Your Onan 5500 generator's fuel pump chatter and dual light illumination indicates a control board communication error triggered by the remote harness connection. This comprehensive guide covers diagnosis, repair steps, and prevention strategies for all common Onan 5500 issues.
Master your RV electrical system from house batteries to shore power. Covers 12V DC, 120V AC, inverters, and charging.
Protect your RV from freeze damage with this comprehensive winterization and de-winterization guide.
Lukewarm water from your RV heater is typically caused by a failing heating element, sediment buildup, or thermostat issues. Most problems can be fixed by replacing the heating element, flushing the tank, or adjusting the thermostat.
Most RV solar systems range from 200-800 watts using 12V panels wired in parallel with PWM or MPPT controllers. Wire gauge depends on amperage and distance, with 10-12 AWG typical for most installations.
All headlights out with other lights working points to headlight relay or combination switch failure. Check and swap headlight relay first - if no change, the combination switch is likely failed. Common issue on late 90s Ford chassis.
F53 460 timing marks on harmonic balancer viewed through timing pointer. Clean and mark with white paint for visibility. Use timing light at idle.
Hydroboost systems use power steering fluid pressure to assist braking instead of engine vacuum. A leak can eventually cause loss of both power steering and power braking if the reservoir runs dry, but you'll retain manual operation.
Furnace running 5-10 minutes then quitting usually indicates overheating from restricted airflow, weak flame, or failing control board. Check combustion air intake, propane pressure, and burner flame quality. Control board becomes suspect if other tests pass.
Your 2015 Vista's V-10 pulsing issue that started after mountain passes in Montana is likely caused by a failing mass airflow sensor, throttle position sensor, or fuel delivery problem. The "Fault received from External Node" code suggests a communication issue between engine management and instrument cluster that may be related.
Key issue is only 3.3V at fuel pump relay trigger instead of 12V. This prevents relay activation. Trace the wire feeding relay pin 86 to find voltage drop. Check for bad connections, corroded grounds, or damaged wiring between power source and relay.
Your unprogrammed Ford F53 transponder keys will continue working indefinitely, but they lack anti-theft security features. Programming adds immobilizer protection but isn't required for basic operation.
When your RV propane furnace clicks but won't light, it's usually caused by a dirty or failing igniter, blocked air intake, low propane pressure, or faulty control board. Most issues can be resolved by cleaning the igniter, checking propane supply, and ensuring proper airflow.
Yes, HWH systems typically use 1/4" ID hydraulic hose. You can repair with a compression coupling, but you'll need to bleed the system afterward. This is a moderate DIY repair if you have the right tools and fittings.
Your Dometic 12V compressor refrigerator likely isn't getting adequate power from your batteries. Check battery voltage under load, inspect connections for corrosion, and ensure your battery bank can handle the high amp draw required for the compressor.
