netjordan Posted March 12, 2016 Share Posted March 12, 2016 Hello I'm in the process of installing a Galaxy G2-20 but have run into a bit of an issue, Essentially connecting the battery seems to 'break' something. With AC connected, and battery connected the SAB power and Keypad LCD (and Keypad Backlight) turns off. Keypad LED Remains on and AUX Power Remains on. Removal of the battery returns power output & keypad to expected functionality. I've checked the polarity & voltage at various points and all seems good. Anyone got any ideas or seen this before?

norman Posted March 12, 2016 Share Posted March 12, 2016 Is the battery charged? What type and Ah is it? Nothing is foolproof to a sufficiently talented fool.

netjordan Posted March 12, 2016 Author Share Posted March 12, 2016 Is the battery charged? What type and Ah is it? It's a 7Ah Lead Acid battery. Voltage on the battery is about 12.5V, when connected to the panel the 12v outputs on the panel are around 2.5V Link to comment https://www.thesecurityinstaller.co.uk/community/topic/39873-galaxy-g2-20-battery-problem/#findComment-442701 Share on other sites More sharing options...
Lwillis Posted March 12, 2016 Share Posted March 12, 2016 Is the battery charged correctly. Seems few batteries with reversed polarity on them.

netjordan Posted March 12, 2016 Author Share Posted March 12, 2016 Is the battery charged correctly. Seems few batteries with reversed polarity on them. Just checked polarity and voltage of the battery with a multimeter - 12.9V and polarity correct. I've tried three different batteries, with the latest one being brand new.

norman Posted March 12, 2016 Share Posted March 12, 2016 Where did you source the panel from? Nothing is foolproof to a sufficiently talented fool.

netjordan Posted March 12, 2016 Author Share Posted March 12, 2016 Where did you source the panel from? It was from eBay - brand new. Came with all the packaging, manuals, screws and resistors etc. Link to comment https://www.thesecurityinstaller.co.uk/community/topic/39873-galaxy-g2-20-battery-problem/#findComment-442706 Share on other sites More sharing options...
norman Posted March 12, 2016 Share Posted March 12, 2016 Remove everything except the rkp and try again with the battery. Nothing is foolproof to a sufficiently talented fool.

Nova-Security Posted March 12, 2016 Share Posted March 12, 2016 battery could be knackered, seen batteries with 12v on meter but current reading less than 1amp, cells had gone low resistance, check battery resistance with meter. www.nova-security.co.uk www.nsiapproved.co.uk No PMs please unless i know you or you are using this board with your proper name.
