test the battery with a volt meter.

The battery is made by Gruber Power and is rated at 12 volt-10.5 amphour.
I have tested the battery with a digital multi-meter which is how I know it always reads 13 volts...Yes there were signs of electrolysis on the 2 male prongs going into battery box. Sanded them clean and no difference on the depth readings. 13 volts on battery, and 13 volts coming out of the battery box connector.

Also checked to make sure I don't have the depth alarm set...
