Codes 19 and 21, new to me machine

Hi everyone, new here.
This is my first electric lift, I bought it in unknown condition.
It's a 2007 Crown WAV50-118, it appeared to be complete upon arrival.
The batteries were flat dead and it looked to have sat (outside) for a while.
I bought four brand new G2 batteries for it, put them in, and the unit now powers up but is otherwise inoperable. I found a code diagram online, and here's what I have come up with so far.
Without the gate shut, I get a code 19. Like to recalibrate the pots to eliminate that as an issue, but I haven't been able to find a how-to on that yet.
With the gate shut, I get a code 21.
The machine has no functionality whatsoever other than the key on turning on power, green ignition light, etc.
The push/drive switch by the charge port properly disconnects the drivetrain.
Thanks for everyone's help!

Hey Ian,
Based on the info you provided the first thing that comes to mind are the occupancy sensors for the handles. I imagine if it were outside then the holes could have debris in them. Its the easiest thing to do so its worth a shot. You'll find the holes beside your knuckles when you grab the handles.

Fact of the week
The two internal cavities in our nose called nostrils function as separate organs. Each nostril has its own set of turbinates and olfactory receptors. The two independent organs work together through a mechanism called the nasal cycle, where one nostril is dominant for air intake while the other rests and is better at detecting scents.
