Arrived at our marina this morning to step our mast with a new Harken furler. Our battery was too low to crank the engine (2nd time on this battery)so I got a starter battery from the marina. Cranked the engine - no problems through the mast stepping process and return to our slip.
Decided to buy a new battery. After tuning the mast, and setting up the boom and main, I installed the new battery, connecting it as always before. We had an immediate low volume ringing alarm sound. Not the one that sounds when I turn the engine key, before engaging the starter. Did start the engine which was normal. Engine noise made it impossible to tell if the ringing/alarm was still there. After shut dowon, it was there.
Tried disconnecting all wires on the battery. (Radio and depth guage are direct connected.) Sound persists with only the two main power connectors. Sound seems to be coming from the starboard cockpit Lazarette behind where the standard Yanmar control panel is installed.
Configuration:
1GM10 Yanmar new around 2012
Single battery for starting and load on the hook.
Depth guage
Horizon Intrepid radio with antenna at top of mast
12 volt outlet for the autopilot, but nothing attached.
No other sensors or alarms that I know of. (We have sailed our boat around 8,000 nm over 24 seasons on Lakes Erie, St. Clair, and Huron.)
Cabin and navigation lights.
110 volt shore power system for lights, charging electronics, and microwave. Not connected to the 12 volt system.
Marina staff has gone home. Pretty sure they won’t be in tomorrow. Don’t know any local marine electricians. No referral from the local West Marine store.
Any ideas for further trouble shooting, or possible sources? On a 47 year old boat with an unknown number of prior owners, there could be stuff we don’t know about on the boat.
Thanks in advance,
David
