BMV 712 Displaying "69 AUH INPUL" followed by "SLArL" during "

20190821_143603.jpg. Reset display multiple times because first it was showing a constant 2.8A+/- draw with no load. Then finally reset again and load went to 0A but stayed their regardless of load. Voltage registers. Next reset, updated Batt capacity and then got prompts as in title except where there is a "L" it was really an upside down F. See pic. Hit down again and get next pic.20190821_151858.jpg , and next is 20190821_152751.jpg. Can not reset. Disconnected cable and reconnect, no change. App is showing Voltage but no current usage. Appears apparent display is bad but want to check before returning.

It is a seven segment display.

"69 Aux Input"
Image 143603 is saying "Start" as in Starter battery.
Image 151858 is saying "Temp" as in Temperature.
Image 152751 is saying "Mid" as in Battery Midpoint measurement.


There is nothing wrong with the unit, this is the way that seven segment displays show alphabetic characters.
Do a zero calibrations to get zero amps when you are certain that no current is flowing through the shunt.

No amp reading is a bit strange.
Do you have the shunt wired up correctly? This is the mostcommon cause.
If you could provide a picture of your wiring especially detailing the shunt, that would be ideal.
