    Regulator or bad diodes in the alternator. Disconnect the big wire on the alternator and try your test again. Do not let the alternator wire touch ground

    It could be a number things that cause the parasitic battery drain, however the alternator in our model is the most common issue usual due to a bad rectifier or voltage regulator which usually means a new alternator anyway.

    I had the same battery drain issue and it was the alternator, however since you have a water leak the issue could be from shorted electronics.
