No need to freak out about any water sneaking in and causing earth leakage! The RCBO's got your back and will shut off the power in a heartbeat if it senses anything off. And don’t worry, the car’s covered too, any sign of earth leakage, and it’ll handle it super quickly.
If you can swing it, get a pro to check out the health of each battery cell in the pack. You’d be surprised, sometimes just one bad cell can throw a wrench in the whole setup!
I agree with @JC Grifter.
Grab your iPhone, hit up Settings, then Bluetooth, find your car in the list, and just tap on Forget Device. Once that’s done, give reconnecting another shot.
You don’t usually need to disconnect the HV/12V for 30 hours with the OBDLink SX and Alfa software. Unplugging the battery can reset some modules, but you can handle proxy alignment and issues directly via OBDII without that hassle. Just ensure the vehicle is safe to work on and follow...
I had this issue a few years back. My car was stuck at 47% and in limited power mode. When I plugged it into the OBD, it totally refused to connect. It was such a hassle!
