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 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.
The RC7-GS inverter charger can properly charge 105Ah AGM batteries using the 125Ah setting, as AGM charging is voltage-based, not capacity-dependent. Generator start issues typically stem from wiring problems or incorrect DIP switch configurations.
Guide to safely updating RV infotainment and navigation systems. Covers finding valid updates, preparation steps, and troubleshooting common issues.
Expert guide to RV 12V DC electrical systems. Covers batteries, wiring, voltage monitoring, and system upgrades.
Master your RV electrical system from house batteries to shore power. Covers 12V DC, 120V AC, inverters, and charging.
Troubleshoot house batteries dying while on 50 amp shore power. Diagnose converter, breakers, and connections to restore proper charging.
A gas detector that beeps every minute during nighttime hours (7PM-7AM) is typically experiencing low voltage issues, sensor degradation, or interference from temperature changes and humidity. The timing pattern suggests power-related problems rather than actual gas leaks.
Keep your RV generator running reliably with this comprehensive maintenance and troubleshooting guide for Onan, Generac, and Cummins units.
Your 1993 American Eagle's Onan generator producing only 12-15 volts indicates a faulty rectifier bridge (part CR21) or suppressor (part RV21). The correct replacement parts are 305-0696 for the rectifier bridge and 305-0703 for the suppressor.
An inverter beeping three times and shutting off typically indicates low voltage under load, overheating, or overcurrent protection activation. While your batteries show 12.8V at rest, they may drop significantly under load due to poor connections, battery degradation, or undersized wiring.
Guide to RV battery disconnect switches. Covers when to use, what loses power, and best practices for storage and daily use.
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.
Protect your RV from freeze damage with this comprehensive winterization and de-winterization guide.
RV air conditioners freeze up due to restricted airflow, dirty filters, low refrigerant, or thermostat issues. Turn off the AC, let ice melt completely, then clean or replace the air filter and check for blockages.
