Based on two days of watching it seems to be an after charging event. If you charge and drive maybe the exercising of the battery takes the place of running the pump. I will watch closely tomorrow as I will take my usual 42 mile drive to work immediately after charging. Hopefully the pump will not be running for 9 more hours in the parking lot after my 1 hour drive to work.
Any update on the pump running again after your last charge? Thanks.
