Got coach positioned in front of shop so i could operate forklift on my concrete pad but couldnt pull forward enough , so backed out got the old backhoe and cleared some blow sand out of the way and cut back one of my creosote bushes. My pallet on the fork lift is 12 feet long and cut in down to under 4 feet deep. Covered with some old carpet got positioned and working at getting slide to extend. Ive never operated it with the HWH controls and its seems to be headstrong at resisting. Placing the slide control key to on the vacuum retracts bladder and after about 40 seconds the yellow light illuminates. Press extend button and nothing happens. Indicating about 9 inches of vacuum on old bladder. Pump never runs and locks still show engaged.

The 3A fuse led isn't lit...does that mean there's a fuse out?  Is the coach level on the HWH pad?

Don't know. Or location of this three amp fuse?
 It is in level and key on.
Just had lunch and was going to open HWH box and check fuses. If I dont find any will try override position.

Inside HWH all the lock solenoids are not indicated powered up or showing that there powered up?
Edit they do power up during operation

Found this tidbit:

"IF the electronic box is double stacked there is another fuse behind it on the motherboard.. Blew a 3amp fuse o my slide board that was double stacked so I couldn't find the issue.. after a service truck came out he was walked to it by HWH."

in this thread:  Stuck in Colorado Springs with HWH problems

Do you have the coach manual/schematics?  See if this one helps.  There are 2 or 3 "3-amp" fuses mentioned:  http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwiqkeamnOf1AhUzD0QIHWnNDcwQFnoECCAQAQ&url=https%3A%2F%2Fwww.hwhcorp.com%2Fml26139.pdf&usg=AOvVaw2BnXX0Phyo6hrd_LoYw19S

I see you have the pro helping...that's like cheating!  :)  Great to see you got it out.  Did you get it to move? If so, what was it?

Yes I was four minutes from calling him when he pulled in the drive way. Never did find the fuse but isolated to the power supplied to the pump solenoid. Tomorrow is another day to hunt for it. Jim operated it and I hot wired the pump motor and it unlocked lock pins and once pulled drove slide out. Coach level , ignition on. The failing bladder would actually inflate and deflate and enable the vacuum interlock system. Not a big hole but once we got the slide out upon further investigation the bladder would tear with little effort. New and improved design should deliver another twenty years of service. Will need to resolve power problem but for now have enough work to keep me busy. Also figured out how to raise back of slide .050 by changing shims on actuator. All I lack is finishing. Long day. Thank you Jim (Fourdayoff) for helping me out again.

Wow! Scott and I were able to get his slide out of the coach. Allot of inspection and contemplating but it's just nuts and bolts, lots of them. Not for the faint of heart but as you know by now Scott is a trooper, he will tackle anything. It's a privilege to help and learn from him. Now a couple of days to strip out the old bladder and install the new. Then the fun starts again reinstalling the slide.

Question about the last photo in reply #40.  The limit switch status indicator panel.  is this component installed in the coach and if so where is it located?

About two feet forward of the HWH computer coach left, storage compartment on the ceiling. With slide extended all of the opposing leds illuminated in yellow. Still need to figure out why the 3amp fuse does not illuminate and we're this fuse is located. The diagram inside the computer with all the fuses doesn't describe a 3 amp fuse. The fuses and circuits are active during operation of the unlock, extent, retract lock operation.
When the control panel upstairs gets the yellow vacuum ready light and you operate the extend or retract the red light comes on to indicate that the pump is running but is is not. I'm hoping the two are a common issue

Might I suggest a set of really good ear plugs for the DW in the event that some strong "shop talk language" occurs?

Just a puzzle. So it looks like there is a control circuit for the pump with fuse and control relay. Just need to figure out were in the box it is. My unit is the 680 and really good prints are hard to find. Crawling in and out of the storage compartment has taken its toll on me. Woke up in the middle of the night with a leg cramp and neck is a real pain. Don't ever get old it will kill you. Primer doesn't show up till Sunday afternoon so I'll have all week to work on it. My coach has that truss closing up the upper half of the access door just to add to the fun.

Actually may be needed when putting it back in come to think about it

Scott, if you don't already have it, here's the 680 manual with schematics that I found online:  http://www.hwhcorp.com/ml21001.pdf

Searching the PDF for "3A" for that fuse, it shows up in the drawing of the limit switch indicator box but no where else?  Did you unstack the HWH boxes to see if there is one hidden behind another?

There is only one fuse 7.5 amp ride height. So removed lock strips and bladder. Although it looked in pretty good shape it was very much at the end of its life and you could tear it easily by hand. The adhesive on the other hand is quite robust. This is underneath the bladder to cause the bladder to go flat when it deflate with vacuum. It's 42° And adhesive is too soft to pull at that temperature and just tears so I tried heating it with a heat gun and they just made things worse. Oddly putting a soldering iron on the rail and then following the roll of adhesive with freeze Spray keeps the tape from tearing and you can work it off much easier. No fun

So the preheat then freeze spray the adhesive is working pretty good. Bottom edge done was up to a foot a minute. Did lower aft 8 feet with no tears or stops. Starting on verticals. Will require a bit more thought

So just finished removing the adhesive. The heat and freezing the removed tape keeps it from tearing off. I was really dreading this part of the job and it's done. I thought the top would be difficult but the big iron I was using only fell and hit me once. Heat rises so it was going right were I needed it to. Back to cleaning and figuring out wiring 👍👍
