"I discovered that even though the pump is wired to a switch at the helm, it was fused through a fuse in the battery box in the starboard lazarette. Why - I don't know. Had extra fuse space on the panel at the helm "
The bilge pump is usually wired directly to one battery with its own fuse and switch and does not go through the main battery switch or the helm fuse panel so as to allow the pump to be left on when moored without having all the other electrical/electronic circuits activated. This of course, is to allow for rain water or leakage removal without incurring all the hazards of leaving the rest of the circuits activated.
Sounds like you had a great day on the water! Joe.
I agree with the theory above and that bilge pumps should be wired that way - however, there is a switch at the helm in the std. factory wiring allows one to turn the pump completely off at the helm. Given that the wires were run to the helm and given that most of the other fuses are up there AND are better protected than in the lazarettes, I would think it would have made more sense to either use an open spot on the fuse panel or to put an in-line fuse up there. That's certainly the first location I would (and did) look in for a fuse.
Also, I know this has been touched on a few times before, but the factory wiring job on my boat is a bit of a mess to follow and is not well documented. One of the things I think the factory needs to work on (Jeff are you listening) is to standardize the wiring that can be standardized, and to more clearly document the wiring in both the manual and on the boat. It's very difficult to trace what looks a bit like a rats nest after installation when wiring is not labeled and well documented. Also, I think the process of standarardizing certain layouts would make it easier for the factory to:
1)bring on and train new staff
2) repair and service boats from customers and
3) Communicate with customers
By standardizing, I mean that wiring which is common to most or even many boats should be run the same way and fused off the same panel position on all boats. That is anyone who has the std. single bilge should have a fuse in the same clearly documented location, ditto for the galley and table lights, the wallas, the norcold, the wipers etc. Electronics are a bit more complicated since there is large variation in what is installed but it would be possible to at least locate most electronics in a single portion of the panel and to define a typical order for the fuses in that portion of the panel - E.g. VHF, entertainment sytem, GPS, Radar etc this would not be too complicated to do and would probably require a few days of thoughtful effort on the part of 1-2 people at the factory.
Just my two cents worth..
