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

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

1999 F53 V10 Oil in Coolant: Complete Head Gasket Diagnosis & Repair Guide

Called three dealerships about warranty coverage for oil contamination in my 1999 Ford F53 V10's coolant system — before I tackle this head gasket nightmare myself. The unit overheated after the oil level dropped significantly, though it still starts and runs without throwing any codes.

Based on the symptoms, I suspect a blown head gasket, but I want to perform proper diagnostic testing before committing to a major repair. What specific diagnostic procedures should I run to confirm whether this is actually a head gasket failure versus other potential causes like a cracked head or block issue?

Looking for a systematic approach to pinpoint the exact problem before I start tearing into this engine. …more

Coleman Mach AC Fuse Blows With Battery On - Rockwood Fix

Found out the hard way that the previous owner of my 2019 Rockwood Minilite 2509s left me with a Coleman Mach AC that blows fuses instantly when I flip on the battery. The AC fuse blows instantly when I turn on the battery disconnect, before the AC is even activated. The fuse literally blows before it's completely seated in the panel.

This began two weeks ago without warning - the system had been functioning normally prior to this. Initial fuse replacement provided temporary operation, but the problem returned on the next trip with the fuse already blown upon arrival.

Given the immediate fuse failure with just battery power connected, what type of electrical fault would cause this symptom pattern in a Coleman Mach unit, and what's the most likely location of the problem in the AC circuit? …more

Dometic R31 Stove Review + Gas Pressure Test Guide

Walked into my RV this morning to find my Dometic R31 stove flames randomly dying again - probably a dumb question, but is this normal? I've been looking at the Dometic R31 as a potential replacement, but I want to make sure I'm making the right choice before spending the money.

What's really concerning me is this gas pressure test mentioned in the installation manual. It talks about connecting some kind of gauge to a test port on the regulator, but doesn't specify what type of gauge or what pressure readings I should expect. I'm pretty handy with basic repairs, but gas systems make me nervous and I want to do this safely. Has anyone actually done this test, and is the R31 reliable enough to justify the upgrade from my problematic Wedgewood? …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

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
Best Oil Filter for Ford V10 RV Engine - Complete Guide

Best Oil Filter for Ford V10 RV Engine - Complete Guide

After walking out to my RV this morning, I spotted my Ford V10's oil filter looking suspiciously ready for replacement, but I'm completely lost on which one won't break the bank. I keep hearing conflicting advice about which oil filter to run.

Everyone seems to swear by different brands - some say Wix 51348 is the sweet spot, others mention NAPA Gold 1348 (are these the same thing?), and then there's the Mobil 1 M1-210A crowd. At Rock Auto, I noticed Fram filters like TG2 ($6.43), XG2 ($9.50), and HP16 ($12.82), plus a Mobil 1 M1210A at $8.14.

What's the real deal here? Is there actually a 'best' filter for the V10, or am I overthinking this whole thing? I'm also considering adding a bypass oil filter. I just want something reliable that won't break the bank every oil change, especially since this rig sees a lot of highway miles. Is a $23 Amsoil filter really worth three times the price of a Wix? Any recommendations from fellow V10 survivors? …more

Onan 5500 Generator Tune-Up Guide: Best Aftermarket Parts & Filters 20

Before my last camping trip when I tried to order replacement parts, I discovered that finding genuine OEM components for my Onan 5500 generator has become nearly impossible. The Cummins website has been showing most tune-up components as out of stock for months now, and when I do find supposedly "official" Onan oil filters online, many retailers are substituting generic filters that may not meet the same specifications.

I've been researching alternatives and I'm particularly concerned about getting the right oil filter and spark plugs. For the oil filter, I've seen conflicting information about whether aftermarket options like Wix filters are truly compatible - some sources mention the 57398 but I've read mixed reviews about fitment issues. For spark plugs, my current ones are NGK BPR4EY, and I've heard the NGK 3432 might be equivalent, but I want to make sure before ordering.

I'm also planning to stick with zinc-containing oil like Rotella T6 15w40 since I know air-cooled engines need the extra protection, but I'd love confirmation that I'm on the right track with quality aftermarket parts that won't compromise my generator's performance. What specific part numbers and brands would you recommend for a reliable tune-up when OEM parts aren't available? …more

Norcold RV Refrigerator Fire Hazard: Complete Prevention Guide & Safety Tips

Standing in my flooded RV after last week's torrential downpour, I'm realizing my Norcold double door refrigerator might be one electrical surge away from turning this whole rig into a bonfire. I've discovered a concerning burn mark that suggests serious heat distribution issues, particularly around the chimney and heat diverter placement.

I'm trying to figure out if this is one of those real risks from the previous class action lawsuit or just an RV urban legend. After the factory modifications following the lawsuit, which installed a thermal overheat switch, I'm still worried about the fundamental design - specifically how the heat diverter seems to direct heat toward the cabinet wall.

What exactly causes these fire risks, and more importantly, what can I actually DO about it? The fix seems to involve removing the fridge and installing heat protection on the cabinet wall. I've heard whispers about recalls and some prevention methods, but I want concrete steps to ensure my RV doesn't become a potential fire hazard.

Any guidance on real prevention steps would be amazing - I'd rather not explain to my insurance company why my vacation home spontaneously combusted! …more

Ford F53 RV Power Steering Flush: Complete DIY Guide (1995-2022)

Looked under the hood of my newly purchased RV and discovered the previous owner left the F53's external power steering reservoir with three return lines in absolutely terrible condition. They all clamp onto separate fittings on the bottom of the reservoir.

I'm trying to figure out the right way to flush this system. Should I be disconnecting each return line one at a time from the reservoir and doing them separately? And if I do that, do I need to cap off the reservoir fitting where each line was connected so it doesn't just dump fluid everywhere when I'm working on the other components?

Or is there a simpler approach that'll get all three components clean without all the hassle of disconnecting lines? …more
