Airing Up without HWH Control Box

I sent my HWH control box in for repairs and it's on its way home now, however, it's won't be here until next week. Over time, I lose air on my right rear and the coach gets the droopies. My compressor just went down for the count (seems that everything I own is breaking!) so I can't air up the coach externally. Here's the question:
With the HWH control box removed, can one start the coach and will the bags fill? Thanks.

I can fill mine from the air chuck and connecting it to my compressor in the garage.

You can air up the tank with shop air but you still need to open the raise solenoid to move air from the tank to the air bag.
I think the raise solenoid gets it 's power from the HWH computer.

I guess with the computer removed you could find which pin powers the solenoid you want to power open and jump 12 volts to it to open it and get your coach back up.

I should have been more clear. My garage compressor is down so I can't use shop air. It's really no big deal so rather than trying the 12v to the right pin plan, I'll just look the other way when I walk by the coach. Thanks to all.

JOR,
I understand, maybe you can block (or use a small jack) that corner so it doesn't go down further and twist the coach more especially if it could be that way for a while

Can you drop all four corners. You do not want one corner to drop and the others to stay up as that will start a twist and your windshield might not like it much.

Looks like I can't in that I don't have a control box hooked up. I sent a mail to HWH asking them too. My box will be here Tuesday and all will be well.

I called HWH yesterday with this question. I was advised of what we already know - they are way behind on callbacks for tech problems. I asked if email queries were answered more promptly. She didn't know but did give me the mail which is service at hwh dot com. Told me there is only one guy handling these queries. Anyhow, I sent an email yesterday afternoon and it was answered first thing this morning. So I'd say email is the way to go for HWH tech inquiries.

BTW, JohnD was correct. Here's the response.

You can start the coach if you like but it will not fill the air bags. Without the control box in there is nothing there to energize the travel solenoids and if they are not energized the ride height control valves can not send air to the bags.
