Thank you fishmech.

I bought a Curtis full level 1313 handset last week. I was able to reset the maintenance minder and max out the hours where it shouldn't come back on. The red wrench light went out and no more messages.

The BDI still has me in limp mode. Battery is at about 25.6. I've been charging it with the onboard charger. Then, I tried charging it with a different charger by pulling it next to another truck. Finally, I plugged a different battery into this truck but getting the same BDI warning. I may have overlooked while digging around in the handset, but is this something I can reset with the programmer?

Thanks again!
