RV Backup Camera Not Working? Complete Troubleshooting Guide

Spent all winter enjoying a perfectly working RV backup camera, but the second temperatures hit 85 degrees outside, my screen goes completely black. My wireless backup camera decided to give me the silent treatment right when I need it most. The monitor is just sitting there mocking me with a "no signal" message, and honestly, my spatial awareness isn't what it used to be.

The camera worked fine on our last camping trip (when I only needed to back up twice), but now that I'm trying to navigate tight campground spots, it's gone completely dark. I'm dealing with a wireless system, so I know there are more things that can go wrong than with a wired setup.

Before I resort to using my spouse as a very expensive parking sensor, what's the best way to troubleshoot this? I'm hoping it's something simple like a loose connection rather than having to explain to my insurance company why there's a picnic table embedded in my bumper. …more

RV Chassis Battery Draining & Dead Outlets - Troubleshooting

Finally followed the manual's advice to check the converter first when my outlets died, but my RV chassis battery keeps draining even though the converter tests perfectly. here and I'm at my wit's end with my 2018 Winnebago Vista. The chassis battery keeps going completely dead every few days, even when we're plugged into shore power at the campground. I've already replaced the battery twice thinking it was just old, checked all the obvious stuff like dome lights and radio, and even had the alternator tested - everything checks out fine.

What's really driving me crazy is that this just started happening about a month ago out of nowhere. We've been full-timing for three years without any major electrical issues. I'm wondering if there's some parasitic draw I'm missing or if the battery isolator could be acting up? Has anyone else dealt with this nightmare? I'm getting tired of jump-starting this thing every other day and my wife is about ready to sell the rig and get a travel trailer instead! …more

RV 12V Lights Dimming: Complete Troubleshooting Guide

My neighbor insists it's the converter, the RV dealer swears it's bad wiring, and every YouTube video claims it's a dying battery—but my 12V ceiling lights keep dimming! One evening they're blazing bright like a casino, the next morning they're giving off all the enthusiasm of a sleepy firefly.

I've already checked my batteries, and they seem to be charging fine and in good shape. The converter is still humming and its fan is running normally. I'm pretty sure this isn't some fancy mood lighting feature I accidentally activated (though knowing my tech skills, anything's possible). The dimming seems totally random - sometimes they're fine, sometimes they look like they're on their last legs.

I've got a basic multimeter that I pretend to know how to use, but I'm not sure where to even start poking around. As a bonus weirdness, some of my under-cabinet light switches and the wall switch for the ceiling lights are getting really hot. Anyone know what typically causes this whole disco light show situation with 12V lighting systems? …more

RV 12V Auto Reset Breaker Size Guide: 30A, 40A, 50A Selection

Opened up my RV this morning to prep for our two-week cross-country trip tomorrow and the electrical system keeps tripping the breaker every time I run basic appliances! My RV's entire 12V system just died completely - no lights, no water pump, nothing. I've checked everything I can think of and I'm pretty sure it's the auto reset breaker that's failed.

I have a WFCO converter/charger setup with dual 6V batteries, but I can't get underneath right now to read what's stamped on the current breaker. I need to order a replacement but I'm not sure what amperage to get. I keep seeing 30A, 40A, and 50A options online but I don't want to guess wrong and either undersize it or waste money.

What's the typical auto reset breaker size for this type of setup? Is there a standard that WFCO usually pairs with dual 6V battery systems? …more

MagnaSine MS2012 Inverter Replacement & Upgrades

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 Fix a Seized RV Side Mirror - Complete Repair Guide

Already picked up this 2002 Georgie Boy motorhome and I've never dealt with a seized side mirror adjustment mechanism before — the ball joint and set screws won't budge at all. I've been wrestling with this for weeks now and I'm getting nowhere!

Before I give up and start looking at replacements, is there any way to free up seized mirror adjustments? I'm also wondering about the electrical connections - if I do need to remove the mirror (it's held on with 3 screws), how do I safely disconnect those electric cables that run to the dash controls? I really don't want to damage the wiring harness on top of everything else. …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 Underbody Lighting Installation: Complete DIY Guide

I'm wondering if anyone else walked out this morning and spotted how embarrassingly bland their RV's underside looks compared to those slick LED setups online? My husband and I are pretty new to the RV world and I've been wanting to add some nice ambient lighting underneath our Class A motorhome. I think it would look really cool when we're set up at campsites in the evenings. I've seen other RVers with these gorgeous blue or white lights that make their rigs look so professional. We're definitely beginners when it comes to electrical work, so I'm hoping someone can walk me through what's involved. Is this something we can tackle ourselves or should we find a professional? Any product recommendations would be super helpful too. Thanks so much for your patience with us newbies! …more

RV Windshield Washer System: Complete Maintenance Guide & Troubleshooting Tips

Somewhere between following three different YouTube tutorials, I managed to turn my RV's windshield washer repair into a sprinkler system that hits everything except the actual windshield. The specific issue I'm experiencing is fluid running back into the reservoir after each use, which means washer fluid isn't effectively hitting bugs before they dry and smear. I actually found a clever solution - using an aquarium air pump check valve from PetSmart for just $3.00. Sometimes it's these little fixes that make a big difference.

Sometimes the washer sprays like a garden sprinkler gone rogue, other times it dribbles like a leaky faucet. The fluid seems to have a mind of its own - either freezing up in cold weather or not hitting the windshield where it's supposed to.

I'm dealing with nozzles that spray everywhere except where the bugs are, a reservoir that I can never seem to locate when it's empty, and wipers that just smear everything around instead of actually cleaning. Could someone help me troubleshoot and confirm if my check valve solution might help? …more

RV Alternator to Lithium Battery Charging: Complete DC-DC Wiring Guide for Safe Installation

Last week I picked up my 2007 Holiday Rambler and discovered the previous owner left the alternator-to-battery charging system a dangerous wiring disaster that could destroy my new lithium batteries.

I'm upgrading from four 6V lead-acid house batteries to lithium, and I keep reading conflicting advice about alternator charging. Some people say "just connect it directly," others are warning about alternator damage and proper current limiting. I'm planning to add a DC-to-DC charger eventually, but I'm confused about whether I can safely use the alternator to charge lithium batteries in the meantime.

What's the right way to handle alternator charging with lithium batteries? Should I disconnect the alternator feed completely until I get a proper charging system, or is there a safe way to make this work without turning my alternator into an expensive paperweight? …more

Ford 7.3 Godzilla Starter Relay Location & Fix

Finally found the starter relay for my 2022 RV's Ford 7.3 Godzilla engine that keeps staying engaged after startup — but will replacing it actually solve this? This has occurred multiple times and appears to be triggering crankshaft sensor errors, putting the vehicle into limp mode.

Diagnostics point to a faulty starter relay or incomplete grounding in the circuit. Need to locate the starter relay in the Ford 7.3 Godzilla to test and replace if necessary. Where exactly is this relay positioned, and what are the typical failure patterns for this specific issue on the 2022 model year? …more

RV Dash AC Blower Motor Not Working? Check These Hidden Fuses First

Last week I'm trying to decide between shelling out hundreds for an RV tech or tackling this myself after my F53 chassis motorhome's dash A/C blower motor completely died. I've checked all the obvious fuses in the main fuse panels, but nothing seems blown.

I discovered something crucial that might help others: Fleetwood added a hidden 25 amp fuse wire-tied above the emergency brake, not shown in standard Ford chassis diagrams. In my case, this was the culprit. As a temporary fix, I even ran a wire directly from my lighter plug with a switch to get some air movement.

I'm wondering if other RV owners might have similar hidden electrical components that aren't in standard chassis wiring documentation? Before taking it to a shop, I recommend carefully checking behind panels and tracing wires, especially looking near the dashboard area above the emergency brake for manufacturer-specific fuses. …more

How to Wire 12V DC RV Air Conditioner: Complete Dual Power Setup and Safety Guide

Around day three of running my 12V DC air conditioner, my RV's battery bank is getting absolutely demolished way faster than it should. I'm replacing my dead 110V AC unit with a 12V DC air conditioner that draws up to 52A on turbo mode. My plan uses an AC to DC 12V 125A 1500W power supply for shore power, and house batteries as backup power.

I'm particularly worried about my 20A changeover switch - is that going to handle the load safely? What about wire sizing and fusing? I know I need proper isolation between the two power sources but I'm scared I'm missing something critical. Can someone please review if this dual power approach is even safe, and what I absolutely need to fix before connecting anything? …more
