Yesterday was wasted waiting for the UPS truck.. It came around 5:30 PM and gave me my Amazon order..
But, someone at Amazon mixed up the boxes and sent me the wrong stuff..
After a trip to the UPS store this morning, I drove over to Brogsie's house and picked up the dead A7.
Plus a new temperature control unit, still in it's box from the vendor!
Only a few feet of copper left over from the long HX loop..
It looks like the leak might have been were the HX loop connected to the larger copper going inside the A7.. Bottom part I think..
