Title: Two main battery switches on a Bavaria 44
Post by: ancanc on October 03 2023, 19:11
Hi,
I have a Bavaria 44 / 2003 with two main battery switches underneath the chart table - unfortunately the wiring diagram shows only one.
The second one (closer to the captain's seat) controls almost everything I use, have no idea what the first one is for, anyone found it out eventually?
Thanks
Andras

Windlass? Bow thruster? Inverter?

Bow thruster has a direct connection through a fuse, I installed the inverter, it has its own switch. Windlass - could be, going to check it tomorrow.. Thanks

On my vessel, one is for the engine starter battery and one is for the house batteries.
I also have a third switch for linking the batteries to start the engine off the house batteries.

Thanks, this is what I was thinking the whole time too. Unfortunately the "house battery" switch went wrong and I could not start the engine - until I found out that pushing the switch key helps, I was lucky that I was not alone.. Switched off the first switch (the motor switch?) but everything is still working with the "house battery" switched on. I am the second owner, so maybe someone made some "undocumented" changes or connections, II will have to follow the 95sqmm wire coming off the first switch to find it out I think.
I replaced the original Quick QIS15N with max. 150A permanent load with an Osculati Heavy Duty MKII 14.385.10. (280A max permanent load)  The new one needs a larger hole (28mm instead of 25mm) but fortunately the original hole was big enough.
