Hi. I have changed the 2 accus (batteries) of the alarm siren. Now the alarm-LED is on during driving. Master-switch was off while siren was out. What's wrong? How can I find out the reason for LED on? Best Regards Gerhard
Did you change the batteries because the alarm LED was constantly on? If it's still on, maybe the new batteries were not soldered in correctly. I would recheck that. Did you see any leaking electrolyte damage on the circuit board?
One of three things. The batteries in the Alarm aren't working, the circuit board is toast, the connection is bad at the plug into the unit.
