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

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

Michelin RV Tire Problems: Complete Guide & Solutions 2024

Standing in my driveway planning to tackle these serious handling issues with my new Michelin Agilis HD Z 245/70R19.5 tires on my 2018 Winnebago Vista LX 27N this Saturday — what should I check first? The RV now has 25k miles, and since switching from Goodyear tires, I'm experiencing terrible tail wag - especially when towing my 2024 Toyota Tacoma and in windy conditions.

I've tried multiple tire pressures (82 psi from door sticker, 110 psi from installer, up to 100 psi) but nothing resolves the side-to-side movement. I have several stability modifications installed (Rear Trac Bar, Aux Roadmaster Rear Swaybar, Front Roadmaster Swaybar, Koni FSD shocks), which previously helped with handling.

The movement feels like the towed truck is actually pushing the RV's rear side-to-side, making driving extremely uncomfortable. I'm within Michelin's 60-day/2500-mile buy-back period and want to understand why these tires are performing so differently from my previous set.

Could experienced RV owners help me diagnose what might be causing these handling problems? …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

How to Replace RV Slide Topper Fabric: Complete DIY Guide 2024

I pulled into three different campsites this month and my torn slide topper is eating through my gear faster than I can replace it. I've never done anything like this before and I'm worried I might damage the whole mechanism or make things worse.

Can I actually replace just the fabric portion safely, or should I bite the bullet and have the entire assembly replaced by a professional? I'm also concerned about costs - I'm hoping this won't break the bank. If it is something I can do myself, how difficult is it really? I don't want to get in over my head and end up with a bigger problem than I started with.

Can you help me understand the best approach for my specific situation? …more

RV Slide-Out Maintenance: Complete Guide to Prevent Wear and Extend Lifespan

Before I even finish extending my 2018 Newmar 2702 slide-out, there's this grinding vibration that kicks in during the final positioning phase every single time. The motor works hardest during that last foot of travel when the slide settles into place.

This observation has me questioning optimal maintenance protocols for slide-out longevity. What are the most effective strategies for reducing mechanical wear on these systems? I'm particularly interested in understanding proper usage frequency, seal maintenance requirements, and whether partial extension during routine tasks like cleaning provides any protective benefits.

Looking for comprehensive guidance on preventive maintenance practices, lubrication schedules, and storage considerations that will maximize slide-out system lifespan while minimizing premature component failure. …more

RV Battery Draining Overnight? Find & Fix Parasitic Drain

The day after I installed that new solar charge controller last month, my RV batteries started mysteriously draining from fully charged to completely dead overnight. I've already confirmed that all visible lights, fans, and appliances are turned off, and I've switched off the main interior power, but something is still drawing power continuously. I understand this is likely a parasitic drain where some component or circuit is staying energized when it shouldn't be, but I'm not sure how to systematically track down which specific circuit is causing the problem. I have a basic multimeter but I'm not entirely sure about the proper methodology for testing each circuit individually to isolate where exactly the power draw is coming from. What's the step-by-step process for using a multimeter to methodically work through the electrical system, starting from the main disconnect and testing individual fuses or circuits until I can pinpoint the exact source of this parasitic drain? …more

How to Upgrade Progressive Dynamics Converter for Lithium RV Batteries Safely

Got a 15-year-old Progressive Dynamics converter that's starting to throw fault codes with my new lithium setup — worth upgrading or try making it work? I have a 2006 Lance 915 cabover that I recently upgraded with 2-200 watt Bouge solar panels and 2-100ah SOK lithium batteries.

The problem is I'm still running the original Progressive Dynamics converter charger that came with the RV, and I've learned it's not designed for lithium batteries. I'm worried about damaging my new battery investment.

What are my options for upgrading? I'm not sure if I need to replace the whole converter unit or if there's some kind of upgrade kit available. Any advice would be really appreciated since I don't want to mess this up! …more

Coleman Mach AC Fuse Blows With Battery On - Rockwood Fix

Found out the hard way that the previous owner of my 2019 Rockwood Minilite 2509s left me with a Coleman Mach AC that blows fuses instantly when I flip on the battery. The AC fuse blows instantly when I turn on the battery disconnect, before the AC is even activated. The fuse literally blows before it's completely seated in the panel.

This began two weeks ago without warning - the system had been functioning normally prior to this. Initial fuse replacement provided temporary operation, but the problem returned on the next trip with the fuse already blown upon arrival.

Given the immediate fuse failure with just battery power connected, what type of electrical fault would cause this symptom pattern in a Coleman Mach unit, and what's the most likely location of the problem in the AC circuit? …more

Entegra Odyssey 26M Murphy Bed Couch Replacement and Ground Clearance Upgrade

Our 2022 Entegra Odyssey 26M's Murphy bed couch just completely failed at 11 PM and we desperately need a replacement solution before family arrives tomorrow morning. What if I could swap out that murphy bed couch for some fancy theater seats? I'm picturing myself reclining in luxury while Netflix loads at dial-up speeds thanks to campground wifi.

But here's where my engineering expertise (aka zero knowledge) kicks in - can theater seats even work with a murphy bed setup? Do the backs need to come off or fold down? And while I'm dreaming big, I'd also love to get a couple more inches of ground clearance so I stop scraping on every driveway entrance like I'm driving a lowrider.

Am I asking for the impossible, or is there actually a way to make this couch-to-theater-seat transformation happen? And what's the least complicated way to get this thing sitting a bit higher off the ground? …more

RV Slide Out Moving Slowly? Complete Lubrication & Repair Guide [2024]

I tried everything I could think of, but after all that heavy rain last week, my slide out went from smooth operation to moving like molasses. It sounds like it's really struggling and straining, making these awful grinding noises that have me worried I'm going to break something expensive.

I've been reading that lubrication might be the answer, but I honestly don't know where to start. Should I be looking at the motor mechanism? The tracks? I've heard about hydraulic fluid but I'm not sure if my system is hydraulic or electric. I really need someone to walk me through what needs lubrication and what else I should check before this thing stops working completely!

Could you help me troubleshoot? Details that might help: Can you tell me the specific model of my RV and the type of slide out system it uses? …more

RV 3-Way to 12V Compressor Fridge Replacement: Cut Power Use 80%

Three weeks into owning this RV and the previous owner left me with a power-hungry Norcold 3-way absorption fridge that's absolutely demolishing my 600AH battery bank daily.

I keep hearing people rave about switching to 12V compressor fridges like the Dometic DMC4101, claiming they'll solve all my power woes. But here's the thing - everyone says "it uses way less power" but nobody gives me actual numbers! I need the cold hard facts: exactly how much power will I save making this switch? Will it really make that big of a difference, or am I just trading one expensive problem for another?

Please tell me someone has real-world experience with the power consumption difference between these fridge types! …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

How to Protect Your RV Alternator When Charging Lithium Batteries: DC-

Tried everything my neighbor did to charge his LiFePO4 batteries but mine keeps frying the alternator while his works flawlessly — what's different? I want to install a temperature sensing device that can interrupt charging by opening the solenoid between chassis and house charging systems if the alternator gets too hot. I'm looking to spec out components and understand the installation process, and I'm open to hearing why this might not be a good approach. My goal is preventing alternator overheating when these lithium batteries draw high current compared to my old flooded or AGM batteries. I'm looking for technical feedback and am totally open to critique. …more
