Electrical question regarding batteries. I run three stereo batteries and one starting bat. The last time I had the boat out I started getting an over volt on one of the banks according to the touchscreen. Not sure which bank it was but one bank was showing 13 V and the other one would Get as high as 15 or 16. My first thought was the alternator, but doesn't make sense if it's only happening on one bank. Are there two different voltage regulators?
