That rules out the direct connection to the ECU but I don't think it's a relay causing your fuse to blow and three error codes.
I think there is a large connector behind the battery check that.

they do not blow anymore now there is no more power flow and it 3fuses

The ECU on this car is located with the wiper motor I took out and it looks almost like new even inside. Don't you guys know how to test these multi pins. relay? Because with all the help that petehall347 has contributed I still have some relays that I don't know their purpose just because supposedly they handle multiple things at the same time

i wouldn't be messing with all that stuff . instead i would be getting it running then see if anything isnt operating properly .
did you fix the rpm sensor yet ?

it's right what you say but when I don't get power to the sensor and ignition coil and also not to the fuses 28,32and 34 which all have ignition to do then I go crazy

Check the connector to the ECU that's behind the battery.

First you would troubleshoot and fix the blowing fuses problem, why are you now suspecting the relays? Look for the short circuits instead of wasting time here.

thanks but after the fuse was blown I no longer have any power through so I can't find the source and then it would be good to know that those relays are working properly. what I understand from your post the relays have nothing to do with the fuse or am I wrong

everything is marked on the wiring diagram . there is also a list of everything you can search the pdf .

Hi again I was wondering if you or maybe someone else here in the forum who knows how to test a 6pins,7pins,9pins and even twin relay. Have searched everywhere only find how does an 8 pins different relay work or maybe refer to something that can help. some pictures to understand

Thanks these were not with the others in your last post.I'm trying to put them together so I can understand what it looks like.
Sorry now i see they are here

f29 powers A52 Ignition amplifier. unplug it to test if short gone .
its right there on the diagram ,
that manual is on google ..its a skoda factory one

Hi I find no F29 or A52 on the Diagram but you said "f29 powers A52 Ignition amplifier. Pull out the plug to test if there is a short circuit.
It is right there on the diagram, can you point to what you are saying please

Re: 12v 1uo941243c Relay repairable?

there is a workshop service manual for the electrics online .. you will maybe need to make your own breakout box .
what i do is find the resistance figures for the sensor and remove and inspect the suspect sensor for damage and check resistance .

do you have any specific link to this workshop service manual? i searched for autodata but they are very expensive even though they have one..very cheap first month. what do you mean by making your own breakout box. the fuse that is no:29 on the fuse box has has to do with petrol engine, engine electronic and ignition according to the manual

Re: 12v 1uo941243c Relay repairable?

which fuse is blowing ? what did you do just as the fuse blew ?

fuse that destroys all the time it is no: 29 on the fuse plate and I do not know to which relay it belongs the schematic on post 47 that you posted differs a little from my plate.

Here is how I troubleshoot a short circuit with out a wiring diagram but this takes a long time to do

You have to gain access to the back of the fuse box and trace down the circuit that has the issue and start taking of the tape off until you get the first connection point and keep going down the wire path until you find out where or what is causing the short

One option you have to getting a wiring diagram for the car in question is go to the dealership and ask them if they will print out the section that you need I have done this myself in the past and have gotten good results from doing this now you might have to pay a fee for them to do this for you

What amperage is the fuse in question

STJ point is also something to look at as well

“ check inside the ecu
just in case a cap has leaked - very common in Honda OBD1 era stuff ”

On some cars there is camshaft sensor and a crankshaft sensor and they give you the same exact error code for both at least this is the case with the car that I have so do not over look this when I get this code I change both of them

One note some times it can be the wiring harness plug that can give you a bad headache if it has a bad connection in the plug as well and it can be hard to detect and determine if this is your issue or not

On note about a fuse that blows as soon as you apply power to it you need to find out what is causing this issue use the incandescent light bulb instead of the fuse to see if it is a direct short or not you will need a wiring diagram for this car to be able to know all of what is on this circuit

I have a pickup truck that has an issue when you leave the truck sitting for a couple of weeks and go to start it the battery is completely dead no power what so ever I going to have to figure out what the issue is but two things come to mind first one is the radio and the second one is the alternator bad diodes in it and Ford alternator are the worst for this issue I have had this issue several times in the past

A few years ago I had issues with the charging system on this truck and it was one of the pins in the wiring harness to the alternator that was the issue that time

that's right camshaft sensor and a crankshaft sensor could be the cause but as you say i need to have wiring diagrams for this car petehall347 has helped me with that hope he continues with it because now i'm stuck with a fuse that blows all the time
