All I wanted to do, while visiting the boat today, was tune the rigging, install the boom and mainsail, recharge the batteries with shore power, purge the antifreeze and refill the tank with fresh water...as well as a bit of deck and salon cleanup. I plugged the ship to shore power cable into the dock pedestal then into the boat inlet, and low and behold...nothing on board. No AC power. Batteries were already a bit low, but the boat was successfully motored to it’s slip so a bit in reserve on the DC side.
My AC/DC panel looks like this from front...
So out comes the multimeter and I test everything from the dock pedestal back to the cabinet. 120V AC all the way back to the cabinet. Pedestal’s good, extension cord good, 120V AC into cabinet. Even removed the male end of the boat plug from the port sidewall, and probed the leads coming into the boat. All good, voltage everywhere.
So I shut off the power at the dock pedestal, and went back to rudiments. Probing between the terminals of the main AC breaker...switch on 2.1 ohms, switch off open, breaker switch good.
Then I noticed a device, directly below the main switch on the panel, which had the “hot”AC lead connected from the exterior input wires, with no toggle, no switch, to a buss bar of the remaining switches ...and a distinctive gap on the front panel.
What is this? Can I get another new one? Labeled as unknown component in the image below.
This component reads open in power on or off. Infinite resistance, even after tapped with a screwdriver. No reset options apparent. What to do?
On another favorable note I met Michael Brazil @Brazil today at Cayuga Lake. All I can say is Hunter Sailboats rule...with the exception of the electrical matrix and PO modifications that are stupid. I’m one of those inheritants.
