You could try EOLR's (end of the line resistors) on all the zones... usually all of the zones on the panels i've installed needs a 1000 Ohm resistor attached to it, or you can simply replace the 12 volt battery. Take off the 2 leads from the battery, remember what one goes on the red lead, and what goes on the black, and just re attach it to the new battery. Let me know how that works out for you... Marlonsaunt@yahoo.com email me if you get it working right.
