I am in the process of upgrading the wiring on my P42 to support 600 watts of solar panels. Can anyone point me to online electrical drawings of the DC circuits? Thanks

The first task is to go through and label both ends of each cable. Something that should have been done at the factory. The second is to stop using the battery posts as buss bars and install some proper bars. Third is to figure out how things were intended to work vs how they are wired now.

I would appreciate any help or pointers to past threads.

Had the same problem when I installed a Link 1000 several years ago. Made a buss bar out of copper from our local metal supply house. Wrote an article with pictures that can be found in the Boat Info tab. That cleared the battery posts of all those ground cables. Hunter 42 Owner Modifications and Upgrades

The P42 wiring system is well above my pay grade, but works just fine. Unaware of an online wiring diagram, but I have done quite a bit of wiring on our boat over the years. No solar panels needed here thanks to our 8KW Genset.

Terry, good writeup on your Link project. Inspires me to move forward.

Maybe you can offer some insight on specific issues.

1) I want to verify that the DC cable upgrade/recall was done correctly. Was your boat involved and do you still have the instruction sheets?

2) I am trying to understand the two mutually exclusive main DC panel breakers labeled “Available Source 1 & 2”. I assumed this meant the panel would be powered by bank 1 or bank 2. Even though I have removed Bank 1 to trade it in for a couple of GC2’s, both breakers show available power. The A/B selector switch is on bank 2.

I have the same generator. The only limitation is that it needs diesel. On our trip down the Exumas we stopped at island after island to find they were out of diesel, as well as milk, bread, fruit, etc. The supply vessels had not come in a couple of weeks. Even if you could find it, diesel was $6 to $7 per gallon.

This is my practical requirement, to have drinking water and a functioning boat without diesel, but I will admit I am looking forward to first hand experience with solar. I also considered going to lithium batteries, but at $1400 versus $400 for the same amp hours in GC2’s, I think it is too soon. LED light bulbs were $10, now they are $1.

Thank you. Yes, our boat was covered by the recall, which was done back in 2002. Doubt I can find any of the paperwork, but will check my files. As I recall it involved replacing the wires from the shore power plugs to the main panel with a heavier gauge. Everything else Is pretty much original and I've made no changes other than adding a few circuits here and there.

Plenty of diesel around our cruising grounds. The 70 gallon tank provides plenty of capacity to get around. Diesel in British Columbia prices higher than in the United States, but not near what you reference.

The only big change was replacing the original wet cell 8Ds with AGMs. Higher priced, but not at the level of Lithiums. Been very happy with the AGM performance. Plus I've always kept the main panel switch set on BOTH.

I am not aware of the AC wiring recall. The one I am thinking of has to do with replacing battery related cables in the engine compartment with much heavier gauge.

Now that you mention it, I think you are correct. Unable to find any paperwork from the recall. Hunter paid for all parts and labor.
