Additional Information
Some fuses don’t have the usual look you’re used to seeing in cars, but their functionality is the same. Conventionally, all of them can be divided into fusible and automatic.
Checking the fuse
- Remove the fuse from the module using pliers and visually inspect it.
- If the fuse wire is blown, replace the defective fuse with a backup fuse.
- Turn on the consumers of electricity and check their performance. If the fuse blows repeatedly, have the electrical equipment checked by a qualified specialist workshop.
Checking the automatic fuse
When the automatic fuse is activated, the pin (4) moves to the off position (2).
- Remove the automatic fuse from the module.
- Press the pin (4) to the on position (1).
- Click on the release (3).
– If the pin (4) moves to the off position (2), the circuit breaker is OK.
– If the pin (4) does not move to the off position (2), the automatic fuse needs to be replaced. - Press the pin (4) to the on position (1) and reinsert the automatic fuse.
- Turn on the consumers of electricity and check their performance. If the automatic fuse blows again, have the electrical equipment checked by a qualified specialist workshop.
That’s all. There is something to add – write in the comments.
Hello, my truck air conditioning fan system is not working, can any help me? Actros is mp5.
Hello,is there a fuse or relay that can stop the engine for actross when you remove it
HELLO,IS THERE A FUSE REALY THAT CAN STOP THE ENGINE FOR ACTROS WHEN REMOVED?
Can l have brake circuit diagram for actross 2015
Please show me there aircon relay
