If you check with a multimeter directly onto your alternator terminal with one end and to earth with another with the engine running you should be getting output if none then the alternator is not working as intended.

have you tried refitting the after market cd player as this could be cause of fault

Check readings at alternator, If the alternator is working well, your multi-meter should read somewhere in the vicinity of 14 volts (typically 13.8). If it is reading excessively higher than 14 volts (greater than 15 volts) it is possible that the voltage regulator on your alternator is faulty or going bad (try turning everything on in car) If it is reading lower than 13-14 volts, bring up eng revs to 2000 if still not right check cable mate if still bad you know wear the fault is mate
