Power on MacBook 12" A1534 without battery

Testo:

My MacBook doesn't start and shows permanent the red bad battery sign like on an iPhone when there is no power.
+
This battery sign doesn't let me through any system. No BootDeviceManager, no Reinstall menu, no maintenance menu, No SMC reset, no NVRAM reset,...
+
Its just turning off after showing the red battery sign.
I would like to know, if I could bridge the battery contacts. So I could use it as a desktop PC and know if the logic board is broken or the battery.
Can someone tell me where I have to connect which kind of power?
What i found out:
* The big middle contacts seems to be the output pins with 8,59V.
* The Label on the Battery is telling me that it has 7,56V, which is the battery output?
I would assume that I could bridge the 8,59V pins to the pins on the right side next to the output, but I don't know if this is a good idea and if yes, which contact is plus and which is minus. And what is the single left pin for?
Would be cool if i can start this thing without the battery.
