire. So, the blue wire comes from the great big wiring harness, and has an inline fuse on it, switches to a yellow wire, and goes into the water pump. Then, there's a red wire that comes out of the same place where the yellow wire goes in. That goes to the back of the pump, and a black wire comes out of there. That black wire was not attached to anything. I'm pretty sure it's a ground wire. Should I just attach it to an area of the wiring area that seems devoted to ground wires? (there's a board attached to the skin with several screws. One screw has the ground from the univolt panel on it. Another screw has the ground from the battery charger on it. There are several other screws available. Should I just use one?).
I have the main fuse supplying power to all the 12V
stuff (furnace fan, lights, radio, pump) pulled, so I am not in any imminent danger of electrocuting myself, but I'd like to keep it that way.
Your attention is appreciated.
