2018 Greyhawk levelers

[LeighW]

Just picked up my new unit yesterday. So much to learn and manual is unclear. I know parking brake must be set to start auto level. But is engine running, key on, no key in Ignition? What am I doing wrong?

I don't have it in there yet, but mine is a 2018 Grayhawk 29mv. My manual says ignition on, engine running, and parking brake on

I suppose I've been doing it wrong. I've been putting the transmission in PARK.

The manual for the 2016 Greyhawk 29MV says:

The 2018 Class C Grayhawk manual says in park not neutral. Wonder if changed since 2016 due to a liability issue? Someone may have not engaged parking brake enough and unit rolled.

Like others here, my 2018 is trans in Park, parking brake set, engine running.

Sometimes I get the process out of order and go start the engine before I pull in the slides. It won't let me do that; the slides have an ignition lockout. It would be easier if I could go start the engine, walk over to the control panels and pull in the slides, then pull up the jacks, then hop behind the wheel and leave. But nope, I have to bring in the slides, go start the motor, go back and pull up the jacks...

My wife does a room check around the slides and brings them in so I can do the outside stuff with out hitting my head. She cranks the engine after that. Being 6’ 2” the slides want to jump out and hit my head. LOL

I suppose the important takeaway from this, is to check your specific owners manual for the procedure for your brand of jacking system.

For example. mine has a wired lockout and alarm light that won't allow the system to work if the engine is running.

From the leveling system installation instructions:
Step 1 - Keypad Ignition Disable Circuit:
Note the “break-outs" near the end of the keypad harness. The Pink wire must receive a +12 VDC Input when the ignition key is in the “on” position. Connect this wire to the ignition positive. This will make the wire "hot” and will inhibit jack extension when the vehicle ignition key is in the on (engine run) position. This also provides for a “jacks down” warning in the event of a jack drifting from the stowed position during travel. This connection is required. Failure to make this connection may create an unsafe condition and may void the warranty..

Must be what brand you have. Ours is hydraulic and engine must be running or we get a message on the display “low voltage”.

My 2017 Greyhawk's levelers only require the parking brake to be set. I always have the engine off. The slide and levelers take a lot of battery power to operate so I have gotten in the habit of firing up the generator while extending the jacks, slide, awning, Direct TV dish. That way the batteries are not immediately sucked down before camp is set up.

Another problem I had with my jacks is that Jayco mounted them too low and they would scrape at times. I looked up the manufacturer's specs and found that they were about 1.5" too low. Had my son move them up which just consisted of picking a different mounting hole. Problem solved.
