    Use a voltmeter connected between the BATT– terminal (P4-49) and the sender negative terminals on the DGC-2020HD to verify that there is no voltage difference at any time. Any voltage differences may manifest themselves as erratic sender readings. Wiring should be corrected so that no differences exist.
