I have a mv1a board, and i have removed D1, D2 and R10, so that I can use a CR2032 no rechargeable battery.
As per the image here


But when i turn on the board, the positive of the socket gets around 3.3 V (without any battery inserted in the socket). Shouldn't it be 0v? I'm worried that, if I place a battery, it will fry.

I've check D4 with a multimeter (to see if it lets voltage through) but apparently it's in good condition.

Thats just leakage current that causes voltage to be present, common and it won't damage anything.
