Hi my name is***** will be glad to help. Check the IGN switch for shorts and confirm power in and out of the switch in each position and that power runs through the switch when it should be. Also check all relays for the possibility of them sticking. If ok thoroughly inspect the harness for chafed or shorted wiring and for damaged pins inside the connectors. If the harness checks ok you will be looking for faulty ground connections, Overcharging charging system ( Alternator faulty/backfeeding), or a faulty monitor. Let me know
