Electrical wiring

I have a 1983 31. The wiring has been slpiced in multiple locations through out the boat on almost every lighting circuit. It's so bad that I have had to pull new wiring to every light and now even the running lights have this problem. Is this an unusual thing, or was the Quality Assurance Inspector out sick the day my boat shipped?

Marine Grade Wiring

If the original wiring wasn't marine grade; for example, tinned, it probably doesn't matter anyway. To make a good installation it's good idea to use marine grade connectors and heat shrink tubing too.

IF

If multiple loads were designed to be on the circuit, and If the overcurrent protection is sized for both the individual loads and the wire, and If the voltage drop is within acceptable limits, and If the wiring is installed with marine grade components and marine grade installation methods, Then everything is OK.

Wiring design and replacement

My H31 is 1985 and has the same "wiring harness." After doing a little research on whether it was done by the previous owner or by the factory, I discovered the factory did it that way. (Not sure HOW it's done on new boats.) Anyway, the idea was that it is easier to run a single line than multiple lines and it is easier to attach a single line versus multiple lines to the terminal block near or on the back of the DC Power Panel. (If you power panel is under the companion hatch you can probably see how little space exists there.) Another point to support the "single wire theory" is the unlikelihood that all the cabin lights on a lil' ol' 31' would need to be on at the same time thus reducing the load required by the wire. This is why the bigger boats have seperate breakers for Port and Starboard Cabin Lights. It is far more likely that the galley, head, salon, and at least one stateroom/berth will have lights on at the same time. I have had to replace two butt connectors with the type that have heat-shrink tubing around them. The originals were not heat-shrunk on the wire and the wire corroded. I have not had any other issues with the wiring. Well, make that the "factory" wiring. Several installations of after market equipment, such as the autopilot power supply cable, were really horrible and had to be replaced with real marine grade "stuff". The Quality Assurance Inspector was probably there the day your boat shipped but he may have been looking at a different boat. Wiring sounds like it was installed correctly, but better connections should have been made to eliminate the problems your having. On the other hand, the boat is 16 years old and if your on the coast/salt water, well, this happens to non-waterproof anything. Jay

Thanks for the place to look

Thank you all for the information. When I said my wiring was spliced in many places I meant it. There was a cripm with shrink tubing in the main supply line almost every 10 inches. Almost like they ran out of wire and picked up pieces off the floor to make my harness. I know it's original work because I am the first owner. Saving grace for Hunter is my environment is harsh here in the Pacific Northwest.

Wow, that really...uh...you know

Splices in the main feed wire, huh? It boggles the mind how all of us "love" our Hunters even after we hear stories like that. Really makes me think my keel's going to fall off anyday now.
