We have an ongoing problem with these Curtis BDIs that are private labeled for Linde. There are the style with the 10 LEDs.
What happens is that they get electronically stuck on a particular LED and will not change. It is absolutely a problem with the BDI and not the truck or the battery.
We have plugged several different batteries into the truck and the LED position won't change. We have charged each battery and still the LED position won't change.
The only thing that has worked is disconnecting wires at the BDI and putting the BDI into another truck.

What gives?!
