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.
![RV Slide Out Moving Slowly? Complete Lubrication & Repair Guide [2024]](/images/categories/slideouts.jpg?v=1767805076)
A slow-moving RV slide out typically needs lubrication on the motor mechanism, gear tracks, and slide rails. Check hydraulic fluid levels on hydraulic systems or inspect motor connections on electric systems for proper operation.
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.
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.
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.
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.
When your RV has no power despite being plugged into a working campground pedestal, the issue is typically a bad shore power cord, faulty transfer switch, or tripped main breaker inside the RV's electrical panel.
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.
Slide losing stop points indicates power interruption or failing controller memory. Check all power connections at controller for tightness. If happens after battery disconnect, some systems reset by design. Persistent issue may require controller replacement.
Shutting down under load after rebuild suggests carburetor still not delivering enough fuel or governor sticking. Watch governor arm movement during load test. Try gradual load increase to find threshold. Check fuel pump output if equipped.
F53 460 timing marks on harmonic balancer viewed through timing pointer. Clean and mark with white paint for visibility. Use timing light at idle.
When your HWH Spacemaker slide motor runs but won't extend, the most common causes are a faulty extend solenoid, hydraulic leak, or safety lock malfunction. Start by testing solenoid operation and checking for hydraulic fluid leaks at the slide cylinder.
