AN86:
Guess ill have to remove capacitor and see. Ill do it and let tou know what i find out, and hope for best :)
AN86:
I did remove capacitor and replace it with lets say similar, i know its not good choice but i wanted to see if there will be any difference, and it didnt make a difference. But i notice something. On the board next to the IC6, which gives output of 1.2 and than drop to 0.8V, there is a probably test dot that said 3.3v. and when i probe it i have exactly as on the output pin on IC6, and then another test spot that has label 12v and on that spot i have 0.004V which is crazy and i guess maybe there is a problem. On the cylindrical capacitor behind the board near that spot i dont have 12v only ground. And capacitor is polarised. Ill try to snoop around. Picture attached just in case i didnt explain good.

Your voltage regulator IC6 is shorted between the output and ground. This can further drain your battery. Odds are the short is at the MCU. Can you measure the temperature of IC6 by chance?

I have that ebay digital laser thermometer. I try with him and let you know.

Check ZD2 and ZD5 for short. Usually 5V1 diode go short. If so replace it and if you are lucky you good to go.
