Ok, so who besides me with newer model Sea Rays have these installed over the old fashioned battery switches? I ask because I am not so sure my system is operating correctly.
My boat (230 W SLX) has 4 batteries installed. One for the bow thruster, one for the stern thruster, one for the engine, and one for the house. There are ACRs that are supposed to keep them all charged via the alternator when engine is running. I noticed that when out surfing and having lights, stereo, etc on that I would get a message on the display that said "low voltage - reduce battery loads or run engine above 1,000 rpm". I did that while getting back to the dock but the message never went away and the gauge on display did show the house battery right at half.
So last night at the dock I idled the engine around 1500 RPM and used a meter on each battery. The only one that is getting a charge is the engine battery. At what point does this relay "close" and start charging all the batteries? Does the battery have to get low to a certain point before it opens up?
