all digital radios have a constant power wire to keep the memory once the radio is switched off this should only draw a very small amount of current almost unreadable with an amp-meter well below one amp but anything over one amp or even close to it would be enough to drain your battery
you could have a faulty radio or else its a very bad make of radio
if you bought it new take it back and tell them your problem
my 1992 golf does this... it was due to the new amp and stereo :) fit a spare in the boot solved my problem
There is a circuit live somewhere.
While the car is running the alternator should be recharging the battery faster than stereo can drain it. I suspect you either have a problem with the alternator or its time to get your battery replaced. Until you get it fixed, if you don't turn on the radio, it wont drain your battery :) If it is a high power model, it needs to be wired directly to the battery.
something is draining the battery I have put a new battery and a new starter ans also a new alternator and something is still pulling it down can you help me?
Then either something is on draining the battery or the battery has a dead cell draining all the rest and must be replaced.
If the battery is brand-new and I would suspect either the alternator is defective or you have a lightbulb somewhere on the vehicle that is pulling power from the battery. It can also be a relay that is stuck.
What else is in the system? Was the battery charged and tested when the new alternator was put in? A new alternator can blow out if it is trying to charge a "Bad" battery. Was it a new alternator that was tested by a shop? It is possible it is a factory defect. If it was done by a shop I would take it back to the shop. It is also possible that there is a wire off or grounding that is draining the system. Have you installed a stereo amplifier? Some amplifiers draw more current than the car can provide.
A short will not drain the battery it will blow a fuse. It may be the battery has a dead cell, or some light is on draining the battery. It can also be a stuck relay.
one is for the stereo for memory, on is for the cars computer, and one is probily for the interior lights tha come on when you open the car door.
To prevent the batteries from draining during shipping and shelf time at the store.
Something is on draining your battery overnight. Any light or any relay. It can also be your battery has a dead cell draining it overnight.
Something is usually on that you don't know about like an alarm could be draining the battery. However, If its not starting you should check the starter though. It will make you think the battery is bone dead.
