ECM fault code 168-1 indicates low battery voltage to the Engine Control Module, causing shutdown and electrical failures. This comprehensive guide covers diagnosis, repair steps, and prevention for diesel RV owners experiencing this critical issue.
Your modified sine wave Xantrex 758 likely caused the hair dryer malfunction due to waveform incompatibility with sensitive electronics. While some devices work fine with modified sine wave inverters, modern residential refrigerators, computers, and electronics require pure sine wave power to prevent damage and ensure proper operation.
Your Generac 7.5kW diesel generator likely has a damaged starter solenoid or starter motor from extended cranking with a weak battery. Check connections, test the solenoid, and inspect the starter before seeking professional repair.
Troubleshoot Kwikee electric RV steps. Diagnose and fix steps that won't extend or retract including motor, switch, and linkage issues.
Troubleshoot complete 12 volt power loss in RV. Step-by-step guide covering batteries, fuses, disconnect switches, and wiring.
Master your RV electrical system from house batteries to shore power. Covers 12V DC, 120V AC, inverters, and charging.
When an RV water heater pilot light won't stay lit after releasing the button, it's usually caused by a faulty thermocouple that needs cleaning or replacement. The thermocouple is a safety device that detects the pilot flame and allows gas to flow.
Keep your RV generator running reliably with this comprehensive maintenance and troubleshooting guide for Onan, Generac, and Cummins units.
Emergency start connects house batteries to chassis battery. If not working: verify house batteries are truly charged under load, listen for solenoid click when pressing button, check fuses, and verify correct activation procedure. Solenoid failure is common.
Reversed heater lines cause hot dash air while driving because coolant constantly flows through heater core. Diagnose by feeling hose temps, fix by swapping hoses or adding shutoff valve.
Hard starting often fuel pressure bleed-down from check valve or injector. Test by cycling key to build pressure. Use gauge for definitive diagnosis.
External generators need signal wire to trigger ATS, which is only connected to onboard genset. Solutions include manual bypass switch, simulating the run signal, or universal voltage-sensing ATS.
Yes, EPDM rubber roof bubbling and separation can often be repaired by cutting small slits in bubbles, removing trapped air/moisture, applying adhesive underneath, and sealing with appropriate sealant.
Rear brake lights and hazards out often common ground or connector issue. Check grounds at rear lights and chassis-coach junction.
The ignition relay on a 1988 Ford E350 (Fleetwood Tioga base) is typically located in the engine bay fuse/relay box on the driver's side firewall, or in a separate relay box near the battery. Some models may have it mounted on the firewall or inner fender well.
