Iveco Daily 2.8 - Not working viscose, no power supply, diagram needed

Question

Hello I searched and found no solution to my problem. Daily 2.8 35c11 106KM patient, ordinary pump, 2001 viscose not working. That is, the viscose is new, the temperature sensor in the radiator also does not turn it on. After connecting the pins in the sensor plug, there is no reaction, while...

The sensor in the radiator is designed for direct switching, without the need for a relay. To cover the topic you do not need electronics, the topic with your knowledge should be in the beginners section. Please send it to an electrician and a moderator please close the topic.

Hart3 · Answer

I doubt there would be a viscose, ordinary electromagnetic clutch for the radiator fan. Power supply from fuse 23 through the contact of the temperature sensor. radiator to the clutch, no relay. What voltage after a sensor short circuit looks like there is a power drop somewhere. Fuse center on foil with copper paths, after overheating there often drops in voltage.

piorom3 · Answer

Yes, electromagnetic clutch Can you tell me which fuse 23 is? There is no numbering on the fuse board, only illustrations. Fuse switch on foil in this year? I did not unscrew it but I see only ordinary cables there

Hart3 · Answer

The image of the central unit and part of the diagram.

piorom3 · Answer

Well, we do not understand because in 2001 in my car the fuse board looks like this (maybe not so nice because not which pins are burnt at my place but I generally have one)

Hart3 · Answer

Daily II with such a board I met at the engine with the computer. Switching on the fan clutch via relay 25336 i.e. in your photo first from the bottom left. Power supply from fuse 31 i.e. from the bottom second row from the left. EDC version controls this computer. I checked, in C11 version without EDC, power supply from fuse 31 without relay.

I give a real photo of my fuses, the problem with the type of plate may be due to the fact that I checked my car after VIN and it was the English version, the seller said nothing. For this reason, I bet that something is badly connected. The fuse is checked, the relay is also. After shorting the pins in the sensor plug, it does not switch on the solenoid. You will probably need to make a separate power supply from the relay installation, but which relay should be installed correctly?

Hart3 · Answer

Well, so different things can be expected with such a guerrilla. You are wrong to inform that you have a relay, from the attached photo you can see that the socket is not planted, compare with the previous photo. This fact is not important because as I wrote in the 35C11 version, this relay does not have this relay. Your photo shows that the fuse is green first from the bottom left. Pay attention to the value of your fuses, totally overpriced. The colors of the pictograms should match the colors of the fuses. Despite my efforts, this is not much.

piorom3 · Answer

As I wrote, I already bought one. So it's better that he deal with this connection of electronics?

Megawe · Answer

There are two types of coils for the electro-clutch fan, with two outputs and with three.
It depends whether the car has a climate or not. Coils are quite expensive. If they burn, you will feel burnt plastic.

piorom3 · Answer

I see that you have not read my posts thoroughly, I have all the electrical coupling new (the old one has fallen apart). There is simply no power, after shorting the pins in the plug from the fan sensor, the fan still does not turn on. After applying the current with a separate wire to the electromagnet, everything works

Megawe · Answer

The relays should be in a box in the engine compartment. The electrical wiring around the brake servo is most often damaged.

Hart3 · Answer

Buddy in post 6 you have the relevant diagram, what is the problem of its reproduction. On the radiator you have a sensor, supply power to it and connect the output with the fan clutch. Simple?

piorom3 · Answer

So simple, but in addition to the fuse (and current rather from the ignition) you need to protect the installation with a relay, what to choose? What scheme? I have a lot of relays from BMW, because I trade parts for these cars, just admit that I do not have such a concept in electronics to choose the right relay and not to burn something. I prefer to inquire before testing

piorom3 · Answer

I took care of the subject myself, the sensor receives power, while somewhere the rest of the installation was mixed up, I connected the plug to the solenoid with mass and power from the sensor with a 5A fuse, everything works as it should, the temperature does not go over 90 degrees
