Results for "pulsing"

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

Noticed my RV water pump keeps pulsing and cycling on its own even when no faucets are running - is this dangerous with kids around? The water pump keeps turning on and off rapidly - like every few seconds - even when I don't have any faucets or anything running. It's doing this pulsing thing constantly.

I've heard someone mention something about an accumulator tank, but I'm not really sure what that is or how to check it. Could there be other things causing this too? I'd really appreciate some guidance on what might be wrong and where I should start looking. This is all pretty overwhelming as a beginner! …more

Standing in front of a 2015 Winnebago Vista V-10 that pulses during acceleration — should I walk away or is this worth buying and fixing? My 2015 Winnebago Vista with the F53 chassis and V-10 engine developed this awful pulsing problem during acceleration after driving through mountain passes in Montana. It feels like the engine is cutting out then surging back - not rough idle or jerking, just this frustrating loss of power that comes and goes.

I've tried everything I can think of - checked vacuum hoses, inspected connections, even tried fuel additives thinking it was bad gas. The diagnostic scan only showed one code: "Fault received from External Node" which apparently relates to the instrument cluster, but the tech had no clue what that actually means or if it's connected to my acceleration problems.

What could be causing this pulsing issue on a V-10 after mountain driving? I'm hoping someone has seen this before because I'm running out of ideas and really need to get this figured out before my next trip. …more

Pulled every trick in the book — replaced all five driver side ignition coils, swapped the PCM, checked every connection — my 1999 Itasca Sunflyer V10 still throws codes P0356, P0357, P0358, P0359, P0360. Running on 5 cylinders only.

Tested +12v at each coil connector - all good. Tested for ground pulse during cranking - nothing on drivers side, but passenger side coils pulse normally. No visible wiring damage found.

Does this testing confirm PCM failure in the ground switching circuit? Seems unlikely all 5 coils failed simultaneously. …more

Noticed my 2025 Jayco Precept 29V windshield wiper motor completely died after I followed a YouTube repair tutorial that somehow made everything worse. The system appears to be integrated with the Ford chassis electrical components, but I need to systematically troubleshoot the root cause before pursuing warranty repairs.

What are the primary failure points in the Jayco Precept wiper system, and what diagnostic sequence should I follow? I need to verify whether this is a fuse issue, switch malfunction, motor failure, or mechanical linkage problem. The symptoms suggest electrical failure, but I want to eliminate all possibilities methodically.

Specifically looking for guidance on the Ford chassis integration and most common failure modes for this model's wiper system. …more
