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

MagnaSine MS2012 Inverter Replacement Guide - Best Upgrade Options 202

About my 2007 Fleetwood Bounder: the MagnaSine MS2012 manual claims it should handle my loads perfectly, but this inverter keeps failing on me anyway. It's been acting up for months now - the microwave keeps causing it to hiccup and shut off, then it comes right back on. I know it's only going to get worse from here.

I've been looking at upgrading to something more reliable, maybe a Victron or another brand, but I'm honestly overwhelmed by all the options out there. What are the best replacement inverters that other RVers have had success with? I just want something that's going to work consistently without all these random shutdowns.

Before I spend a bunch of money though, could this actually be a battery issue instead of the inverter itself? I'd hate to replace a perfectly good unit if the real problem is somewhere else in the system. …more

1993 American Eagle Onan Generator Low Voltage Fix: Rectifier Bridge Corrective Steps

Tried everything to fix my 1993 American Eagle's Onan generator low voltage issue — about to buy a $150 rectifier bridge but is it actually the solution? Everything seems to run fine - it starts up without issues and sounds normal - but I'm only getting 12-15 volts output instead of the proper voltage I should be seeing.

I've been doing some research and think it might be related to the rectifier bridge or suppressor components, but I'm not entirely sure. The service manual mentions parts CR21 and RV21, but I'm honestly a bit overwhelmed trying to figure out exactly which replacement parts I need.

Could someone help me understand what's likely causing this low voltage issue and point me toward the correct replacement parts? I'd really appreciate any guidance from those more experienced with Onan generator repairs. …more

Onan 5500 Generator Shuts Down Under Load: Troubleshooting Guide

Onan 5500 runs perfectly at idle but kills itself within 30 seconds of turning on the AC. Been fine for years and suddenly can't handle any real load. Fuel filter is new, oil is fresh, and it starts right up every time — just dies the moment I ask it to actually work. …more

Onan 4000 Generator Won't Start Without Choke: Code 14 Troubleshooting Guide

Halfway through another camping trip and trying to decide between babying my Onan 4000 with manual choke every startup or finally fixing this Code 14 nightmare. Let me try again:

Just found out that my 2013 Thor Class C's Onan 4000 generator won't cooperate after sitting since March, and I'm dealing with a nightmare. Been getting Code 14 errors and spent half the morning just trying to get it fired up.

The only way I can get it started is by manually messing with what I think is the choke linkage - otherwise it just won't go. Once I shut it off, same story - won't restart unless I physically manipulate that linkage again. Only has 240 hours on it and was serviced about 2 years ago.

I'm pretty sure the carburetor is gummed up from sitting, but what exactly does Code 14 mean? And more importantly, what do I need to clean to get that choke working automatically again? I really need to get this thing running properly before our next trip! …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

Onan 7500 QD Code 36 Fix: How to Solve Generator Overfill Oil Shutdown Problems

Woke up this morning to fire up my Onan 7500KW QD for camping season, and that dreaded Code 36 shutdown nightmare is back again. I can restart it after waiting a bit, but this is driving me nuts.

I've been digging around online and came across something weird - apparently these dipsticks are calibrated wrong? Some folks are saying you're supposed to keep the oil level just above the 'ADD 1QT' mark instead of at the full line to avoid overfill shutdowns. That sounds backwards to me, but I'm seeing it mentioned everywhere.

Before I start messing with oil levels or throwing money at fuel pumps and control boards, can anyone confirm if this dipstick thing is actually legit? Really hoping it's something this simple! …more

Onan 4KY Generator Starts Then Dies: Oil Pressure Sensor Troubleshooting Guide

About to sound like a total newbie here, but why does my 2018 Winnebago Spirit's Onan 4KY-26100R generator start perfectly then instantly die when I release the start switch? I suspect it's the oil pressure sensor based on what I've read, but want to confirm this diagnosis before ordering parts. Oil level appears normal. I've tried locating the oil sensor near the oil filler tube on the crankcase, but it's difficult to see or reach. Is there a way to test if the oil pressure sensor is actually the problem? Can I bypass it temporarily to verify that's the issue? …more

How to Fix Generac RV Generator Oil Leaks After Breather Hose Replacement Guide

Looked like a simple breather hose replacement on my Generac RV generator, but ever since I finished the job, oil has been leaking everywhere. I replaced the cracked original-style breather hose with a new version that now includes an elbow and short extension inside the air filter housing. While the hose replacement definitely helped reduce the oil drip, I'm still seeing some persistent leakage underneath the unit.

The new hose design appears to be an upgrade from Generac, with the uphill extension meant to help oil sucked from the crankcase run back down into the engine. I'm hoping this will further minimize the drip issue. I want to make sure I'm not missing something obvious before I take it to a repair shop. Has anyone else experienced similar issues with their Generac generator's breather tube? Any guidance on troubleshooting would be really appreciated. …more

RV AGS Generator Shutdown Trips Inverter Off - Complete Fix Guide

Opened my 2006 Fleetwood Providence yesterday to find my Onan 7500 generator automatically shutting down and tripping my Xantrex Freedom 458 inverter off every time.

The AGS does its job perfectly - kicks on when needed, charges the batteries, then shuts down like a good little robot. But here's where things get spicy: about half the time when the generator shuts off, my inverter decides to throw a tantrum and shut itself off too. Then I get to do the walk of shame to hit the reset button like I'm apologizing to a moody teenager.

This has been going on for literal years, and I'm tired of playing referee between my electrical components. Anyone know what's causing this voltage drama and how I can make these two play nice together? Is it a transfer switch timing issue, some kind of sensitivity setting, or do I just have the world's most dramatic RV electrical system? …more

How to Fix Onan Generator That Won't Stay Running After Running Out of Gas

Halfway through our camping trip, my Onan 4KY-26100R generator on a 2018 Winnebago Spirit is doing something bizarre — firing up perfectly after running out of gas but dying within minutes. After refilling the tank and changing the oil, the generator starts but immediately shuts off when I release the start switch. Getting 3 flashes on the control switch indicating service required. Oil level is correct - halfway between add and full marks. Is this an air in fuel system issue from running out of gas? How long should I hold the start switch to get it running again? …more

Cummins Onan Generator Service: What to Do When Dealers Won't Service

Called three Cummins dealers about servicing my 12-year-old Onan generator and they all said it's "too old," but my neighbor's same-age unit gets serviced just fine. My generator is about 12 years old and needs some work done on it.

I'm feeling a bit overwhelmed - are there other options for getting older Onan generators repaired? I'm worried I won't be able to find anyone to work on it or get parts. Any guidance would be really appreciated since I'm not sure where else to turn for service on older equipment like this. …more

Is It Safe to Sleep with Your RV Generator Running? Safety Guide 2024

This is 11 PM and my wife is sweating bullets in our RV — need to know if running our generator overnight is safe before we both melt. We have a 2023 Class C RV and my wife really needs the A/C running at night to sleep comfortably. I know our RV has a carbon monoxide detector installed, but I'm honestly not sure if that's enough protection.

I've heard mixed things about running generators while sleeping - some people seem to do it regularly while others say it's dangerous. What safety precautions should I be taking if we do this? Should I be worried about which windows are open or wind direction? I want to make sure we're being as safe as possible but also want my wife to be comfortable. Any guidance from more experienced RVers would be really appreciated! …more

Ford V10 Fuel Pump Driver Module Location: Allegro Bus FPDM Replacement Guide

Between now and our cross-country departure next week, my 2006 Allegro Bus motorhome with the Ford V10 engine started having intermittent starting and stalling issues. After doing some research and talking to other RV owners, I've narrowed down the potential culprit to what appears to be a failing Fuel Pump Driver Module (FPDM). From what I understand, this is a pretty common failure point on these Ford V10 engines, especially in the motorhome applications.

The symptoms I'm experiencing include occasional hard starting, particularly when the engine is warm, and intermittent stalling while driving - sometimes the engine will just cut out for a second and then come back to life. I've checked the obvious things like fuel filters and basic electrical connections, but everything seems fine there. Multiple sources are pointing me toward the FPDM as the likely cause.

I'm ready to tackle this repair myself, but I need to know the exact location of this Fuel Pump Driver Module on the Allegro Bus chassis. I've heard it's a small black module with a single electrical connector, but I haven't been able to locate it yet. Can someone tell me specifically where Ford mounted this component on the 2006 Allegro Bus with the V10 engine? I want to inspect it first and possibly replace it if it shows signs of failure or corrosion. …more

Used Onan 4000 Generator Buying Guide: Essential Inspection Checklist for RV Owners

Spent an hour inspecting this Craigslist Onan 4000 from Villa Rica and it's doing something bizarre — everything looks perfect but won't even attempt to turn over.

The original link was https://atlanta.craigslist.org/wat/rvs/d/villa-rica-onan-cummins-generator/7895531063.html.
