I agree. My electrical systems seem to get screwed up easily too. I test my FF and bait tank before each fishing trip.

A good flush of fresh water and scrupulous cleaning when I get home. I clean the connectors with contact spray. I blast them dry with a pressurized air bottle, then a good coat of dialectic grease.

I replaced all of my wire connectors with heat-shrink connectors. In the past I've filled the connectors with silicone caulking before applying the heat gun. The silicone squeezes out as they shrink and the result has been good.

Lately I've been covering all shrink connectors with brush on "Liquid Electrical Tape" from Home Depot. Same for the push on battery connectors - pushed in place then painted with Liquid Electrical Tape to seal them.

IMHO, electrical systems pretty much need regular cleaning and maintenance. Otherwise I'll be wasting time fiddling when I should be fishing.
