I agree with Delmarry as well, but will take it a bit further. The electrical
connections are terrible. 1) There should be proper heat shrink on the larger cables
to prevent wicking. Not red electrical
tape. There is already a lot of signs of corrosion
on the surface terminals. I would just assume there is wicking occuring there and would replace the connectors and use heat shrink.
2) The three spade connectors are begging for corrosion
and poor contact. Use good heat shrink spade connectors. 3) Lose the cheap
white splice and again use a proper heat shrinkable butt splice. In fact I'd get rid of that type of fuse and get a good marine
grade fuse holder that protects the fuse connectors from the corrosion seen seeping into the left end of the fuse holder pictured. Corrosion breeds resistance, resistance breeds hot spots and failure. 4) Never take for granted chafing of unsecured wires. The two red cables
on the left look like they are leaving a bulk head
and are not secured and the edges of the bulk head
look like a great place for chafing.
There are places to certainly save money
on any boat, but proper electrical connectors are not one of them. Not only will your boats electrical system
be safer the connections will last a lot longer and give a lot more trouble free service
that adds up to be far more valuble than saving a few dollars on cheapo connectors. Windlass
relays are designed to be water
resistant because this is one spot that is very common for salt water
to track back on the cables from exposed windlasses. The cheap
connectors make it a weak link.
