Mostly electrical questions

I bought a used 2017 Windsport 29M. Ford F53 chassis.

Still shaking out just how everything works and nothing too serious going on.

I try and find answers in Thor and component item manuals. Pretty frustrating as everything is 'If your model is equipped' etc.

1: while driving I can't lower the sun shade. Key has to be off to lower it. Will go up no problem. There is a tiny momentary switch hanging down about 6 inches by the left end of the shade roll (like a valet switch on an alarm). Don't know what it is for or if related.

2. My model doesn't have any shades on the cab side windows. Is there after markets available I could add?

3. How can I tell if this F53 chassis has an oil change nag system? The Chevy system on my previous C class was surprisingly accurate. With cost of gas I think it is going to be more of a calendar change than mileage, but just wondering.

4. My coach battery disconnect relay seems bad. It clicks but doesn't disconnect. Still have some tests to try but the relay is quite cheap if thats it.

Has anybody just replaced this with a manual switch? The relay is mounted under the master bed on the front panel of the bed. It would be easy to put a manual rotary disconnect switch in the same location.

I believe this is the replacement relay

And this is the manual switch I would use instead

Thoughts? And Thanks!

First, Welcome to the forum.

The front window shade on most coaches will come down about a foot to serve as a sun visor.

Most rigs had shades, blinds, or curtains on the drivers and passengers windows.

No oil change nag system on that model year F53.

I will not comment on the coach disconnect because I am not. there troubleshooting with a multimeter. I will allow you to make your own WAG on that item.

Again, welcome to the forum.

1 - By design for safety. The little hanging switch is for calibrating the stop locations.

3 - It does, goes off at 5000 miles.

4 - That's unusual. Usually they go bad by clicking and NOT making contact. Yes you can change it to that manual disconnect but realize if you are connected to shore power all the DC loads will still operate even if the battery disconnect is open - powered by the converter.

Thanks for your welcome & comments.

Yes I feel like the sun shade should come down. I guess I'lll have to tear it apart it seems fishy that a switch is already hanging out.

I have side curtains for privacy on the sides but nothing for side sun shades. I think pull downs on each side would be perfect, but I can't rind anything in the RV accessories market for that

1- you need to reset the sun shade for driving (shade will only go down so far) and when parked (shade will go all the way down)

2-no oil change monitor.

3-shades for front windows. I got mine from Steve's Blinds

4-i added a battery cut off switch in the battery compartment. I never use the factory use/store switch

Thanks the blinds look great.

How do I reset the front shade for driving? It won't go down at all while driving. It works fine when parked

I have been leaving it down a foot all the time before I break camp so it is there if I get direct sun in my face.

By design the front shade will not go completely down with engine running. Itís a safety thing. Donít mess with it. Itís working the way itís supposed to. Why would you want it all the way down while driving?

Looks like your shades donít fit full width. I think your windows are like mine. Wider at bottom than at top. Looks like you installed reflective stuff on the top section. Velcro. What is behind the rest? Which product did you get from Steveís?

Sorry for the mis understanding.

It does not come down at all when driving. In other words it is not working like it is supposed to.

It is actually dangerous the way it is (no sun shade at all)

When I said I leave it down before I drive, I meant at sun shade level, not all the way down.

It will go up while driving it just will not come down at all. I just want to be able to use as a sun shade when needed, as apparently it was designed.

Where can I find the calibration instructions? I can't get the little switch to do anything.

Re shore power: Isn't that same whether it is manual switch or relay? Your comment makes me wonder if this will effect coach battery charging (alternator, shore, generator). Does the latching relay get released if external power is supplied or does it still have to be reset (use mode) to charge? Or is charging done with battery isolators and/or diodes?

Programming sun shade instructions worked perfect! THANK YOU

Took several tries but eventually I got it

They really need a sequence to clear all programming before start, or exit program if you screw up, but really it was fine.
