well they seem the same size to the naked eye the only diff is the 399 = sr927w and the 395 = sr927sw tried them both
tried various ac reset think the problem lies in the double battery think theirs like an order of points that need to be shorted .. as said remember giving up on it thinking the module was shot on the other one then gave it a last play and got it working but just can't remember what I did
from mem the sw vs w... sw slow drain on a battery and w normal drain if I remember right![]()
