Rodent wire damage also possible or motor or switch fail

Daveo37 · 06-15-2022, 08:45 AM

So here is the latest..... all fuses in the motorhome checked good. 3 breakers in the battery compartment (50, 80, 100) all had good continuity, but no voltage. The solenoid (I assume thats what it is) has no continuity and no voltage. When checking the voltage of the breakers, do i need someone operating the system (ie: steps or slide switch) to get voltage to the breakers? Doesn't looks like I need to do that since the breakers are wired directly from the battery. Battery checked good at 12+volts. No voltage to the slide switch wires, slide switch continuity checked good.
PS Cant get photos to upload..... says I have to create a URL for them

Last- first; Photos you need to Upload to FILES this website under your profile; (THEN you can attach to Post; 2) Solenoid MAY be a LATCHING SOLENOID= BATTERY DISCONNECT; operates by a ROCKER SWITCH, ONLY REQUIRES MOMENTARY POWER to COIL if latching; THE ROCKER SWITCH gives momentary REVERSE POLARITY to turn back OFF. Lookup LATCHING SOLENOID ON AMAZON/ EBAY / GOOGLE PICTURES, AND IF YOURS HAS THE EXTRA SMALL CYLINDER ON TOP or bottom(for lock mechanism) = MOST LIKELY LATCHING (vs Starter or continuous) Good Luck

p.s. so about 5-diff types of solenoids/ relays= 1) Normal ON/OFF; 2) SWITCHING (position a or B); 3) STARTER,= SHORT OPERATION/ HIGH CURRENT; 4) CONTINUOUS DUTY; high/low current ratings; 5) LATCHING (LOOK UP TROMBETTA, their webpage explains a lot on latching solenoids.

The POLARITY REVERSE COMES FORM TEH rocker switch (swaps BOTH wires to solenoid)

Not sure about the situation on older coaches. But ... you may be able to have all the indications that the Parking Brake and Ignition are ON. But are those signals actually getting to where they are needed to activate the slide ?

I just went through this on our RV. The Ignition ON signal (+12V) was not being received by the control board. The Parking Brake ON is a (-12V) signal and that worked fine. In our system.

I can't really help too much beyond just offering the suggestion. And to me the symptom of low DCV would be suggesting that the power is not being applied to where it is needed.

How all that happens is determined by your specific application.

1st, let me thank everyone for their help and suggestions with my slide out not working. I really appreciate your expertise and for the time you took to reply to my problem.
So now here is the latest: I thought about my slide out problem all day at work yesterday because this weekend is our maiden voyage with our new/used motorhome. When I got home from work i headed straight to the motorhome because I was thinking that I had forgot to turn the battery power switch ON before I tested all the fuses and breakers. If I had forgot to turn the battery switch ON then of course I would get 0 voltage (or so I think). I immediately checked the battery power switch and I was wrong, I had turned it ON and it was still on but I was not connected to shore power as I had unplugged that before I did my testing and I was testing just with battery power. So there I am scratching my head as I look and see my switch wires dangle out of the wall and my volt meter sitting on the arm of the couch. The wife walks in the motorhome and starts some small talk so just for something to do while she had me cornered, I picked up the volt meter and for the 20th time I checked the voltage of the slide switch wires. The IN and OUT wires read 12V. WHAT? I did a double take and tested them again... 12V! I put the switch back together and VOILA... my slide worked! WTH? The only thing I did that I never mentioned was that I cleaned some corrosion off of the positive side of the battery terminals.. Hopefully that was the fix and this isnt just a fluke thing and Im stuck with the slide out not working this weekend. Again, thanks gang for your help... safe travels

Glad to hear that you got it resolved. Electrical issues can be tricky. I assume from the lack of subsequent posts that you no longer had the issue (fingers crossed).

I probably shouldn't be replying since I know nothing about Gulf Streams or Lippert slides, but I've always been under the impression that it's best to operate slides with the engine running to maximize your power and minimize drawing down your house batteries.

BCam, Engine ON/OFF to operate slide varies by Manufacturer, slide type and maybe by Year. E.g. My slide, a hydraulic DEWALD, requires IGN=OFF or slide inop. Locked out by little cube relays. Finally verified by COACH OWNER MANUAL TEXT from my yr. 2000 MODEL.. Maybe child safety while traveling?]

Interesting. I think this is commonly accomplished with a parking brake interlock.

Unless you're prevented from doing so, I don't see a downside of having your engine running. It's not going to overpower your slide motor or anything. The slide motors won't draw any more amps than they need. The same goes for having your generator on or being on shore power when operating your slides.

After you've checked all the suggestions mentioned above , check the wiring terminations at the motor .

RV Slides are not submarine hatches . Rain can and will get into the spaces around the slide .

Our daughter and son in-law had a slide that stopped working . It worked fine 2 days earlier when they set up for the weekend , then when breaking camp the slide refused to retract .

Found a positive wire terminal that had corroded and rusted through . Replaced the wire terminal , a 5¢ part and all's well .
