Another minor complication. The Ford MME SSM and TSB just say to connect a 12V battery charger. When my dealer programming was clearly going to run hours overnight (which it did), before leaving, I reminded the tech of the 12V battery drain, and he wheeled over and connected a giant 12V unit on wheels (probably 200A+).
My first thought for DIY driveway programming was just a 10A or 20A battery charger, but my first choice turned off by itself last night, so that's a definite no go for long programming sessions.
The more I read, it seems the pros use 12V power supply like units, specifically designed for J2534 auto programming. Apparently the OTC-700A is a highly regarded unit, however it is presently unobtanium.
These Schumacher INC-100 units apparently had a good reputation at one time, but current reviews are mixed to abysmal with multiple warranty returns reported.
I am going to try the Clore-Automotive-PL6100-Charger-Reprogramming unit. None of these are perfect, but this one looks to be one of the better ones with good availability. Also available on Amazon. The Clore 100A charger unit is less than $100 more, but I do not think MME needs the higher current rating.
Depending on what MME is doing on its own (pumps, lights, etc), 20 or 30 amp 12V loads are common, but I am hoping 60A is overly cautious. I think a safe assumption is that one cannot rely on the MME DC-DC converter coming on, especially when re-programming certain modules.
