Boat is an '84
sloop with a 13 hp
yanmar and the standard 2 bank, house/start
battery system.
Batteries are less than a year old. Previous work/installations seem to have been competent and to ABYC specs according to the
survey. I've had the
boat a year.
I'm in the habit of leaving one light switch in the on position when I turn off the
battery selector switch when leaving the boat. That way, I reach in, turn the selector switch and I get light to go down the stairs without needing to find the breaker in the dark. In the past this has always worked fine.
This is no longer works fine. If I turn off the battery switch with the
cabin and or
cockpit light breaker panel switch on, I still get dimly glowing lights. It was really late with a dog that needed
food and walking so I turned off everything at the panel and went home.
Switch is the regular old Perko 1,2,both, off type with no auto field disconnect. Finding missing voltage seems intuitive. Figuring out why voltage is going around a supposedly disconnected switch is less so. Besides tighten/clean connections, where do I start? How do I test the switch? Can I use the "com" terminal to test for infinite resistance in the off position or do I have to go terminal one or two to a battery ground? I'd bet $50 bucks on a new switch but I read that they rarely go bad and if that doesn't fix it, I'm still right where I am now at a loss on where to begin and hoping for your
tender mercies.
Any and all tips appreciated,
Kurt
