When I purchased the boat a few months ago everything worked well. Now, the stereo won't stay on long enough for a cd to start. The fan runs at 1/3 original speed. I have replaced the fuses.
I have two batteries, 3 solar panels.
It doesn't look like shore power does anything besides run ac power. It's not charging my batteries. I am guessing the solar panels aren't working properly as well but do not know how to check them out.
Do you have a voltmeter? If so, what reading is it giving?
How are the solar panels wired to the batteries? Is there a charge controller?
