Re: Boss ME-5 battery/ circuit diagram

sorry, I don't have a diagram (diagrams and user manuals seems hard to get for these oldies).

but; my ME-5 took a hard fall to the floor once, which caused the memory backup battery to loosen, all settings where lost. I simply opened the box, measured the battery (small 'coin', flat one) to be 3V, and replaced it with 2x standard AA (R6) batteries in a plastic holder (there's planty of space in there). you don't need rechargable cells, these big ones will last a long time. still works just fine!

and, YES, you must do the battery change with AC power ON to not loose settings. be careful where you lay your hands!
