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

RV DC Electrical System: Expert Guide to 12 Volt Systems

Opened my RV this morning to find the 12V system going haywire — lights dimming randomly, fans slowing down, and the inverter shutting off despite full batteries.

Specifically, I need to understand the fundamentals of RV batteries - different types, proper sizing, charging requirements, and maintenance. I'm also confused about DC wiring best practices, what gauge wire to use for different applications, how to properly route and protect circuits, and where fuses and breakers should go. Voltage monitoring is another area where I'm lost - I see all these battery monitors and don't know what I actually need or how to interpret the readings.

I'm also planning some system upgrades down the road like adding solar or upgrading to lithium batteries, so I'd love to understand how all these components work together and what I need to consider for future modifications. Is there a comprehensive resource that covers all aspects of RV DC electrical systems from batteries and wiring through monitoring and upgrades? …more

How to Remove Firefly RV Control Panel: Complete DIY Guide (2024)

Our 2019 Fleetwood Discovery LXE has a malfunctioning Firefly multiplex control panel that needs to be completely removed. I've been putting this off for months because I keep hearing horror stories about people cracking their panels or damaging the surrounding woodwork during removal.

I need to access the back of the unit for some electrical work, but I'm honestly terrified of breaking something expensive. The panel seems to be mounted flush with no obvious screws or clips visible from the front. I've searched everywhere but can't find a complete walkthrough that covers the preparation, actual removal process, and how to get everything back together properly.

Can someone please provide a detailed DIY guide that covers all the steps? I'm willing to take my time and do this right - I just need to know the proper technique so I don't end up with a broken control panel or damaged wall. …more

Sony VCB-62MH RV Camera Monitor Replacement: Complete Installation Guide for RV Coaches

Already cleared my Saturday schedule to swap out this Sony VCB-62MH RV camera monitor — what tools and prep work should I have ready beforehand? The Sony VCB-62MH rear view camera monitor in my 2008 Phaeton finally died, and of course Sony doesn't make them anymore. I've been searching everywhere for a replacement but everything I find is either way too big for the existing dash opening or doesn't work with the Sony cameras that are still perfectly fine.

I really don't want to replace the entire camera system - that would cost a fortune and the cameras work great. I just need the monitor replaced. Has anyone successfully found a workaround that reuses the existing Sony cameras and wiring? I'd love to keep the automatic switching feature for the side cameras when using turn signals if possible, but at this point I just need something that works and fits in the dash opening. …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

Balance Beads with Internal TPMS Sensors - Real Experience

Since it's 2 AM and I need to hit the road at dawn, I'm desperately trying to figure out if balance beads will interfere with my RV's internal TPMS sensors. I keep reading about how great balance beads are for eliminating wheel vibration, but I'm terrified of damaging those expensive TPMS sensors inside the wheels.

What if the beads hit the sensors and break them? Or interfere with the signal? I can't afford to replace TPMS sensors if something goes wrong. Has anyone actually done this successfully, and are there special precautions I need to take with bead size or how they're installed? I need to know this is safe before I risk it. …more

50 Amp RV Inverter Charger Replacement: Complete Installation Guide 20

Finally moved into an RV with a 20-year-old Tradewinds inverter/charger unit that's completely dead and I have absolutely no idea how to replace it. The repair shop is offering a used Magnum MS2812 (2800VA) for $700 installed, but I'm concerned about its actual charging capacity versus my requirements.

My RV is wired for 50A shore power service, and I need an inverter/charger that can handle the full charging load. The shop claims the MS2812 will work, but the specifications seem to indicate it's only a 30A charger unit. Are there any legitimate 50A inverter/charger options available under $1000, or should I be looking at different manufacturers like Progressive Dynamics or Aims for this price range? …more

RV Generator Size Calculator: Solar vs Gas Generator Power Needs for Your Camper

Woke up to my Aliner classic's power system working perfectly in 60°F weather, but now that it's 85°F outside I'm drowning in solar versus gas generator confusion. Coming from a Rialta with a built-in generator where I just added some solar panels, I'm now starting from scratch with just one 88Ah lead acid battery and need to figure out the most practical setup for my boondocking needs.

My power requirements are pretty straightforward - laptop, house lights, furnace for overnight heating, and the occasional use of my 1800-watt toaster oven which is really the main power challenge. In my previous RV, I had 160Ah of lead acid batteries with a 100W solar panel that handled everything except the toaster oven, which required firing up the generator. I'm considering adding 200W of solar panels to this setup.

Here's where I'm getting confused: I've been looking at 2000-2500 watt generators with minimum 1900 running watts, but I heard you shouldn't run more than 80% of the running watts capacity, which would mean I need about 2300 running watts just to safely operate my 1800W toaster oven. Is that calculation correct? Alternatively, I'm wondering if I could skip the generator entirely and run the toaster oven off a large battery bank with a proper inverter - but I have no idea how much battery capacity that would require or if it's even practical. What's the most cost-effective approach for someone who primarily needs reliable power for essential loads but occasionally wants to use higher-wattage cooking appliances? …more

Southwire EMS Built-in vs External Surge Protector: Do You Need Both?

Opened my 2022 Holiday Rambler 38N DP and discovered it's eating through surge protectors way faster than normal, despite having the built-in Southwire system. Dealer says I might not need an external surge protector like a Watchdog since it's already built in.

Does a built-in Southwire surge guard provide the same protection as a standalone EMS unit? Should I still install an external surge protector or is the built-in system sufficient? Want to make sure I have proper protection without buying unnecessary equipment. …more

12V RV Refrigerator Power and Battery Charging While Towing: Complete

Woke up this morning realizing our new fifth wheel has a 12V refrigerator instead of propane, and we're picking it up next week for our big family camping trip. Over the years with my other RVs, I've always been confident that the house batteries would charge while driving since they're connected to the tow vehicle's charging system through the umbilical cord.

However, I keep reading concerning posts online about 12V refrigerators not staying cold during travel days because they supposedly drain the house batteries faster than the tow vehicle can charge them. This has me puzzled because I've never had charging issues while towing before. If the 12V fridge is running off the same house battery system that gets charged by my truck while driving, shouldn't the charging system be able to keep up with the fridge's power demands?

I'm trying to understand the actual power requirements of these 12V fridges and whether my tow vehicle's charging system through the 7-way connector will realistically be able to maintain the batteries and keep the fridge running properly during long travel days. What kind of amperage draw should I expect from a typical RV 12V refrigerator, and how can I verify that my charging system is working adequately while towing? …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
