I finished installing the Jokerz PWR coolant brick, FI's Blower Spacer Plate kit, & Steeda Engine Mounts on the 3rd. Took the car to work on Friday.
Testing was interrupted by steering assist, drive mode, & advanced trac faults.
Immediate thoughts:
Luckily, the car went into save battery mode while running so I have a clear start point.
BMS reset - no tools required
I had the charger directly on the negative battery terminal. Apparently the BCM don't like that. My trickle charger connector is grounded to the body but max output is only 2 amps.

I'm charging it properly grounded tonight with a higher amperage charger. I'll try the options below if this isn't the fix.
BCM reset
Current sensor locations/unplug
Cars are pain
Testing was interrupted by steering assist, drive mode, & advanced trac faults.
Immediate thoughts:
- What else did the mouse chew through?
- What module did I piss off by disconnecting the battery for a couple weeks?
- What did I crush while shuffling and lowering the engine?
Luckily, the car went into save battery mode while running so I have a clear start point.
- Inspected alternator and steering assembly (had my hands all over them during the motor mount install).
- Output voltage from the alternator is 14+.
- Battery is less than a year old and read 100% on the tester.
- Battery quickly dropped below 12.5v.. Bingo!
