At least last year, three times out and the stereo battery was dead. If they are isolated while underway, it's just getting drained, and only charged when at idle, which isn't a whole lot of time. Since then I've had it on a charger after a day on the water.
When I have looked at the ACR, I have a solid steady green LED. I assume this mean the batteries are combined??
So, I am curious as well, is the SI circuit really needed?? I don't particulalry want to fish a wire (or pull the floor up) for something that isn't necessarily needed. I could however try to find that relay under that dash...
