someone who has one will be along
IIRC the drill is to turn it OFF "at the inverter" not at the remote panel
unplug the remote control cable aka phone line plug
disconnect from batteries for 10 minutes
then
connect batteries
turn on
check operation..\
IF okay, turn off, plug in remote, turn on again
this helps to isolate problem to inverter or remote board,
if there is a problem with one or the other
I can explain it to you.
But I Can Not understand it for you !
