When I would turn on batteries I would hear a click and I would have power before, and with the batteries turned off I would have no power to anything. Now with batteries turned off and when I plug in...
Huh? Do you have an INverter your trying to use to power some 120VAC appliances. Or do you have a CONverter your trying to charge the battery with and use 12VDC lights etc? Either way, dead battery is first thing to check.
