Engine Electrical Systems issues, I believe. Digital Multi-meter required for this diagnose. then Check Starting/Charging System: Battery Conditions: state of charge-cell electrolyte gravity, Open circuit voltage, battery load test, Battery Cables and connections(NEG battery terminal and connections to Battery- Chassis, Battery-Engine, Engine to Firewall: recharge/repair or replace as needed. Charging System Voltage output (Engine running) and voltage drop test. Thanks
Check battery, main power and grounds for clean connections. Any kind of corrosion on connections and inside the cables can lead to no power anywhere.
