Drain on battery

[lil754boy]

I have a drain on my battery when engine not running. What should I check. I have been told it could be the alternator. How should I test this to determine the problem? I have had the battery and alternator tested twice and both determine the alternator is good.

How much of a drain is it? It could be a faulty alarm, the HU, an amp, the alternator.......

Put a meter in series with positive of battery and start pulling fuses
You will see right away what circuit has trouble this way by watching meter
