flat battery, alarm sounding


Recommended Posts

2005 sc430.

My passenger door was, by mistakem, left not fully closed overnight. Saw it ajar next morning. Closed it fully, and tried to lock the car with wouldnt lock. I locked the car on driver side with key. Minutes later I heard a feint alarm sound (not from main horns) coming from the boot. I inserted key in ign and turned on...hoping the feint alarm would stop, it did, but started again 10-15 sec later. All the dash lights were blank, the Battery was flat. Ive disconected the LIVE off the Battery, and connected my Battery charger.

1hr later, when Battery had some charge, I reconnected the live on the Battery. The alarm began to sound...loudly. I turned ign on, and started the engine. The alarm cotinued to sound for another 5-10sec, then turned off thankfully.

Hope this is usefull info to somebody.
