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

RV Infotainment System Update Guide: Step-by-Step Safety Instructions

Three weeks ago my 2023 Aspire's infotainment system occasionally wouldn't recognize the update USB, but now it just blinks endlessly without doing anything.

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 Lithium Battery Not Charging: Complete BMS Reset & Troubleshooting

According to the manual my RV lithium battery should charge normally after BMS protection kicks in, but mine's been sitting completely dead for hours. My Battle Born battery is showing 20% charge, but it's not taking any power when I plug into shore power or when my solar panels should be charging it.

I've been reading about BMS protection modes but I'm not really sure what that means or how to deal with it. Is there a way to reset the BMS system? I'm a bit out of my depth here and would really appreciate some guidance on troubleshooting this before I have to call for expensive repairs. …more

Ford E450 Inertia Switch Location Guide - Find Your RV's Fuel Cutoff Reset Point

Every Ford E450 I've worked on had the inertia switch behind the driver's panel — but my 2011 Freedom Elite 32r has it hidden somewhere completely different. The engine is experiencing what appears to be fuel delivery issues after a minor fender bender, and I suspect the inertia switch may have been triggered and needs to be reset.

I've already done extensive searching in the typical locations - removed both driver and passenger side kick panels completely, pulled out the glove box, and even partially disassembled sections of the dashboard. Despite checking all these common spots where Ford usually places these switches, I'm coming up empty-handed.

Could the switch be integrated into another component on this particular year and model? Are there any alternative locations specific to the E450 chassis or Freedom Elite configuration that I should be checking? I'm also wondering if some models of this year might not have a traditional standalone inertia switch at all. …more

RV Battery Disconnect Switch Guide: When to Use, What Loses Power & Staying Safe

Wondering if I can skip the $400 shop diagnosis for my electrical issues and just figure out this battery disconnect switch myself, even though I'm getting conflicting advice.

Specifically, I'm concerned about what happens to things like my LP gas detector, carbon monoxide alarm, and refrigerator when I disconnect the battery. Will I lose all my radio presets and clock settings? Are there certain situations where I absolutely shouldn't use the disconnect switch?

I want to use it for storage to prevent battery drain, but I'm also wondering about daily use scenarios. What are the best practices to avoid any problems or safety issues? I really don't want to mess anything up or put my family at risk. …more

How to Fix RV Rear Brake Lights and Hazards Not Working - Common Grounds & Connections

Spent months planning our cross-country trip leaving next week and my RV's rear brake lights and hazards just completely stopped working. My 1998 National Tropical (on a '97 Ford F53 chassis with the trusty 460 V8) has decided to get creative with its lighting situation. The rear brake lights and 4-way hazards have completely given up the ghost - nothing, nada, zero response from the back end. But plot twist: the turn signals work just fine back there, and everything up front (brake lights, hazards, turns) is working perfectly.

I'm scratching my head because if it was a fuse issue, wouldn't ALL the lights be affected? The fact that some work and others don't has me thinking it's something more specific. Any ideas where I should start poking around to solve this electrical mystery? …more
Fix Renogy Lithium Battery Charge Percent Differences

Fix Renogy Lithium Battery Charge Percent Differences

Nobody has $200+ laying around for a service call — is there a DIY fix for Renogy lithium batteries showing wildly different charge percentages? About a year ago I installed 3 12v Renogy lithium batteries with a Renogy One Core control panel in my RV. Everything worked beautifully at first - the batteries were supposed to communicate with each other to keep all cells balanced, which is critical for lithium battery health.

Recently though, I've noticed the charge percentages are diverging by as much as 10% between batteries. Even worse, my One Core display keeps going blank and won't show charge percentages until I restart it. I've been through the manuals multiple times but can't find anything about troubleshooting charge percent differences or how to check for software updates on either the batteries or the control panel.

I know this communication/balancing issue could lead to serious problems if not addressed. Has anyone dealt with this before? I'm hoping there's a solution that doesn't involve replacing everything after just one year of use. …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

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

HWH Levelers Flashing Blue Light: Complete Battery Reset & Troubleshooting Guide

Opened three different browser tabs trying to figure out why my HWH levelers are flashing blue — neighbor says dead batteries, dealer claims sensor issue, YouTube insists wiring problem. The blue light keeps flashing and the jacks won't respond at all - they won't go up or down. The only thing that seems to work is disconnecting the house battery for about 15 minutes until all the panel lights go dark, then reconnecting it.

I'm worried this might be a sign of something serious going wrong with the electrical system or the levelers themselves. Could this indicate low voltage issues or bad connections that might be unsafe? I really don't want to damage anything expensive or put my family at risk. What should I be checking, and is this something I need to call HWH about immediately? …more

RVLock Atlas Keyless Entry Installation Guide - Quick 15-Minute RV Door Fix

Between the metallic grinding when I turn the key and the ominous clicking from inside my 2016 Bounder's door mechanism, I'm ready to upgrade to an RVLock Atlas keyless system. It's specifically designed for RV doors and seems to be the only keyless lock that fits my model. The installation was incredibly quick - it took just ten minutes and required only a small Phillips screwdriver and a jeweller's screwdriver to press the reset button during programming. The Atlas comes with a QR code linking to a helpful how-to video. Just be aware it's a significant investment at $299. While pricey, the straightforward installation makes it appealing for a DIY RV owner. …more

RV Red Fault Light No Power: How to Fix Partial Electrical Outage

Tried rewiring my RV's electrical system yesterday but something still doesn't seem right — red fault light is on and half my outlets have no power. My Class A has this red fault light glaring at me from the power panel, but it's not a total blackout situation. AC is running fine (thank goodness!), but my fridge, microwave, and some outlets decided to take a vacation.

I already tried the usual suspects - reset every GFCI I could find inside and messed with the main power cord panel outside where shore power comes in. Still got that annoying red light mocking me.

This partial power thing is driving me nuts. What should I be checking next to get everything back online? …more

How to Fix RV Propane Detector False Alarms: Complete Troubleshooting

Every YouTube tutorial I followed to fix my RV's LP gas detector false alarms only made it beep more frequently at night. The detector appears to be responding to non-gas triggers, but I need to systematically determine whether this indicates sensor degradation, environmental interference, or if there's an actual safety concern I'm missing. What are the primary causes of false positive readings in RV propane detection systems, and what diagnostic steps should I follow to differentiate between legitimate equipment failure versus actual gas leak detection? …more
