Pearson 365 and 367

Thanks for the pictures and the design.  The look great.
John

The wood inside is a great consideration.

Has anyone actually drilled drain holes to empty that wet area aft of the batteries and forward of the bilge?  Would that be a problem?
John

I'd love to see the pictures of where you located your batteries.
Thanks,
John

Hey folks,
Here are the latest questions:
1.  if you locate your batteries in the area just forward of the bilge, how do you avoid the buildup of hydrogen gas in that area?  The area doesn't seem very well ventilated. 

2.  There is about a 1 1/2 inch high and 24 inch wide "wall" that keeps water in this same area where several of you have located your extra batteries (under the floor board) that keeps that water from emptying easily into the bilge.  Has anyone thought of drilling some drain holes in that little wall to allow the water to more easily drain into the bilge?  What I am trying to avoid is having battery boxes sittling in 1 inch of water that doesn't easily make it over that little wall.

Thanks in advance,
John

Dear Garner,
Thank you for the prompt reply.  The pictures really help.  Would you say that the deck is about 5/8-3/4 of an inch at that location?   

Hi again,
I'm looking to add a holding tank with all the needed hardware, to replace my outworn Lectrasan.  In the process, I will need to drill a hole for the waste deck fill.  What do you all do to drill through your deck?  What kind of a drill bit or drilling tool (electric drill, rotozip, dremel?) do you use?  What suggestions do you have to avoid splintering the area on the non-skid?  Do you recommend bedding the stainless steel deck fill with silicon sealant, 5200 or epoxy?  How thick is the deck just above the forward cabin starboard locker?

As always, your wisdom is appreciated,
John

Barry,
Thank you for the pictures.  I had the opportunity to visit my boat and saw the same arrangement you have in your port cockpit locker.  Are all of your AC wires found in that port locker?  

I also found a rather sizable array of wires in the starboard cockpit locker forward of my hot water heater.  Do you have the same arrangement?  Bundled together were my DC wires along with the AC wires.  In addition, there was a breaker for the AC secured to the starboard locker bulkhead.  

I have attached a couple of pictures from my starboard cockpit locker showing the additional configuration that I have there.  YOu may notice that someone installed a 60 amp breaker on my 30 amp AC system.  I will change this out.  But any suggestions that you all my have about how the AC system is configured will be appreciated.

That will be terrific!  I look forward to seeing them.
John

Again, thank you all for your help.  It seems like I am left with no choice however, but to re-visit my boat and check the ground wires to a common point.

Perhaps I'm confused by my reading of the wiring diagram in the Pearson 365's wiring diagram (# Tp-46A).  What it illustrates is the 3 AC wires coming in through the shore power inlet cord, fused by (2) 15A fuses on the black and white wires.  The white wire goes to the "neutral buss" and the green wire is pointed to "the ship's ground buss".  That is the point that I am looking for.  When you say that the green (ground) wire is grounded through shore power it would seem then that the diagram should then point the green (ground) wire back to the shore power cord. 

I know I'm missing something.  Perhaps if I was looking at the wiring currently on my boat, I could trace the path of the green wire, say after the hot water heater; to where it ultimately connects.  But, I'm not anywhere near my boat, so I'm looking for some guidance or pictures or dialog (like we're having) in order to answer this mystery.  This is my best attempt at making my question as clear and specific as I can. 

Thank you all for taking the time to educate me,
John Manzano

You will need to find the neutral ground bus.  What are you wiring?

I am wiring a new AC control panel.  My 365 only has a shore power connection that distributes AC directly to the hot water heater, the battery charger and 2 AC outlets.  From my reading of both Calder and Don Casey, I understand that there is a Neutral wire (white) that completes the circuit with the hot wire and then a ground wire (green) that must be connected to part of the boat that goes to ground.  I understand that carelessness with this step can either create galvanic corrosion problems or possible stray current problems for those near your boat in the water.  It is for that reason that I am being extra cautious.  Although I have rewired my home, boats are another story. 

It is my understanding when you attach a device to your panel you connect the black (hot) wire to positive, the white wire (neutral) completes the circuit and the green wire (ground) goes to a "grounding bus".  On the wiring diagram for the Pearon 365, the diagram leads the green wire to "the ground bus".  Both Calder and Casey refer to this ground as located somewhere on the boat.  This ground bus is what I'm looking for.  I also realize that you either fight with galvanic corrosion or possible stray current if there is any crossing of your neutral and ground wires.  Thanks for all the input. 

Thank you for the informative replies.  This helps, especially since we are snowed in and I'm 150 miles from my boat.  Where do you all attach the green (grounding) wire for your AC, to your engine, to an exterior grounding plate?

Thanks again,
Jayman

It dawned on me while reading another book on boat wiring that I may have misdirected everyone by my use of "a/c" for "AC".  In other words, apparently, everyone refers to air conditioning as a/c and AC is used for alternating current.  Soooo, my question had to do with the alternating current grounding buss for Pearsons.  If this helps you better answer the original question below, I'd appreciate any feedback you may have.
Thanks again and sorry for the confusion,
Jayman

"Recently, I bought my friend's 1978 Pearson, which he owned since 1980.  I have only been on it 2 times to work on, so am just getting acquainted with the systems.
I have read the posts regarding re-wiring and have yet to find the information locating the ground buss for the a/c system.  Can anyone tell me where it is located?  In addition, I have read the chatter about wiring diagrams and haven't been able to find any other than those located in the owner's manual.  If you any of you can point me in the right direction in terms of where I might find a more complete one, I'd appreciate it.
Thank you,
Jayman"

Does anyone in the forum own a 365 with a Hood In-mast furling system?  I'm in the process of re-wiring it and would love to have a schematic of what's inside.
Thank you for any help you can offer.
