2. What not to do

2.6. Never randomly bridge MOSFETs/fuse/components
Bridging components can easily lead to the destruction of the board without any way to repair it.
If it's a fuse, replace it with a matching fuse. If you don't, it will not be able to protect the board and if the source of the problem is still there, some other component will go up in flames.
If it's a MOSFET, its purpose is to stop current from flowing through it when turned off, and allow current to flow through it when turned on. It's not necessarily always turned on, otherwise it wouldn't be there. If it's turned off when it shouldn't be, then there is an issue elsewhere in the circuit, bridging the MOSFET won't solve it.
