tried to install this panel but it keeps blowing the 1.6a battery fuse (i tried 3 times but it blew each time) .I bench tested the panel using mains only and was able to successfully set up and test as per the installation instruction. The Bell, strobe PIRs and LEDs worked fine but each time i connected the battery it blew the fuse. I have checked the wiring instructions and cannot see any obvious reason for the problem.Your assistance will be greatly appreciated

id suggest your battery is either gone, charged wrong polarity or leads in the wrong positions

Don't forget the obvious short circuit somewhere
