Re: What are the requirements you need to meet for extra needed unbag time?
Reading through your other thread, indications point to your lift motor being the problem. Last year we had a similar issue. We used a mini cim on our fuel intake and at some point the wires got pulled which created a short at random times. We had checked everything we could think of and found the shorting out motor by accident when someone rested their hand on the motor while we did a systems check. The pressure was enough to move the motor to the point it shorted out and we lost comms.
We switched out the motor and no further issues. The reason, we determined, that it was random was we rarely activated the fuel pick up and only if a fuel ball came up in a certain path was there enough pressure applied to make the motor short out.
I know you had a motor expert say it wasnít likely for a motor to short, in our case it was were the wires entered to motor housing. Itís worth checking as it sounds like your lift motor gets a lot of use and is when you lose comms.
