Alta Redshift Code 103 charging drama

my cousin just got a 2018 Alta Redshift MXR shipped in from a dealer in Texas, and we’re already stuck at a standstill. we can’t get the thing to charge for the life of us. it just keeps throwing that Stopped 103 code every time we plug it in.
we’ve tried everything, like multiple circuits in the house and garage, plus a custom pigtail to go from 220v to 110v. we even bypassed the adapter and wired a 110v plug directly to the charger, but still nothing. The dealer claimed it had the latest firmware, but we’re starting to wonder.
the GFCI on the rapid charger is lit up, so it's getting juice, but the bike isn't biting. Should we try bypassing the GFCI next, or is there some hidden trick to getting these things to handshake? we're pretty clueless, anyone seen this before?

I had a friend who was wrestling with a Redshift that just wouldn’t charge. It turned out to be a firmware handshake issue basically, the bike and charger weren’t on the same page. Before even thinking about bypassing the GFCI (which is super risky!), I’d definitely check the firmware versions and maybe try a reset. It can save you from a lot of frustration and potential sparks
 
I once had a similar experience with a stubborn MXR that wouldn’t power up, and I almost ended up rewiring the whole house.
A dealer swap did the trick, but the key was ensuring that both the charger and bike were using the same firmware.
I know the GFCI bypass can be tempting, but it can cause more problems than it solves.
Always check the firmware first
 
Avoid skipping the GFCI. A Code 103 typically indicates there's a problem with the charger-battery handshake.
You should check for firmware compatibility, inspect the signal pins, and make sure the BMS is recognizing the charger
