Tonight we fix up an A1466 DC IN board, something that used to be just thrown in the rubbish, we now repair and save, because they're getting expensive! This time we're lucky that the dim output lights on the Chipmunk USB tester are being caused by a pair of corroded resistors, which happen to be the current-limit setting pair for the USB power switch chip, the same one used on a lot of other Macbook boards.

Second Macbook job is an 820-00239 board that has no power on any of the USB-C ports. Again, we're fortunate, there's some very distinct corrosion around one of the CD3215 chips and a quick clean & inspection reveals a missing resistor and a key broken trace.
