MacBook keeps starting and shutting down

So, I spilt coffee on my macbook and tried to fix it by cleaning it with isopropylalkohol. Right now when the charger is plugged in the fan runs, the red dot is shown and it boots after a while. Unfortunately every time it boots it shows the apple logo and a loading bar which loads to about 1/3 before it shuts down, it then immediately boots up again. It will keep starting, loading and dying until I unplug the charger which it dies.

Any help is greatly appreciated!

The MagSafe charger is telling you you either have not given the system enough time to charge or the battery is not accepting the charge.

You'll need to disconnect the battery and just using the MagSafe charger see if the system will boot up with it alone.

When disconnecting the battery it does not turn on at all. I've also noticed that the MagSafe charger doesn't show the red dot anymore but the behavior is still the same.

EDIT: The charger is pretty beat up

@yzdnegel -Is the MagSafe LED Green now? Did you try disconnecting the battery as I recommended? Follow this guide to Step 3 2017年早期MacBook Air 13寸 电池更换

I disconnected the battery and plugged the MagSafe in and nothing happened, there is no light from it at all. I tried starting it but it won't start.

EDIT: If I reconnect the battery again and plug in the charger it will continue to start and shut down like before

Sadly, this is a much deeper problem! Your logic board charging logic has issues! This will require someone with deeper skills to diagnose which MOSFET needs replacing and you may also need a new battery as well.
