After a minute or so of running the flickers

Sounds like you may have a bad diode in the alternator, make sure all of the lights are off and the doors closed, disconnect a battery terminal and put a test light in between the cable end and the battery, if the light turns on then disconnect the alternator electrically, if the light goes out then you have a bad diode, if you don't get a light then reconnect the battery cable and get an analog voltmeter and connect to the battery, start the engine and watch the voltage, it should be stable, not bouncing, if it is you may have a bad voltage regulator or a bad ground to the alternator and or engine block.

All of the above is assuming you have a good battery.

2 years I've had the battery. But I'll give it a try when I leave work. Thanks
