Need response from a Castle tech for MMM question

[TruckBasher]

Lito, no need to remove it...its for back feeding the MMM

Brian, just curious if USB can back feed brains while the switch is off/batts disconnected do you think we can back feed the MMM brain without your mod but leave the switch off?

BTW i got my 2nd MMM but not sure if I want to mod it cause the first one is already out of warranty and I dont want another junk.....I sure hope we can find solution to this mess
