ECM Low Battery Warning RV: Complete Diagnosis & Fix Guide

During a family trip, my 2005 Fleetwood Discovery 39S threw code 168-1 for low ECM battery voltage and went into full shutdown mode—is this dangerous with kids onboard? Engine cut out, transmission selector went dark, ABS warnings everywhere - the whole nine yards. Scared the heck out of me when it happened on the interstate!

I'm seeing this seems to be a thing with these diesel pushers, but I'm drowning in conflicting info online. Some say it's the chassis battery, others blame alternator issues, and I've even seen posts about ECM power supply problems on the Caterpillar engines. What's the actual step-by-step process to track this down? And more importantly, how do I fix it so it doesn't leave me stranded again? Really need a complete walkthrough of what causes this code and the proper repair approach. …more

RV Storage on Gravel: Preventing Weed and Moisture Issues

Nobody warned me that buying a house with RV storage meant inheriting the previous owner's 13-year-old weedy, muddy gravel disaster. While considering this location's storage options, I want to mitigate potential issues with weed growth and moisture retention under the RV.

I'm seeking advice on effective strategies for storing on a gravel surface that shows significant weed penetration and moisture retention. Initial ideas include pre-treatment herbicide application and installing a protective barrier, but I want input from experienced RV owners.

My primary concerns are preventing undercarriage damage and managing moisture/vegetation growth. I plan to spray weed killer beforehand and potentially lay down a weed barrier, pending facility approval. What techniques or materials do you recommend to protect my RV during storage? …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

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

Ford F53 7.5L RV Won't Start: Fuel Pump Relay Voltage Drop Fix

Woke up to my 1996 Ford F53 7.5L motorhome eating through my patience and wallet with this no-start issue that keeps coming back. It cranks strong but absolutely will not start, and I've been chasing this problem for weeks now. The engine ran fine for about 3-4 minutes one day, then just died and hasn't started since.

I've already done quite a bit of diagnostic work:
- Replaced PCM and distributor
- Fuel pump works when powered directly
- Battery is fully charged
- Checked fuses and relays
- PCM relay voltage drops from 12.2V to 9.3V with key on
- Fuel pump relay only shows 3.3V at pin 86 (should be 12V)
- Inertia switch tested at 1.7V at connector
- ANL 178 fusible link fluctuates between 0.3-0.6V

The engine will only start with starter fluid when the SPOUT is removed. I'm getting only 5.5V at the fuel pump connector.

Has anyone dealt with this specific issue on an F53 chassis? I really need to get this RV back on the road and I'm running out of ideas! …more

Monaco Diplomat Rear Air Suspension Won't Dump Fully - Troubleshooting Guide

Last week my 2006 Monaco Diplomat's rear air bags started refusing to dump all the way down when I hit the air dump before leveling. The front dumps fine, but the back stays partially inflated.

I'm still pretty new to RV maintenance and not sure where to start troubleshooting this. Should I be hearing air escaping when I activate the dump? What are the most common causes when rear air bags won't dump completely? Any guidance on what to check would be really appreciated! …more

Remote RV Diesel Fueling: Complete Guide for Campground Fuel Strategies

Last night at 11 PM I'm staring at my diesel RV's fuel gauge showing nearly empty — need to figure out remote campground fuel strategies before we head out this morning. With a 5 gallon Harbor Freight stick transfer pump, I've been able to add fuel when truck stops aren't convenient, but I'm concerned about static electricity risks.

My current setup involves using the pump to transfer diesel with the fuel can on a camping table, since my RV's fuel inlet is located under a slide. I pumped 10 gallons successfully, but I'm wondering about the safety of this method.

I know there are static electricity concerns when transferring fuel, and I'm curious about the specific risks with diesel. How safe is it to transfer fuel when the can isn't directly grounded to concrete? Are there best practices I should follow when manually adding diesel in remote locations? …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

How to Find Reliable RV Repair Shops: Expert Tips & Red Flags to Watch Out For

About every summer my 2004 Adventurer runs like a dream until temps hit 85°F, then it breaks down constantly and no shop can figure out why. The main slide out has been acting up with the HWH hydraulic system, and I honestly don't know enough to fix it myself.

I'm worried about getting taken advantage of since I don't really know what questions to ask or what warning signs to watch out for. I've heard horror stories about people paying huge bills for shoddy work. What's the best way to research and find a reliable shop? Are there specific things I should ask them before I commit to having work done?

Any guidance would be really appreciated - I just want to make sure I'm being smart about this and not walking into a bad situation. …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

RV AC Freezing Up? Fix Ice on Coils in 5 Steps

Turned on my RV's AC as a total newbie and watched it run perfectly for an hour before becoming a frozen disaster that won't cool. I can literally see ice building up on the coils, and then it's game over until everything thaws out.

This has happened a few times now and I'm getting tired of sitting in a hot RV waiting for the thing to defrost. What actually causes AC units to freeze up like this? And more importantly, how do I stop it from happening again? I'm guessing it's something simple I'm missing, but I'd rather fix it right than keep dealing with this cycle. …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

Dometic 12V Refrigerator Not Cooling on Battery Power - Complete Troubleshooting Guide

Staring at my Dometic DMC compressor refrigerator that runs perfectly on 12V DC when it's cool but stops cooling completely once temperatures hit 85°F or higher. The unit works perfectly when I'm plugged into shore power at campgrounds - everything stays cold and the freezer compartment keeps items frozen solid. However, when I'm boondocking and running solely on my RV's battery bank, the performance drops significantly. The refrigerator struggles to maintain proper temperatures, and the freezer can't keep things frozen.

I have a relatively new battery setup with what should be adequate capacity for my power needs. The batteries test fine with a multimeter when the refrigerator isn't running, but I'm wondering if there's something I'm missing about power requirements or electrical connections. I've heard that 12V compressor refrigerators can be pretty demanding on battery systems, but I'm not sure what specific issues to look for.

What are the most common causes when a 12V Dometic compressor refrigerator works fine on shore power but fails to cool properly when running on batteries? I want to troubleshoot this systematically before calling in a technician. …more

RV Slide Out Won't Retract: Motor Runs But Won't Move - Fix

Planning to use the same motor running trick that saved my old Winnebago's slide out, but this new rig's slide won't budge at all. It extended just fine this morning, but now when I try to bring it back in, the motor sounds like it's working but the slide isn't budging at all. I can hear it running but zero movement.

I'm trying to figure out if this is a hydraulic problem or if I've got a cable system that's gone haywire. Could it be something simple like low fluid, or am I looking at broken cables? Don't want to mess around with it too much without knowing what I'm dealing with first. …more
