RV Electrical Problems: 12V & 120V Troubleshooting Guide 2024

Around $500 in parts later — replaced the main breaker, cleaned all connections, checked the transfer switch — my 2007 Holiday Rambler Admiral SE still won't recognize shore power.

I'm pretty sure 110V is making it to the rig since I can measure it, but somewhere between the plug and my appliances, something's not happy. Energy management panel is dark too. What's the logical troubleshooting order here? I keep hearing about transfer switches and breaker panels but honestly don't know where to start without making things worse! …more
Onan 5500 Generator Problems: Complete Repair Guide 2024

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

RV Inverter Guide: Modified vs Pure Sine Wave - Safe Power

My multimeter's out and I'm ready to tackle this RV electrical mess myself — pretty sure the inverter's the culprit but need to know where to start. I have a 2000 Winnebago Ultimate Advantage with four deep cycle house batteries and recently installed a Xantrex 758 inverter to replace my old Freedom 15 unit. The first time I tried using the inverter power while unplugged from shore power, something very strange happened - a hair dryer in the bathroom started running by itself and wouldn't shut off when I tried the switch. I had to unplug it, and the handle was warm. The hair dryer appears to be ruined now.

When I bought the Xantrex 758, I paid around $725 for what I thought was a good unit, but I'm now learning there's a difference between modified sine wave and pure sine wave inverters. I wasn't aware of this distinction when I made the purchase, and it turns out the 758 is a modified sine wave unit. I've since heard that modern electronics, especially things like residential refrigerators, computers, and sensitive electronic components, can be damaged by modified sine wave power.

I'm really concerned about potentially damaging my new residential refrigerator, stereo system, and computer equipment. Should I be worried about using this modified sine wave inverter with modern RV electronics? Is the hair dryer incident a sign that I need to upgrade to a pure sine wave unit, or are there other factors that could have caused this problem? I'm trying to understand if my current setup is putting my expensive electronics at risk. …more

ECM Low Battery Warning RV: Complete Diagnosis & Fix Guide

During a family trip, my 2005 Fleetwood Discovery 39S threw code 168-1 for low ECM battery voltage and went into full shutdown mode—is this dangerous with kids onboard? Engine cut out, transmission selector went dark, ABS warnings everywhere - the whole nine yards. Scared the heck out of me when it happened on the interstate!

I'm seeing this seems to be a thing with these diesel pushers, but I'm drowning in conflicting info online. Some say it's the chassis battery, others blame alternator issues, and I've even seen posts about ECM power supply problems on the Caterpillar engines. What's the actual step-by-step process to track this down? And more importantly, how do I fix it so it doesn't leave me stranded again? Really need a complete walkthrough of what causes this code and the proper repair approach. …more

RV Storage on Gravel: Preventing Weed and Moisture Issues

Nobody warned me that buying a house with RV storage meant inheriting the previous owner's 13-year-old weedy, muddy gravel disaster. While considering this location's storage options, I want to mitigate potential issues with weed growth and moisture retention under the RV.

I'm seeking advice on effective strategies for storing on a gravel surface that shows significant weed penetration and moisture retention. Initial ideas include pre-treatment herbicide application and installing a protective barrier, but I want input from experienced RV owners.

My primary concerns are preventing undercarriage damage and managing moisture/vegetation growth. I plan to spray weed killer beforehand and potentially lay down a weed barrier, pending facility approval. What techniques or materials do you recommend to protect my RV during storage? …more

Generac 7.5kW Diesel Generator Repair Guide - RV Troubleshooting

Planning to ignore the weird noises from our Generac 7.5kW diesel generator backfired when my wife pointed out I definitely made things worse during my repair attempt. I have a 2007 Monaco with a Generac 7.5kW diesel generator, and yesterday when I tried starting it, the battery was really weak. I probably held the starter button too long - maybe 15 seconds or so - because it was cranking so slowly and I kept hoping it would catch.

Now when I try to start it, I just get a single click and nothing happens. I'm worried I damaged something by cranking it so long with that weak battery. Should I be looking at the starter solenoid or starter motor? Is there anything I can check myself before I have to take it to a repair shop? I'd really appreciate any guidance on troubleshooting this. …more

RV Liquid Spring Adjustment Guide: Setup & Tuning Tips

Three different adjustment knobs on my 2022 Tiffin Open Road 34PA's LiquidSpring suspension and I'm staring at them with zero clue about the limits.

I've got LiquidSpring suspension on all four corners, but I'm specifically wondering about the rear struts. Can I raise and lower just the rear ones independently, or am I stuck adjusting everything at once like some kind of suspension caveman? I'd love to dial in the perfect ride height and handling, but I need to know if I can fine-tune the back end separately from the front. Between the control panel and what I assume is some fancy smartphone app, surely there's a way to make this old road warrior ride like a dream without turning into a mechanical engineer, right? …more
RC7-GS Inverter AGM Battery Settings: Complete Setup Guide

RC7-GS Inverter AGM Battery Settings: Complete Setup Guide

Replaced my 105Ah AGM battery and now my RC7-GS inverter charger is completely rejecting it like this capacity doesn't exist in its programming.

The charging settings only go from 125Ah up to 1000Ah, with an 'auto' option that supposedly 'learns' my battery but resets every time the low voltage cutoff trips (which feels like cheating, honestly). I'm worried about undercharging or cooking my expensive new AGMs if I pick the wrong setting.

Oh, and while we're talking about things that don't work as advertised - the generator auto-start feature might as well be a myth. Can't even manually start the generator from the RC7 panel. At this point I'm wondering if I should have just stuck with my old setup that actually worked! Anyone know what I'm doing wrong here? …more

1999 F53 V10 Oil in Coolant: Complete Head Gasket Diagnosis & Repair Guide

Called three dealerships about warranty coverage for oil contamination in my 1999 Ford F53 V10's coolant system — before I tackle this head gasket nightmare myself. The unit overheated after the oil level dropped significantly, though it still starts and runs without throwing any codes.

Based on the symptoms, I suspect a blown head gasket, but I want to perform proper diagnostic testing before committing to a major repair. What specific diagnostic procedures should I run to confirm whether this is actually a head gasket failure versus other potential causes like a cracked head or block issue?

Looking for a systematic approach to pinpoint the exact problem before I start tearing into this engine. …more

Camco Rhino Sewer Hose Adapter Pro: Complete Review & Installation Guide for RV Owners

Noticed my 2018 Forest River Cherokee's cheap sewer hose adapter keeps leaking at the connection no matter how tight I make it. The Camco Rhino Sewer Hose Adapter Pro claims it works on both threaded and non-threaded outlets with some kind of clamp system, but I'm worried about spending money on something that might not actually work reliably.

Has anyone actually used this adapter successfully? I'm particularly concerned about whether the clamp system really creates a leak-resistant seal, and if it truly eliminates the need to carry multiple adapters. My RV has a non-threaded outlet and I've had nothing but problems with adapters that don't fit securely or leak during dumping. …more

Dometic 310 Toilet Leaking at Foot Pedal: Complete Fix Guide

Called my weekend camping trip short because my Dometic 310 toilet has water pooling underneath, the flush mechanism sticking, AND that annoying gurgling sound happening constantly. I can see the leak between the fixed outer part and the moving pivot section when the pedal is pressed.

Already replaced the toilet valve but it's still leaking from the same spot. The inlet and outlet hoses look fine. What causes leaks at the pedal mechanism itself after the valve has been changed? …more

Kwikee RV Steps Not Working? Complete Troubleshooting Guide (2024)

Apparently we're leaving for a three-week cross-country trip next Monday and my Kwikee electric RV steps are still having intermittent retraction issues even after replacing both the gear box and motor. My steps are exhibiting intermittent retraction issues - they extend normally but require manual assistance to retract fully, stopping approximately a quarter inch through the cycle without intervention. I've already installed a new gear box and motor, yet the problem persists.

What systematic diagnostic approach should I follow to identify the root cause? I need to understand the complete troubleshooting sequence for motor functionality, electrical switch operation, and mechanical linkage components. Are there specific voltage measurements, resistance checks, or mechanical adjustments that should be performed to isolate whether this is an electrical or mechanical failure?

Thanks,

Best Cummins 6.7 Scan Tools for RV Diesel Diagnosis & DPF Regen (2024

The internet seems to give me six different answers about which scan tool actually works with my 2019 Fleetwood's Cummins 6.7L—am I missing something obvious here? Need comprehensive coverage for reading and clearing fault codes, monitoring engine parameters, and performing forced DPF regeneration cycles.

Considering several options including the Foxwell HD500, Ancel heavy-duty scanners, and various BlueFire/Inline adapters available through different suppliers. Price ranges vary significantly from budget OBD2 adapters to professional-grade diagnostic equipment.

Looking for detailed comparison of available scan tools specifically for Cummins 6.7 applications - both professional-grade and DIY-friendly options. What are the key features, compatibility considerations, and real-world performance differences between the various diagnostic solutions for this engine platform? …more

RV Flat Tire on Highway: Emergency Steps & Specialized Roadside Service Tips

Every highway mile seems to be eating through my Tiffin Allegro motorhome tires way faster than it should, especially after that brutal double blowout on the back axle. When this happened to us, we found that regular AAA and typical roadside assistance don't always help with RVs. We were stranded and eventually had to use a service called Driving Solutions, who charged us $1600 for used tires after eight hours of waiting.

What's the proper procedure if this happens? Should I try to move to a safer location first, or stop immediately? Who should I call for help - are there specialized services that handle RV tires? I want to be prepared with the right contacts and know the safe steps to take, because I imagine regular tow trucks and tire services might not have the equipment or expertise to handle a large motorhome tire emergency on the interstate. …more
