I always leave my radio on, but recently the battery was removed from the car, my deck hasn't come on since. Had a friend check the fuses, they seem to be ok, what else could be the problem?

double check all your connections. you can always bench test the radio with a car battery and any speaker. find your 2 hot wires and 1 ground. (1 hot wire is for memory, but with some radios it will need power also to bench check) make sure all your radio fuses are good, run a set to the speaker, then run the wires to the battery. if the radio powers up, the problem isn't the deck. this has worked for me several times.
you can skip connecting the speaker, but I prefer to make sure everything works before I reinstall.
Some newer cars leave the radio on after the key is removed for a preconfigured period of time. If the radio shuts off when the door is opened, this is normal activity.
If the radio is aftermarket and was recently installed, the power for the unit was pulled from an always-on source, instead of an ignition switched source. Changing the power lead to a circuit that is switched with the key will fix it.
remove the trim plate(thin plastic strip around your deck) you will see on the center of each side slots for two thin deck keys these always come with a new deck. you you dont have them ask a friend who has recently bought a deck(any make should be fine) or go to your local best buy and ask for a set MAKE SURE YOU ASK FOR THEM FOR FREE unless the installer you asked has purchased his own universal keys they will give you them.
a little more information would be nice but im going to make a guess
you installed a new deck in the car, now every time you turn the car off the clock resets?
if thats correct..
the deck will have 2 power inputs, one that turns the radio off when it does not have a power signal, the other that should have a constant voltage to maintain the stereo memory, now if I'm correct you have either the 2 wired opposite to how they should be or both wired to something like the ignition wire, and it is acting like the battery has been removed every time you turn off the car, which means you need to check your stereo wiring.
if this is incorrect please leave some more info telling everyone when the clock is automatically reseting.
your deck has two power sources a main for when your car is turned on so the radio kicks on and a remote which is always on keeping stations and clock powered passively so whoever installed it did it improperly or do to road wear and tear it was jossled lose and can simply tightened after pulling the deck out
disconnect the battery and measure the current flow.
measurement of more than 100ma (1/10 amp) will drain the battery.
if you have an external power amp connected,check to see that the "remote" is working correctly and not leaving the amp on.
If it only the deck by inself,take out it's inline fuse and see if the battery is still losing power.
Maybe the installer has made a mistake
most aftermarket units have 2 power wires 1 for the battery and 1 for a keyed hot source,what you need to do is hook both of them up to a constant (battery) power source,be sure and include an in-line fuse.
Hi. SOunds like another case of power problems. Your deck has 2 power wires. One is yellow th eother is red. One is constant 12 volt battery power, the other is a switched 12 volt power, only has power with the ignition key on or on accesory. Get yourself a test light. I almost bet you do not have the constant 12 volt power to the deck, therefore your deck cannot hold its presets...
