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.
Keep your RV generator running reliably with this comprehensive maintenance and troubleshooting guide for Onan, Generac, and Cummins units.
Fix your RV refrigerator with this guide covering Dometic, Norcold, and residential fridge issues.
House battery at 11.2V is critically low. Connect shore power immediately to charge via the Xantrex built-in charger. Investigate why solar and normal charging failed.
Yes, high-output alternators can be installed on your F53/Triton V10, but you'll need to upgrade wiring and possibly the serpentine belt system. The Tucson unit you found is a solid choice for your large inverter battery bank needs.
Your Ford E350 Class C likely has a factory-installed charge isolator or solenoid limiting current to 20 amps to protect the original lead-acid batteries. This is normal behavior and adding a DC-DC charger was the right solution for lithium batteries.
LED tail lights on Workhorse cause slow flash or solid indicators. Fix with LED-compatible flasher relay, load resistors, and dedicated ground wires for each light.
Worn Onan 10KW generator mounts cause vibration and noise. Replace with OEM parts from Cummins dealer. Most owners have shops do this due to generator weight and access challenges.
Add minivan seats to your RV by mounting securely to floor joists with grade 8 bolts. Include proper seatbelts at each position. Elevate seats with plywood platforms if needed for clearance.
RV dual indicators typically show paired readings like fresh vs gray water levels, house vs chassis battery, or current vs set temperature. Check your RV manual or panel manufacturer for specific meanings.
Protect alternator from lithium battery high current draw using DC-DC charger for current limiting or temperature-controlled relay. DC-DC charger is best solution. Direct connection without protection risks alternator failure.
When your Fleetwood Bounder's ignition switch isn't getting power despite good fuses and relays, check the ignition feed wire from the battery junction box, inspect the main power distribution connections, and test the starter relay circuit which often feeds the ignition switch.
If suspension and frame are square but body sits low on one side, the issue is body mounts. Check for loose bolts, failed rubber isolators, or manufacturing variance. Body shims can correct this. Since its a 2021, contact Jayco about warranty coverage.
Onan generator isolators available from Cummins dealers, RV parts suppliers, or industrial suppliers like Grainger. Measure bolt size and diameter to match if using generic mounts.
12V fridges draw 3-6 amps and your tow vehicle should provide enough charging through 7-way connector. Check voltage at trailer while towing - should see 13.5V+ if charging properly.
