FIX: Rottendog MPU089 batteries draining quickly and losing settings

(1/1)

Ken Layton:
Problem: MPU089 runs the batteries down to dead overnite. All settings lost and you get the "Factory Settings Restored" message on the display.

Cure: Found diode D1 (located directly to the right of the lower red LED) was shorted. It's a type 1N4148. Truly a cheap fix.
