Onan 5500 Generator Problems: Complete Repair Guide 2024

Spent three hours testing my 2014 Hurricane's Onan 5500 gen getting 11.8 volts output when every manual says it should be 12+ volts! Here's the weird part - when I disconnect the remote harness, the generator fires right up and purrs like a kitten. But the second I plug that remote connection back in, boom - both the remote start light AND the generator start light come on, and then... nothing. Won't start at all.

The really bizarre symptom is this chattering from the fuel pump when the remote is connected. I can literally feel the fuel line jumping around when I put my hand on it. It's like the pump is having some kind of seizure or something!

I'm guessing this has to be some kind of electrical issue between the control board and the remote system, but I've never seen anything quite like this before. Anyone dealt with this specific combo of symptoms on an Onan 5500? Really hoping there's a known fix because pulling this thing out of the RV again would be a major pain! …more

Monaco Diplomat Rear Air Suspension Won't Dump Fully - Troubleshooting Guide

Last week my 2006 Monaco Diplomat's rear air bags started refusing to dump all the way down when I hit the air dump before leveling. The front dumps fine, but the back stays partially inflated.

I'm still pretty new to RV maintenance and not sure where to start troubleshooting this. Should I be hearing air escaping when I activate the dump? What are the most common causes when rear air bags won't dump completely? Any guidance on what to check would be really appreciated! …more

RV Grey Water Tank Clogged? 7 Proven Solutions to Clear Blockages Fast

Found out my RV service tech wants $800+ to replace the entire grey water system on my 2007 RV for an intermittent blockage that seems fixable. It doesn't seem to matter if we're level or not - it's completely random.

I've tried using a high suction shop vac and even attempted snaking it, but I'm nervous about forcing things and making the problem worse. I suspect it might be a manufacturing plug that fell into the tank, but I'm not sure. I found one solution with a reverse flush valve that seems to work temporarily, but I'm concerned about the underlying cause.

What are the safest and most proven methods to diagnose and fix these random grey water blockages? I don't want to damage the tank or create bigger problems, but this unpredictable draining is driving me crazy. Are there specific cleaning products or techniques that actually work without risking harm to the system? …more

Ford F53 RV Chassis: All Headlights Out - Complete Diagnosis & Repair

Pulled out my multimeter on this dead F53 headlight situation and I'm getting 12.4V at the relay when every Ford manual says it should read 12.6V. My 1999 Mountain High Pinnacle Class A with 76,000 miles on a Ford F-53 chassis has me stumped - ALL four headlights (both high and low beams) just went completely dead, but here's the weird part: every single other light works perfectly. Taillights, brake lights, turn signals, markers - they're all fine.

When the headlight switch is on, there are no headlights at all, and the blue high beam indicator remains constantly lit. I noticed a strange clicking sound from under the hood about every 20-25 seconds, which continued even after disconnecting the coach and chassis batteries.

I've already replaced the headlight switch thinking that was the culprit, but the same problem persists. No headlights whatsoever when I flip the switch, whether I'm on high or low beam. I'm starting to think it might be the combination switch or maybe a relay with a potential dead short, but I don't want to start throwing parts at this thing without some guidance.

Has anyone dealt with this exact scenario on a late 90s Ford chassis? What should I be checking first? I really need to get this sorted out before my next trip. …more

HWH 625S Slide Out Not Working: Step-by-Step Control Box Bypass & Repair Guide

Wondering why my 2008 Winnebago Adventurer 38J's HWH 625S slide out won't budge after replacing the solenoid, cleaning connections, and checking fluid levels? The passenger slide won't extend or retract from the wall switch, but when I manually operate the solenoid valves, the slide moves perfectly in both directions.

I've already replaced the solenoid valves, so I know they're good. The problem seems to be that power isn't reaching the solenoids from the switch - everything routes through the control box first.

Can I safely bypass the HWH control box by connecting the switch wires directly to the solenoid wires? What should I check before attempting this bypass? …more

Onan 7000 Generator Low Voltage to Fuel Pump: Complete Repair Guide

Our Onan 7000 Marquis generator is hitting us with low voltage to the fuel pump for the third time this season and I'm done with guessing games. When I check the voltage at the fuel pump, I'm only getting 9V instead of 12V, and surprise surprise - it won't start. But here's the kicker - if I jump 12V directly to the pump, the thing fires right up and runs like a champ.

Obviously there's a voltage drop happening somewhere between the control board and the fuel pump, but I'm not sure where to start looking. Could be corroded connections, maybe the control board itself is going bad, or some wiring issue in the fuel pump circuit? Anyone dealt with this before and know the most common culprits? …more

Why Your RV Generac Diesel Generator Shuts Off After 2 Minutes Under Load: Troubleshooting Guide

Found that ever since those heavy rains last month hit, my 2007 Alfa's Generac 7.5kw diesel generator shuts down exactly 2 minutes after firing up the basement AC.

Just did a full service (oil, filters, the works) so it's not basic maintenance stuff. I can restart it right after it shuts off, but if the AC is still calling for power, it dies immediately again. No error codes or blinking lights to give me a clue.

Is this a fuel delivery issue where it can't keep up with the AC load? Or am I looking at something else entirely? Really hoping someone's dealt with this exact same 2-minute thing before! …more

1999 Pace Arrow F53 Fuel Pump Replacement - Expert Advice

According to my troubleshooting so far, I've replaced the fuel filter, cleaned the fuel lines, checked all the connections, and even swapped relays — but my 1999 Pace Arrow F53 still won't get fuel to the engine. The original fuel pump has been operational for 27 years, exposed to gasoline storage conditions throughout this period.

Given the extended service life and potential for roadside failure, I'm evaluating whether proactive fuel pump replacement represents sound maintenance strategy. Seeking technical assessment on replacement timing and expected performance outcomes with quality aftermarket units from established suppliers.

What are the documented results from similar preventive fuel pump replacements on this chassis configuration? Is the investment in preemptive replacement justified based on reliability data? …more

How to Convert Propane RV Generator to Diesel: Complete Fuel System Guide for Safe Installation

Before our two-week cross-country RV trip next month, I need to figure out this propane-to-diesel generator conversion because I'm getting conflicting advice and hearing horror stories about fuel starvation. My biggest concern is that if I just tap into the main fuel line with a simple tee fitting, I might end up starving either the engine or the generator when they're both running.

I'm worried I could damage something expensive or even create a dangerous situation. What are the proper ways to set up the fuel delivery system for a diesel generator conversion? I definitely don't want to just wing this - I need to know the safe, correct methods before I attempt anything. Should I be looking at a completely separate fuel system or are there ways to safely share the main tank? …more

RV AC Humming But No Air Flow? Fix It Yourself (2024 Guide)

I tried everything I could think of, but probably a dumb question—why would my 2006 Sightseer 30B's AC hum after storage but blow zero air? big mistake lol. The thing is humming like crazy but zero air coming out of any vents. It's loud enough to wake the neighbors but doing absolutely nothing.

I'm guessing something got stuck or seized up while it was sitting? Anyone know what typically causes this after long storage periods? Really hoping it's something I can fix myself before calling a repair guy. …more

Kwikee Steps Won't Extend: Complete Troubleshooting & Repair Guide

Every time I open my RV door these Kwikee steps stay stuck at 90% retracted — should I drop $300+ on replacements or try fixing first?

I'm pretty sure this is either a motor that's given up the ghost or something's binding up in the linkage, but I'd love some confirmation before I start throwing parts at it. Should I be checking for 12V at the motor first, or am I overthinking this? And while we're at it, any preventive maintenance I should do to keep this from happening again? Because apparently my RV has commitment issues with working components. …more

Lippert Leveling Jack Service Near Vermont: Mobile Repair & Troubleshooting Guide

Between our last camping trip and now, my Class C's rear passenger leveling jack won't respond anymore—the thing's completely stuck and the control panel keeps flashing a "Service needed" message. Pretty sure it's a Lippert system since that's what most manufacturers use.

I'm in Vermont and honestly having zero luck finding anyone local who works on these things. Starting to think I might need to drive halfway across the country just to get this fixed! Anyone know some tricks to find service around here, or maybe some troubleshooting I can try myself before I start calling around? Really don't want to be that guy camping with a busted leveler all season. …more

Ford F53 Motorhome PCM Failure: Complete Diagnosis and Repair Guide

Replaced the PCM on my 1999 Holiday Rambler Ford F53 chassis but still getting complete power loss with coil malfunction codes hitting an entire engine bank. That seems weird, right? Like what are the odds ALL the coils on one side would go bad at once?

I finally wrestled the PCM out (what a pain!) and found some discoloration on one side of the circuit board. Been reading online and seeing mixed info - some say it's the ignition system, others pointing to PCM failure. Really hoping it's not the PCM since those aren't cheap, but the whole bank thing has me wondering. Is this actually pointing to the computer being fried rather than ignition problems? …more
