oday 34 panel settings

[Swaney]

I am new to my 34 oday. Could someone please explain what the panel selection difference between-All 1 and off are. I use the all position when sailing and of course off turns he panel off but position 1 I think is my starting battery.

Congrats on the new boat. It sounds like your asking about your battery selection switch. The 1 position is powering from one battery. All would be all batteries and off is no power.

Isn't there also a 2 position? Best to only select one battery (or bank) to keep the other one in reserve to start the engine. Selecting All almost never makes sense.

If it is a 1-2-both-off switch, read this article, explains a lot as do the rest of the articles on the site.

Fundamental to the value of having two batteries is that they both be good. Load testing each would not be a bad idea, replacing if marginal.
