53 Electrical Schematic

[oscarvan]

Can anyone point me to, or email me an electrical schematic for a 53MY? (1978 if that matters). Need to get a head start on my systems studies.....

Thanks.

Have the bull ID number handy when you call hatteras.

They can sell the whole manual including wiring diagrams for under a hundy.

Are you looking for something specific?

Call Sam’s , get the complete “grey” box. This includes all wiring diagrams AC and DC .

PM your email address and I'll forward them to you in PDF form. They are too large to upload. I have 32v and 120/240v plus a few misc ones. I'm happy to share with anyone that needs them.

Not looking for anything specific, just need to understand its architecture. I'll get everything SAM's will sell me once I own the boat. For now I just want to get a head start.

oldlaxer1, pm sent. Appreciate it.

I bought mine from SAMS when I bought the boat. They are decent schematics and accurate (I have a 1978 53). However, they are just schematics, not architectural diagrams of wire runs.

Some guidance...

Shore Power - 2 x 30A/120v or 1 x 50A/240v, Port and Starboard

Generator - Located beneath galley

Source Selector Panel - Select between shore (30A or 50A / port or stbd) or generator

AC Breakers - Everything (including HVAC) is 120v except Stove/Oven and Washer/Dryer. Many of the breakers are just 15A, especially those that feed strings of outlets. Specific breakers, like the stove, dishwasher, etc, are sized accordingly. There are 5 spare breakers, 3 x 120v and 2 x 240v, prior owner may have used them.

House Bank - Port bank supplies 32v

32V Breakers - In most places where there is a 120v light there is also a 32v light. There are additional places where there is just a 32v light. The water pump, toilets, trim tabs, starters, instruments (via Newmar converters) are all 32v.

Newmar Converters - there are 3 Newmar converters in the helm console and 3 in the flybridge console. These are low amperage and supply 12v to all of the instruments and instrument lights. They may have provided power to a radio, but definitely not to the old electronics that originally shipped with the boats. I removed the original DECA radar, and it looked like it would need its own generator.

Electronics - Depends on the owner, but generally these are run from the 12v battery in the generator room.

HVAC - 4 compressors feeding 6 air handlers. One in the aft salon, one for the fwd salon and galley, one for the guest cabin and crew cabin, one for the master cabin. HVAC is all 120v.

Outlets - Almost all outlets are on one of three 15 amp breakers. One for port, one for stbd and one for the galley. The appliances are on their own breakers, including the disposal. The lighting is on a couple of dedicated breakers, and the charger is on its own breaker. Each HVAC compressor/air handler is on its own 30A breaker. The HVAC water pump has its own breaker. The scheme works mostly, but it is easy to trip an outlet breaker.

The breaker panels swing open and are generally organized well.

There is no isolation transformer on my boat.

The wiring on a boat can be very convoluted, and you will simply have to follow it. Much of it is inaccessible, though the endpoints are generally accessible. Beyond the breakers there are additional fuses for the whole boat, located in the engine rooms. These are the old slow blow paper fuses, but readily available from Home Depot. For the most part, dealing with the wiring (120v and 32v) hasn't been too challenging. You will be overwhelmed at first, but after some time you will get used to it.

Appreciate that. I got my head around my 40 foot diesel pushers systems with multiple 12V and 120/240 systems so it doesn’t sound too daunting. Just a matter of figuring what powers what.

Sounds like a commercial pilot to me...I need to do the same thing.

Send me your email, and I’ll forward all of the schematics I have.
