We bought a used boat
with two solar
controllers and what i think is another thing connected to a wind
gen. While troubleshooting the electrical system
trying to track down what's draining my batteries, I disconnected all the positive leads from the battery
bank. all the controllers went blank. I reconnected the positive leads, but the controllers are still blank. While it was all disconnected, I put a meter on what should be the output of the MPPTs but there was no voltage.
Did I screw them up by disconnecting them from the batteries? I haven't seen the manuals
for these, although they may be on board.
