My Solar panels won't charge the battery
Question:I have a 2001 Fleetwood Flair with rooftop solar panels connected to the engine battery which has worked as long as we have had the Moterhome. Now my engine battery is dead and there is no voltage present on the leads at the battery location. The battery is fine, I hooked up my external battery charge and the battery recovered. I am an EE so electrical problems are not a problem to me but I don't know if there is a controller somewhere between my solar panels and battery so I don't know where to start. Help!

Robbie: Simple test for you...
Follow the wires from the panels into your RV and where they connect. Disconnect the wires. Using a meter, the output from the panels should be around 26 to 29 volts on a sunny day. If this is what you have, check the output side of the regulator should be 13.1 to 14.2
Last check the connection at your battery disconnected and connected. Be sure you're not trying to charge a battery with a dead cell.
