Battery switches. On or off?

[bajturner]

The battery switch dictates which battery(s) power is pulled from, not which one(s) will be charged.

This is true regarding the converter, as the outputs bypass the battery switches. This is not true regarding the alternators (at least for the boats I have owned, and other Sea Rays of similar era I have seen), as the alternator outputs do pass through the switches (and why you should never turn them to off with the engines running).

Excellent point and reminder to not turn the switch to off while running. I have read to not even switch between positions as even this puts the switch in a momentary "off" as you pass through one position to the next.

I never touch the switch while running. Can't think of a reason you would need to.

Hmm, great info. With 2 toddlers who love every little nook, hatch, latch, and button...we have looked into a locking mechanism for the battery switch door.

Not true. Note the order of the switch labels:



2 connects to 1 before disconnecting from 2.

I'm not sure of the positions on my switch. However, are you sure that the connection stays solid when passing (for example) from 2 to All? I would have thought that for a brief second, there would be a dead spot between any two positions.

Believe me, I'm not doubting your answer. I'm just asking in order to learn from you guys.

Thanks.
