Thanks for that -
It seems I have a bigger problem. The New battery i had installed has drained and it is not charging. Having had a closer look one of the resistor's in the Gardtec 300 series control panel has blown. However, If I take the fuse on the circuit board out, the Alarm bell sounds.
I guess what I need is a Gardtec 300 series control panel, to replace the current one.
any further advise / help would be appreciated as I am totaly stuck on this as afer as DIY is concerned
