Congratulations,
examine the wires for any kind of short circuit, also inspect the screws that could cut have cut insulation. Try to replace insulation as far as possible, but be aware that this area could heat up to 300°C - so ordinary insulation tape or heat shrink tubing won’t work & pose a fire hazard.
Good luck!

so i replaced the thermistor and changed the broken fan and now for some reason the nozzle arent at the same height and the left one is lower than the right by like a whole mm.
Hi again,
as written before, the process of leveling both extruders is described in chapter 2 of the SV04 operation instruction. In case the nozzle height difference exceeds the compensation options: One nozzle needs to be screwed into the heat-block in order to change height - a full turn will change 1mm. This requires dismantling the current extruder iot access the heat-block, heating it up iot get the filament liquid, using a wrench iot loosen the nozzle, screwing the heat-break out to new height, screwing in the the nozzle. Nozzle & heat-break must be screwed with sufficient force to ensure a tight connection iot prevent filament spillage. Be careful not to tear the heat-break apart with too much force. Gloves will prevent skin burns.
Good luck!
Björn
PS: You have installed an axial fan on the left extruder. This fan will not be able to cool down the freshly printed filament, as its airflow does not reach it. A radial fan with a suitable fan duct is required here.
