Sorry guys my really, really busy time of year. The job I am on right now all started with this beauty. A failed solder joint which had been buried in adhesive heat shrink...
The wiring on this boat was some of the worst I have seen and the orders from the owner:
"I would like all unnecessary wiring removed, and what is necessary neatened up." Sounds easy enough... NOT!!
This was 67.5 hours of "
unnecessary wiring removal" on a 34' Down East "Lobster Yacht"...... Other than a couple of v-belts and two cracked & brittle PVC hoses, the
unnecessary wiring filled an entire trash can and weighed more than 70 pounds....
Pride of workmanship...? Non-existent... When ever something new was added the old wires were just left in-place. I found 5 broken solder joints, & 3 crimps that literally fell apart when you touched them (made with pliers). There were perhaps 15 connections made by twisting wires together, most all of which would not pass current, likely why the circuit was bypassed to begin with. What was there was not even wired correctly. For example when you turned the search light to Port it went down. When you turned it to Starboard it went to Port. The NMEA 2K system was fraught with issues. For starters the N2K was powered by autopilot breaker so in order to use satellite weather, the GPS antenna, the bridge plotter, the sounder, the network expander, lower helm plotter and the instruments you had to have the AP on. The system only had one power drop, consisting of wires twisted together, so the GHC10's and other instruments would often drop out.
The owner got a "
good deal" on this boat yet it has already needed a complete re-power at 33k, and a LOT of the wiring has been re-done. The
good deal is long behind him and the new term is "
money pit".....
I won't even go into the 400A 12V bow thruster fed by a single G-24 starting battery that was being charged via a diode isolator, 28' away, using 10GA wire. He had about 10 seconds before the thruster would peter out. The owner has been slowly fixing the boat for 4 years. I do a bit each year to the electrical system and one more year (next winter) should have it in "
decent shape" not perfect, but
decent..
It would have cost considerably less to rip 100% of it out the first year and entirely start from scratch, as I suggested he do, but he chose to do the "patch up".
Be careful with those "
good deals"....

Today:
Install & wire an inverter
Finish wiring a high performance alternator & programming the regulator
Install a starting battery
Install & wire a 12V outlet on the bridge
Install & wire a set of saloon speakers
Off to work...
