My car battery went flat,now my car radio?
Answers:
sounds like you have lost the code for the radio , you can get this from the dealership but you will have to take with you proof of ownership and some photo i.d . if it is a ford radio email me and i can send you the code for your radio and give you instruction`s on how to enter the code !
look in your car paper work there should be a code number for the radio , put it in right , if you do not contact the first place the car was sold from they will have it
your battery doesnt have enuff power or charge to support your radio. you must check your alternator if thats not charging the battery it could kill your stereo.
what tpye of radio is it? some have sensors in them so when they are stolen they dont work. check with the car and radio manual.
have you connected the battery the right way round and is it fully charged? maybe you connected the wires in the wrong order and blew the fuse in the radio.
your radio requires a small amount of power 24hrs a day,
if your battery had gone flat ,or even if you remove it ,
the radio will loose all the memory ,,ie all pre-set stations .
and balance levels ect
just re prog asif it were new
Do you need the code for it? If you dont have it your cars main dealer will do it for you, costs around 20 quid.
most newer car radio's have a fuse on one of the live wires it sounds like you've blew this or shorted the fuse in the fuse box when reconnecting.if you do have two live wires check that they are connected the right way round.
The trick is to plug a battery into the *** lighter socket before removing or disconnecting the main battery. I use an old sealed Motorbike battery with a plug from a plug in map reading light.
Your radio will need to have the code reset, however this is likely to be the least of your problems./
The Battery should not need rechargng, if it did why disconnect it unless you have a fast charger.
Unless you ran the battery down by leaving the lights on or something specific you need to check the charging system, , start the engine, switch as many electrical items on as you can and check the Battery voltage, it should be around 14 volts at a fast tickover, a cheap digital multimeter £ 5 from Maplin is quite adequate for this test. if the voltage is lower and is not steadily increasing, and the alternator drive belt is not slipping then chances are you need a new alternator.
If the voltage is OK and the battery is going flat, disconnect the earth wire and check the battery drain with everything switched off and the doors closed ( Interior light ) it should be less than 1/4 amp, If more check why, if less chances are you have a Duff Battery.
You probably just need the code
you need the code without this your radio wont work
you need to enter the code for your car stereo, you have not stated the make or model wether it is afactory fitted model , and how old it is .
but if you have not got all the paper work that states the radio code, you can take the stereo out and take it to a car show room (second hand dealers know the tricks or will know someone.)
they might decode it, or put a new code into it for you at a cost of around a tenner.
good luck it must be murder with no sounds.
