I have had 2 batteries, one the dealer replaced when he sold me the car, the second I bought because it would not hold a load. I have tested for battery drain, I do show some drainage, removed radio fuse, the same, removed connections to my radar and rear headrest DVD, sane drain, removed every fuse under the hood same drain, the battery will only last 5 days without a charge. So every time I leave the car over 3 days I keep a trickle charger, or remove the ground if I leave at the airport.
I was wondering what is the siren noise in the rear of the car when the battery is low and needs a charge? Hook up the charger and a siren goes on at the right rear, sort of like a break in alarm, it also looks like the battery only lets itself get to a point of drainage where it stops draining the battery. If I hook up a charger it takes an hr and the car is good to go for daily driving. As long as the car is driven everyday or before3-5 days are up it starts fine. Any ideas. Seems to be a problem with every SRX I wanted to test drive, they always had to re charge the battery before I could drive it (5 cars tested).
You sub woofer is back there, is it possible that the amp is powering it all the time for some reason?
You installed a bunch of aftermarket stuff in a very short time so it could be anything, the way the car talks to other parts of the car means that two unrelated things could cause issues that don't make any sense. Not saying its an aftermarket item but im just saying.
I will have to pull the fuses in the back, but what a hassel to remove trim panels! How about that siren going off when charging the battery, is that some kind of alarm that goes off when the battery is at a level is going to be to weak?
AHHH SOOOO ok. So next time I run into this I should pull the radio fuse, would that be enough to stop power to the sub wof in the back. The sound is coming from the right rear panel, the sound lasts for about 5 mins before going off on its own when charging
I had a Power Capacitor wired in with a Sub woofer in another car. Whenever there was loss of power from the battery, the Cap would alarm on 'low voltage' until in either a) ran out of power b) was re-charged from the cars 12v supply
Do you have some sort of Cap or auxiliary power to your amplifier / sub?
