    Default Major Screw Up - Cut Wires

    UGHHH, even though I had tried to insure nothing was behind I screwed up and cut through a bunch of wires. Anybody have any great info for the fix?20180922_113129.jpg

    I then cut the hole much larger for better access today and in the future. It will either get just an access plate or maybe a hinged door.20180922_143812.jpg
    This is the original rot and my marked lines for making the cuts.20180922_112018.jpg

    Solder and heat shrink tubing
    Been there, done that...

    Was that penel installed with devil sperm (5200)?

    At least none were "hot" so I didn't fry anything. Also, in opening this all up I see that I'm not happy with the way additional wiring and the tubing for the AC compressor had been run. I think that has been causing some issues below with water intrusion.

    No 5200 but some type of glue was used. Same thing used on the panels for the seat base sides on the flybridge. Sticks a little but does not come apart too bad.

    I think the wire cutting incident is a perfect opportunity for some rewiring. Some of those wires do not look like they belong anywhere near a boat.

    In agreement with Chris, remove and replace non compliant wiring.

    Just rewire. Better off.

    There are two kinds of boaters: those who have run aground, and those who lie about it.

    Yes. And then, when something loses it's Lucas Magic Smoke™️, you'll know what's under there.

    Agreed with those above, I believe I see Romex and also lamp cord in there !

    Another "please rewire" vote. 1) (as said) you'll know what's under there & 2) it'll be far safer with real marine wire (which is what you'll use, right? )

    My older boats Goblin and Marmalade had chaotic wiring because they were wired by evolution - something added here, replaced but wires not removed there - and despite the beliefs of some anti-science types, evolution is not smart. Not dumb either. Just whatever. And after you've removed sixty pounds if wires to nowhere, you'll be right there as well - whatever.

    It will actually be less work to rewire. Really.

    Ditto....I'm on my third total rewire and I don't miss an inch of the C$@* I pulled out

    This?

    http://www3.telus.net/bc_triumph_registry/smoke.htm
    Here is presented for your perusal one Lucas Replacement Wiring Harness Smoke kit, P/N 530433, along with the very rare Churchill Tool 18G548BS adapter tube and metering valve. These kits were supplied surreptitiously to Lucas factory technicians as a trouble-shooting and repair aid for the rectification of chronic electrical problems on a plethora of British cars. The smoke is metered, through the fuse box, into the circuit which has released it's original smoke until the leak is located and repaired. The affected circuit is then rectified and the replacement smoke re-introduced. An advantage over the cheap repro smoke kits currently available is the exceptionally rare Churchill metering valve and fuse box adapter. It enables the intrepid and highly skilled British Car Technician to meter the precise amount of genuine Lucas smoke required by the circuit.

    How old is the boat? I’ve found that the amps delivered and the gauge of the wires in old boats are a lot like wiring in old houses. Who will ever need more than 60 amps of service in a house? This gauge of wire is more than sufficient to provide that. I once had a 24’ T-top fishing boat built it 1996, bought used. After a while of use I began noticing intermittent electrical problems ranging from nav lights, to bilge pump, to speakers. Since I wanted to add more circuits for additional electronics I decided to solve all the problems at once. I was horrified when I started digging into the situation.

    The fuse panels and wiring connectors were were all corroded because of being non-marine grade automotive connectors, the wiring was corroded, romex and 18-20 gauge big box store wire. It was amazing that any of it worked, not to mention I wanted to deliver additional amps for more equipment.

    To fix the problem would require a complete rewiring, which would require bascailly gutting the interior to the boat to get to the races. I judged the expense not worthwhile given that I only paid $9k for the boat, 150 hp merc and trailer. I used the boat a couple of seasons, close in to shore then sold it for ~6k. Lesson learned and I moved on.

    Cutting those wires may be a message from God. :-)

    In the spirit of "Do as I say not as I do." I recommend rewiring. I would probably patch and only replace the most egregious and readily accessible wires.

    Some of the wires look like they are fairly heavy gage. I would consider these: (https://www.alliedelec.com/m/d/3c533...3e39987246.pdf https://www.alliedelec.com/te-connec...yABEgLko_D_BwE ) or these: https://www.cableorganizer.com/gardn...t-splice-kits/ Home Despot has them too. For the smaller wires, there was a thread recently about solder sleeves for smaller wires. https://www.alliedelec.com/te-connec...SABEgKYFPD_BwE (not for solid wire?)

    If you have enough slack in the wires, the Western Union splice works for solid wires: https://makezine.com/2012/02/28/how-...asa-standards/ The link to the NASA standard is out of date. The current link is here: https://standards.nasa.gov/standard/nasa/nasa-std-87394 Page 71
    "13.3.2 Solid conductors shall be assembled in contacts by soldering, and cleaned and inspected in accordance with the latest revision of IPC J-STD-001FS."
    The dual wall with adhesive heat shrink tubing is more waterproof. https://www.amazon.com/dp/B0771K1Z7Q...detail_1?psc=1

    [QUOTE=MN Dave;5682402] I would probably patch and only replace the most egregious and readily accessible wires.

    This is the what I chose to do. I replaced the fuse box, connectors and accessible relays with marine grade products and shined up the wires the best I could. I didn’t add any more load to the system. In fact I removed wires that didn’t seem to serve any purpose and simplified the wiring to the panel. It served the purpose for a couple more seasons.

    After reading your other post about this being an old GB in need to renovation, I Change my opinion on what is needed to be done about the wiriing to Mama Mia!

    Taking a chance on a sketchy electrical system on a small fishing boat close in to shore is one thing, taking a chance on the electrical system on an off shore boat is another. During the renovation I’d add renovate the electrical system to the list.
    Seaworthiness and safety come first. Unless you are planning to use the boat as a floating condo, which lots of people do.

    I'd say it's as important then as any. Most marina fires in this area are caused by overloaded circuits in "condo" boats...usually heaters
