Title: Wiring layout
Post by: Shacklepin on July 14, 2010, 08:41:39 PM
Has anyone got a wiring diagram for the the Pearson 365
I know where most of it goes but I'd like to know where it's supposed to go so I can bring her back to sanity :-\

Wind Tamer had the original manual on board... plus it's also online somewhere here about in the website.

Pretty sparse on electrical, (nice bonding diagram though) and you probably have the work of previous owners to further clutter what should be there.

Good luck, I've stripped out enough wrong wiring so far, to completely wire another boat. And, I'm not even half through.

My problem is I'm trying to sail every chance I have... so have to work one issue at a time.

If I was on the hard would strip it all out and start fresh.

Thanks again Slokat. I'll investigate the site further. I have only just started to tackle the electrics. I cheated a bit and got Lakewood yachts to completely rewire the engine so she now has her own starting battery independent of the four house batteries so I can run all the onboard electronics till they die and still start the donkey downstairs.

That's one of my upcoming projects, when I decide where to put the starter battery.

Right now it is stored in the main salon for a jump start, if needed.

Where did they mount the battery for you?

What batteries do you have now. How do you wnat to charge the starting battery. The new style is to use a voltage sensitive relay that puts the starting battery in parrallel when the charging voltage of 13.7 volts is applied. You would need a seperate switch and the smart charging switch. Just Identify the heavy lead going to the starter and run it through the new main switch to the new battery. The smart charging switch goes between the starting battery switch and the house battery. When I run this system I use a 2 way main swtich for the starting battery switch and connect the #2 side to the house battery for a backup.

Mose of the wiring in the P365 was very basic. The problems come in with the additions that previous owners have installed. I may have an origional diagram. I will look for it.

We have a pair of 100A battery combiners so that we will be able to charge the windlass battery too. These are what we have:

You can go to Defender's site and plug in combiner for a search. There are lots of options.

Hi there fellow Pearson-ites
Ebb Tide is well appointed electrically. With an Air-X wind generator keeping the supply going, I have two banks of two Odyssey PC2150 gel batteries, Two are high up on a shelf in the Starboard locker end to end and the other two are as low as they can go side by side at the forward end of the Port Locker, just giving me enough room to get at the Racor filter unit which is in dire need of replacement.
The independent starter battery is lead acid [type unknown] and sits in its own container, outboard and above the two house batteries in the Port locker. As for the wiring even a demented silk worm wouldn't know where to start.
As for the 'V' drive I decided, as discretion is the better part of valor, to removed the engine drive shaft to find a cavernous void within. There is oil on the dip stick but stick a finger in the drive shaft hole and there is nothing, not a whisper. in the process of removing the associated hoses one of the Bronze elbows sheered Grrrrr.. but thank goodness because it showed a weakness that could have been catastrophic / expensive at the wrong time.  Also one of the wire wound hoses came to a sticky end and will be replaced.
Does anyone know if the gizmo that is in line from the 'V' drive to the Raw Water Pump is a check valve or something else?

It should be a seawater strainer.

Hi Ray,
My Raw water strainer is mounted before the gearbox. The device I'm referring to is about 2ft up the line and apears to be three screwed components, in line, and looks like a pipe bore reducer yet the hoses connected to both inlet and outlet are the same size. In all it's no more than 3ins long. Next time I'm onboard I'll take a photo.

If you have a hydraulic transmission (Velvet Drive) it's probably the hydraulic fluid cooler.  You should be able to trace the the supply and return lines from your transmission to the cooler.  If this has never been replaced you can find the proper model from Sen-dure (http://www.sen-dure.com/).
