Gday
I own an 1993 Falcon EB. After putting in a new car stereo the battery drained flat when I left the car unused for a couple of days. After pulling out the stereo I then checked the fuses to see where else it may be draining. As I was not sure it was the stereo. Checked the battery drain on the fuse box and the following is how it looks. ACCY RLY 140mAmps CRT LP 700mAmps Wipers 13mAmps I assume the ACCY RLY is the accessories relay so that makes sense with the car stereo but I no idea what the CRT LP is and why its pulling so much power with the car off. Any ideas? Cheers Alex |

the crt is for your interior lamps and smart lock, if you had the door open when you checked it that would explain the current draw. what did you wire your stereo up too? are you running amps? if so did you wire up the power lead dirrectly to the battery and the remote lead to an ignition source? if you wired up the remote terminal to constant power than the amp/amps will be running all the time hence draining your battery!

Thanks Flash,
I think I wired it up wrong. The last person cut all the wires and there was no loom plug, also there are no labels on the car stereo as to what is ignition and what is constant. Any way I can check the stereo ( I know how to check the car end ). I will double check the CRT LP with the door closed. Cheers |

from the radio; from memory
the yellow wire is constant i.e. battery power the red is ignition i.e. when you turn the key black is earth blue is for power arial (can also be used to switch on an amp in some models) orange is power out (also used to switch on an amp in some models) then with the speaker wires as they can be different colours with some car radios just put your balance say all the way to the left and all the way to the front then just search through the cars speaker wires till you find the corosponding speaker.

cause all capacitor drain your battery according to a lot of "KNOW IT ALLS",dont' stress,the only way it can be your cap is if it is stuffed or you wired it up wrong.i had same prob in my eb and i thought cap or amp at first but it turned out to be my constant 12v from car was wired into my acc12v at the deck and vice verca,so maybe check yours for that!! cheers

If you have the constant and ignition wires the wrong way around then your deck will not retain any settings (i.e radio presets) or switch on automatically... does this happen ?

Hi
Thanks everyone for all your help so far. Not sure if I wired the radio up wrong, I have pulled the radio out. Is there a way of checking the accessory relay? There is a current running across the fuse when the key is out, about 150mAmps. AND The wipers and interior fan work when the key is out?!?!? WHY? This is driving me a little nuts lol. Also the voltage across the battery is 13.4V when idling and 12.8V idling with the lights on. I reckon that means the alternator is on the fritz but a mate told me it is because the battery is not fully charged yet. What do you think? Thanks again, Alex |

Thanks again, Alex could be alternator, the tensioner might need tightening a little bit because the belt is slipping, or the alternator is on its way out. Charge should be constant, maybe a bit of fluctuation when flicking things on and off, but usually constant. phong =P~
