Default Hydraulics??

Hey guys, hope everyone is doing well? Gotta 36' Gulfstream(Ultra Supreme), Class A Motor Coach. Slides & Jacks will NOT function? Shoreline, 50 Amp plugged in & getting power into Coach, Reservoir @ Full level, House Batteries @ 13.9... Any suggestions?? There's been mention of 50 amp breaker within Coach, but I can't locate such an item? All breakers in panel are in ON position. Drivers seat is ALL the way in Forward location to activate safety switch. Never had problem with Hydraulic System? Are there maybe Fuses or other Breakers that I'm not aware of? Thanks for any time & 0fferings of wisdom?

generally, for the hydraulics, which can use a lot of 12v amps while operating, will have a large 50amp or even 100amp 'BUSS BREAKER', usually located near the House batteries, maybe mounted on the wall.
These typically also have a little 'FLAG', yellow or red, which may protrude, showing that the breaker is tripped. Push it in to reset and have hydraulics again.

On my coach (GS Scenic Cruiser) nothing is going on when the engine runs. Check if there is a switch who „says“, Engine is running.

I had a similar experience and found a 25A fuse blown. Left front compartment. Controls power to the motor. Much later had to replace the motor but that started with slow response and tripping of a thermal breaker. Find the fuse and you’ll fix the problem.

Default Hydraulics Troubleshooting

I have an Equalizer system. On the back of the dash control panel is a 30A fuse. Check that.

I am attaching (I hope) a troubleshooting guide for the Equalizer system.

Had same problem on 39' Friendship. Finally located 50 amp breaker under the Allison transmission computer next to the cranking battery compartment. A little lever gets kicked out that has to be pushed back in to reset. Good luck !!😊

Not sure about your coach, but on my Scenic Cruiser there is a circuit breaker that controls the levelers and the slides. It is either a 30 or 50 amp circuit breaker, I am not on the coach right now to check it out, but it is a rectangular shaped black circuit breaker and it has a little lever that pops out, To reset it, just push the lever back into the black box which is a couple of inches in length. That circuit breaker on mine is where I have the two big switches to turn off when winterizing the coach or if you just want to turn the power completely off, also other electrical equipment in there, not sure what they all are since I am not an electrician. But yes there has to be a circuit breaker some where for your coach also.

Aside from the 12vdc Circuit Breakers, my 99 Class-C slide hydraulics also have 2) little cube relays that activate to lock out slides when IGN is ON? (Must be OFF) 3) (Some) also have Parking Brake switch (Brake MUST be ON?) or 4) (some) a DRIVER'S SEAT SWITCH so seat MUST be fully forward/ tilted (to prevent seat/ slide damage)?

Sounds like you have a blown fuse. look in the forward storage compartment on the drivers side. That is where mine is on my 37' Ultra supreme
