Yellow light and alltrax controller

[alangsam]

2018 Prefedent Replaced stock controller with alltrax400 regen
Should I expect the yellow battery light to still come on @20% or did that
go away with the switch to the alltrax?

The Yellow light no longer works, it was activated by the stock White Curtis controller.

From another post by Tahoe

The yellow light is controlled either by the OBC (if equipped) or the ERIC controller on the car (If equipped).

Walt, I think you are correct for charging instances, but I ~believe it is from the controller when in normal operation and no charger attached. I will see if I can find some info on it or maybe David or Sergio or another member may already have the info.

Found it. Check this out.

ERIC Charge Indicator Light:
The light serves two functions and initiated by the Curtis controller:
1) Battery low state-of-charge warning, and 2) Charging confirmation.
Battery Low State-of-Charge Warning
• The light comes on and remains solid when the battery state of charge falls below 20%.
• The light begins flashing when the battery state of charge falls below 10%.
Charging Confirmation
• The light will flash three times and the reverse buzzer simultaneously will sound three times to indicate a battery charging session has begun.
