A couple of quick questions for a 2003 GulfStream Sun Voyage

[mgideon]

I just took my maiden voyage with my new to me 2003 Gulfstream Sun Voyager 8378. I came from an older simpler National Tropi-cal. I have couple of quick (and hopefully simple) questions.

1) I haven't used the water pump prior to this trip. There is a foot long hose connected to the city water connection. When I was putting everything away from our trip, I disconnected the city line, switched the switch to the fresh water tank, but when I ran a faucet, I noticed the water was shooting out the fresh water hose inlet. Do I need to cap that? There is a cap, but it wasn't connected when I attached to the city water. I would guess the switch would keep the water from coming back out. Do I need to cap that line (hose in this case)?

2) Again with the fresh water; My gauge shows the water is empty. I went to the other side and found the take and visibly confirmed the water level was above the top sensor, so it should have shown at least 2/3 full. Is there some maintenance I can do (clean contacts or something) to get this working again?

3) Both holding tanks show half or more full after dumping. I flushed both out a few times hoping to clean the sensors. Does anyone have a way to get those working like they should?

4) Last is about the generator. I had it running while we were driving back to keep the air conditioning running. About an hour into the trip everyone was complaining how hot it was. The generator had stopped. I don't know how long it had been off. It was noisy driving down the road so I pulled over ( it was still a bit noisy) and tried to hear it start. I couldn't hear it even turn over. The compartment door would not open from the outside even after unlocking, so we just left it at that point. When I got home I tried it and saw the light flicker as I tried and heard it turn over. Is there some issue with the generator running while in motion?

Thanks in advance,
Mike

oh wait! I have another

The ice maker was VERY slow. It seems to give one tray every 3 or 4 hours. I have a portable icemaker that makes a tray every six minutes. Is that normal? There wasn't a lot of frost. Water bottles in the freezer were freezing overnight.
