The undervoltage error on your Edge 3 power wheelchair, especially when encountering inclines, suggests a potential issue with the battery or power delivery system. Error code 34, indicating a bus voltage drop, further points to a drop in electrical power while traversing inclines. This could result from a failing battery, loose connections, or issues with the power distribution system. It's crucial to inspect the battery condition, ensure secure connections, and consult the user manual for specific troubleshooting steps. Professional assistance from the wheelchair manufacturer or a certified technician may be necessary to address and resolve this complex electrical issue.
That's the problem with buying used parts as they take a chair that doesn't work properly and see the parts off., even the part that caused it to fail and be sold or scrapped.
Send that part back and buy new. But what if the controller is not the issue though.

It comes out the front also.....but it is a real pain if the cabling was put on with out any thought the last time they were replaced. I had to hire a neighbor hood teen ages to get down and "walk" the battery out by rocking it back and forth.
Edited text for clarity. Moved from Computers to Power Wheelchairs. Larry, the Fixya category is misdirected and lands in Computers for this model.
Tthere appears to be many variations of this model. Check that the batteries were correctly installed for polarity. Disconnect, wait 30 minutes and reconnect. This is as close to a controller reset you will get. The manual suggests you need dealer service

I'm not familiar with this particular wheelchair, but I personally often forget to reconnect one flat cable, which in that case is most likely to be your issue?
Hope that helps
