Title: Force reset of WBJ AH meter - I mean FORCE
Post by: 5 Minutes 2 Midnite on March 27, 2018, 04:09:18 PM
I know you can configure the WBJ to reset AH to zero upon full charge, but I swapped battery packs and need to force the AH meter to zero now. It still thinks the old pack is connected and giving me the reading for that pack.

I have already tried the following to reset AH to zero:

1) Completely power off the controller
2) Completely power off the power to the shunt
3) Turned the WBJ OFF from the local app
4) Changed the function of AUX 2, then put it back

I assume the reading is being saved in non-volatile ram or something. Can AH be forced to zero any other way? The pack is fully charged.

Hi 5 - 2..,

On the MNGP,  press the Status button four or five times to see the WBjr Status  --  the one that shows Amps into/out of the battery,  etc.

Press the Left Soft button "More",  for the Net Ah,   Remaining AH,  etc display.
Now press and hold the Left Arrow button,  while pressing and holding the Enter button.   This should reset the Net Ah to zero.

This should do it,   from the MNGP.
Please let us know if this works,   Vic
