Clifford concept 300 siren battery ?
 

hey does anyone know when the battery is supposed 2 charge , is it when engine on running or when alarm activated, just mine is reading dead and its new ! and been on car 4 a week so need 2 c if its charging

check the alarm brain.. some of the clifford range have a fuse in the lead that the siren plugs into. It's usually a 1 or 2 amp. It may be blown which would stop the siren from charging..

well done some more testing and theres a good current coming into siren wen engine running, and now the battery has a chargeof like 9.5v but still only chirps about 5% of time, spoke 2 clifford and they think siren 2, was gonna borrow someone elses but on mine it has a red/black/green and yellow caables off to the brain, but theirs doesnt have the green ! i thought all G4 and G5 ;s were same ?
