Wire Chafe Again
Anyone interested in hand-steering that last 650 nautical miles...??? Protect your wires from chafe or you may just be hand steering for the next few days on that long off shore passage........!
These wires passed through a locker and the hanging items frequently moved under sail, pulled on the wire and chafed it against the sharp fiberglass. After unloading piles of stuff from this locker, think "crammed with clowns in a Volkswagen", I discovered this chafe and could replicate it by moving stuff in the locker.. In its installed position the chafe could barely be seen but when the wires were pulled you could easily see it.
I Know It May Not Be Sinking In.....
Remember boats are just like houses. This guy on the internet says to solder the solid copper wire then use wire nuts and then there's no need for wire ties, because BOATS DON'T VIBRATE......... (WINK!)
Over Current Protection Is Not Optional
Just a few minutes before this boat erupted into flames a number of 8 year old junior sailing program kids were on-board. The wiring on this boat had no over current protection.. Scary FAIL.....
A Starting Battery & No Fusing.....
This boat is used as a chase boat in a junior sailing program... Over current protection is NOT optional!!!
How Many Times Do I Have To Explain It...
How many times do I have to say it. There's no need for over current protection, IF YOU WANT TO BURN YOUR BOAT DOWN!!!!!!
This was a DIY bilge pump install with NO FUSE!!!!!!!!!!
The wire got so hot it literally turned from stranded copper to solid copper...... It luckily fused itself, & melted in two, before the boat caught on fire..
The wire is NOT supposed to be your FUSE!!!
What's In A Picture..??
****CLICK ON THIS IMAGE TO MAKE IT LARGER****
Just from this one single picture we have:
#1 A dead short circuit that caused a small gauge wire to physically melt and almost catch this boat on fire. This melt down was cause by NO OVER CURRENT PROTECTION.
#2 Improper lug stacking in multiple locations.
#3 Extremely poorly executed terminations.
#4 Improperly wired main AC breaker. This is only breaking the HOT/BLACK wire in the 120V system. I NEEDS to break both HOT/BLACK and WHITE/NEUTRAL!!!
#5 Improperly supported/non-supported terminal strip hanging by what looks to be a 16GA black wire.
#6 Unused over current protection which has been bypassed.
#7 Complete and utter lack of over current protection where the wire gauges drop from 4GA to 14 - 16GA. Over current protection is NOT optional when wires change size. Most often the fuse or OCP for the larger wire is too large for the smaller wire to handle...
#8 A 4GA wire disappearing into a mess of electrical tape. What surprises is this hiding?
#9 No AC/DC isolation, in the form of a cover for the AC wiring/terminals, on the back of the panel.
#10 Improper use of color coding. Black DC wires connected to positive DC terminals and not marked as positive.
#11 Complete lack of adequate wire support. This may be what led to the dead short somewhere else that caused this melt down.

Boat Fire Narrowly Averted !!

Three words - OVER CURRENT PROTECTION

Leaks Can Be Dangerous
When you notice water dripping out of a 120V outlet, ADDRESS THE ISSUE PLEASE !!!
C'mon really........?? Why builders go to this level of CHEAP is beyond comprehension.... Epic FAIL...
The infamous Universal/Westerbeke Trailer Conenctor
Universal & Westerbeke engines ship with these "trailer connectors" in the engine wiring harness & when used to power only insutruments they can work ok...
The problem is that some early Universal engines even ran the full alternator output through the orange and red wires... These connectors can be very DANGEROUS if that is the case...!!! Connector FAIL!
Packing Gland Hose FAIL
Not only was this hose ready to fail at any moment, and sink this boat, the second hose clamp is doing NOTHING but clamping AIR.
This sort of nonsense can actually force the hose off the shaft log and make it less safe not more safe.. Please, please, please pay attention to WHAT you are actually clamping!!
