I’ve changed two flex boards from two different sellers, and I keep having a battery drain of about 25mA after i installed them. The battery drain is not present with the original flex board, any ideas?

Alessandro - Reply

Ok no, little update. the battery drain is present even if I disconnect the flex board, the touch connector and the led . It’s something on the main board I think, but I can’t figure out what is it. Is there some insulation that I may have lost when changing the flex board the first time?

Alessandro -

That sounds really weird. I don’t remember any insulation on this specific model of controller. I don’t have this anymore as it was a repair for a friend and I also hadn’t noticed or measured such a drain.

Devnol -

The only other thing I can think of is a failure on one of the components soldered on the main board, but 20mA in standby condition are VERY high!

Alessandro - Reply

The warning regarding the rumblers being hard soldered and the wiring is delicate honestly should be in step 4, jiggling joysticks to remove the front cover can easily cause the rumblers to be disconnected and require some time consuming resoldering to reattach them.
