Put a voltmeter across the posts of the aux battery and take a reading.  Now
start the car and see if the reading increases (with the engine running).
If so, then you are charging the aux battery.  Now shut the car off and give
someone a jump start from your main battery (or do something else to
discharge your main battery); the aux battery voltage reading should not
change.

The idea is that the relay separates your batteries unless the alternator is
producing current.
