Folks
I really need some help to try and even work out where to look! Cinnamon - our delightful Targa 33 - still knows how to put up a fight during this gorgeous weather!
Here's the symptoms...
3 batteries - 1 starboard, isolated to start the s'bd engine; 2 port batteries to start the port engine and run the domestic electrics.
Boat has been on shore power all week. Know that's working because the electic sockets that are attached to the shore power are all live and kicking.
Come to start up - s'bd engine won't start - no battery. Only when I moved the terminals over onto one of the port batteries would it turn over. Once s'bd had fired up, put the terminals back onto the "original" batteries and fired up the port.
Now - voltage meters on the dashboard indicate just over 13V on the s/board and never more than 12V on the port.
40-odd minute cruise later - stop to invesigate pubs / bird life etc and pose! All domestic electrics happy. Fridge, Stereo... everything cool.
When we come to depart, s/board engine turns over really slowly before eventually firing. port engine? lovely - turns over reassuringly quick before firing up happily.
Port voltage still reads 12V, s/b 13.2... but it's the starboard that appears to be in trouble!
Now - en route - we lose our domestic electrics. Except the fridge! No (domestic) water pump, no stereo, no depth/speed, no lights. But we still get to keep our fridge! Ok - turn the fridge off - nope - we don't get any of our electics back.
Dashboard still happily registering 12/13.2 port/s'board and all dashboard guages still happily working.
All 3 batteries are new within the last month. OK - everything was pointing to the s/bd battery - except that the domestic electrics run off the port, who's (dashboard) voltage never read more than 12V.
On return to harbour, we plug in to the shore power. Yep - the little light on the hoover that's plugged into a shore power plug is on. Kettle works etc. Fridge still works (off the domestic electrics remember!) Plugging and unplugging the shore power makes no difference to either dashboard voltage guage.
Summary - s'bd battery is a month old but can't start the engine even after being on shore power for a week, but reads 13.2V when the engine is running; port batteries - also a month old and green dots in the window tell me they're holding full charge - can start the engine happily, but can't deliver consistent domestic electrics and the voltage reads 12V when the engines are running...
Anyone got any idea what the hell is going on? Battery charger? Battery? Which one/two/three? Boat?!
All the best
