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 LP Gas Detector False Alarms: Complete Troubleshooting Guide

Already tried everything but my RV's LP gas detector has false alarms in the garage, keeps beeping at random times, AND won't reset properly. Even with the LP tank completely shut off, the alarm still goes off within hours. It's located in the bottom of the fridge cabinet.

I've checked everywhere for actual leaks - can't smell anything, and all my appliances still light immediately when I take the RV out. The detector seems fine outside but becomes a nightmare indoors. I'm wondering if it's the sensor going bad, poor placement, or if there are other things that can trigger these detectors besides actual propane leaks?

I really need a complete breakdown of what causes these false alarms and how to fix this issue once and for all. Should I be looking at replacing the detector entirely, or are there troubleshooting steps I'm missing? …more

Prevost vs Newell vs Foretravel vs King Aire: Which to Buy?

My wife and I are drowning in luxury coach research with our $500k-$1M budget and honestly have zero clue what separates Prevost, Newell, Foretravel, and King Aire for full-time living. Primary evaluation criteria include depreciation mitigation over 2-3 year ownership cycle and maintenance reliability metrics.

Specific units under consideration: 2017 Prevost Emerald at $850k with 60k miles, and 2016 Foretravel Realm K3 with low miles at approximately $400k. Also exploring 2021 King Aire and Newell models.

Seeking technical assessment comparing driving performance, interior quality, and reliability across Prevost, Foretravel K3/K4, Newell, and King Aire models. Concerned about potential maintenance requirements on older coaches, preferring newer models with resolved initial manufacturing issues.

Require detailed insights into value retention projections, drivetrain performance, and long-term operational dependability for these luxury coach manufacturers and specific model years. …more

RV Awning Won't Extend or Retract: Complete Troubleshooting & Repair Guide

This power awning manual says hold the extend button for 3 seconds, but mine's completely dead and won't budge no matter how long I hold it. When I hit the extend button, it moves out maybe 6-8 inches and then immediately retracts on its own. I have to turn the power switch off and back on each time to get even that little bit of movement.

I'm hesitant to keep forcing it since I don't want to burn out the motor or make whatever's wrong even worse. Could this be an electrical issue with low voltage, or maybe the tracks are too dirty? I've also heard about limit switches causing problems but I'm not sure how to check those safely.

What are the most common causes when an awning does this short extend-then-retract cycle? I want to start with the safest troubleshooting steps before calling a repair shop. …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

RV Electric Leveling Jacks Won't Extend - Fix Clicking Issue

Wondering if I should drop $800 on new electric leveling jacks or if this annoying clicking issue can actually be fixed first? The jacks were working perfectly fine on our last camping trip about two weeks ago, but now when I try to extend them, I can hear a distinct clicking sound coming from the controller panel, yet none of the jacks actually move or extend. The clicking happens consistently when I press the extend button, so it seems like the system is trying to respond, but something is preventing the actual mechanical operation.

I'm wondering what the most common causes are for this specific symptom - where you get the clicking from the controller but no actual jack movement. I'd like to understand the logical troubleshooting sequence, starting with the easiest things to check first before I dive into more complex diagnostics. The RV has been sitting plugged into shore power, but I know these systems can have multiple potential failure points including electrical, hydraulic, or control issues.

What should I be checking first, and what's the typical progression for diagnosing electric leveling jack problems that manifest with clicking sounds but no extension? …more

Ford V-10 Misfire Codes P0305 & P0307: Complete RV Engine Repair Guide for Motorhomes

Turned my compression tester on cylinders 5 and 7 and got 150 PSI readings, but I'm still pulling P0305 and P0307 misfire codes on my 2001 Ford E350 V-10. The engine runs smoothly overall, but the diagnostic codes are persistent.

I have replacement spark plugs and ignition coils available but want to ensure I'm following the proper troubleshooting sequence before investing time and effort. What is the recommended diagnostic approach for simultaneous misfires on cylinders 5 and 7?

Given that multiple cylinders are affected, should I prioritize certain components over others, or is there a systematic order that typically yields the most efficient resolution for this engine configuration? …more

Dometic RV Furnace Runs 10 Seconds Then Shuts Off - Complete Troubleshooting Guide

The YouTube tutorials I followed to fix my Dometic DFMD35111 furnace that runs 10 seconds then dies actually made it worse—now it won't even start! Every time I try to run it, the same thing happens - it fires up, runs for exactly 10 seconds, then just shuts off completely. This has been going on for weeks now and I'm getting desperate since the weather is getting colder.

I've been trying to troubleshoot this myself but honestly don't know where to start. I can hear the blower running and the unit seems to ignite initially, but then it just dies. Is this a common problem with these Dometic units? I'm really hoping this is something I can fix myself rather than having to call out an expensive repair tech.

What are the most likely culprits when a furnace runs for just 10 seconds then shuts down? I need to know what components to check first before I start taking things apart. …more

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

Onan 7000 Generator Low Voltage to Fuel Pump: Complete Repair Guide

Our Onan 7000 Marquis generator is hitting us with low voltage to the fuel pump for the third time this season and I'm done with guessing games. When I check the voltage at the fuel pump, I'm only getting 9V instead of 12V, and surprise surprise - it won't start. But here's the kicker - if I jump 12V directly to the pump, the thing fires right up and runs like a champ.

Obviously there's a voltage drop happening somewhere between the control board and the fuel pump, but I'm not sure where to start looking. Could be corroded connections, maybe the control board itself is going bad, or some wiring issue in the fuel pump circuit? Anyone dealt with this before and know the most common culprits? …more

Best OBD2 Scanner for Ford E450 V10 Motorhome: Top 3 Diagnostic Tools

Three different OBD2 scanners are showing 6 active codes on my 2015 Ford E450 V10 motorhome but every manual says this engine should only throw 2-3 max. I've been dealing with intermittent check engine lights and some transmission quirks, but my basic code reader just gives me generic codes that don't tell me much.

I keep hearing about tools like BlueDriver and some Ford-specific software, but I'm not sure what actually works well with these motorhome chassis. I need something that can give me real Ford-specific diagnostics, not just the basic OBD2 stuff. Has anyone found a scanner or diagnostic tool that actually works properly with the E450 V10 setup? I'm willing to learn something new if it means getting better diagnostic capability. …more

Norcold N7LX.3F Running Too Often: Complete Troubleshooting & Repair Guide

Standing in the RV supply store staring at replacement thermostats and control boards with no clue which one will actually stop my Norcold N7LX.3F from running constantly. It's been running way more frequently than it ever has before, and I can't figure out what's wrong. The cooling seems off too - items aren't staying as cold as they should be.

I've already checked the obvious stuff like making sure the vents aren't blocked and the unit is level, but something is definitely not right. The fridge just keeps cycling on and off constantly, which has me worried about both the power consumption and whether there's a bigger problem developing.

What should I be looking at to diagnose cooling efficiency issues? I really need to get this sorted before our next camping trip! …more

Banks Pedal Monster Ford F53 Motorhome Review: Does It Really Work?

Halfway through every camping season, I find myself second-guessing whether that Banks Pedal Monster I installed on my 2017 F53 chassis motorhome was worth it. After installation, I'm honestly not feeling much difference in performance, even in the most aggressive setting. The sales literature made it sound like it would dramatically improve acceleration and power.

I'm worried this expensive modification isn't actually doing anything meaningful for my heavy motorhome. Should I be feeling more power by now, or did I just throw money away? I'm starting to think maybe these throttle controllers don't actually work on big RVs like they claim to. Can someone help me understand what this thing is supposed to actually do versus what it can realistically deliver on an F53 chassis? …more
