For the first time, I have a boat with dual batteries and a Perko switch on my 2017 RSB. Can I switch the Perko while underway?
I did some reading and it made my head hurt. My understanding is boats rigged in the last few years should be rigged to "make before break" so I should be OK. But if it was rigged to "break before make," you can fry some electronics like the alternator. ("Make" the connection to the newly selected battery before breaking the connection to the previously selected battery.) I do understand never to switch the Perko to off with the engine running. But I think going from battery 1 to 1+2 to battery 2 should be OK.
