Main Relay Failure Symptoms
An open circuit in the Main Relay will result in no voltage to the EMS2000 and the other components as supplied by the Main Relay.
A permanently engaged Main Relay will result in an excessive closed current draw and will lead to a dead battery.
Main Relay activation is monitored by the EMS2000. Faults will be set if the main relay is energized and power is not received by the EMS2000.
