i see now your relay plate can fit 14 relays .. will look at autodata again laterComment

Re: 12v 1uo941243c Relay repairable?
Thank you very much, will it fit my car? because as you see on my plate i have some relays more exactly 4 which contains 2 integrated dual relays like number 455,389 which are clear but then 175 and the one which is between 100 and 409 this makes it difficult and follow your pictures but the pictures themselves they are ok. do you have possibly schematic to fuel pump on your autodata?Comment

i have it but can only save as xps and it looks like this website cant deal with it .. will have to learn how i can change it . ah will put on stick and plug into linux pc .. autodata is on my windows work laptop .Comment

what codes are coming up on your scan tool ?Comment

Re: 12v 1uo941243c Relay repairable?
P0725 rpm sensor circuit . P07255 not found please check code .
thinking the crank sensor wire breaks right next to sensor .also failing battery will cause problems starting
P1780 not found
P1850 not found
autodata hasn't got transmission codes .
clear all codes and see what comes backLast edited by petehall347; 09-25-2022, 01:49 PM.Comment

Re: 12v 1uo941243c Relay repairable?
i have cleared three four times the codes but they keep coming back and the car still cranks but does not start maybe i should try to find this sensor and clean and test to see what it gives . petehall347 i appreciate and thank you for your support and wonder if i can pm you because i think we are off electronics topic on this threadComment

Re: 12v 1uo941243c Relay repairable?
plenty of electronics involved . if you look at live data on your scan tool it should have rpm .. or maybe not depending on the scan tool . also if you have an an oscilloscope you can check the waveform directly from the sensor . will tell you a story about this .i was called out to a job the experts couldn't fix i hooked up my bench oscilloscope and the car started up .after that it started every time .not saying this will work for you but you can see if sensor is working ok before checking the wiring ,Comment

not just the sensor - clean the flywheel or whatever it is sensing.
i know on some old cars if you got lots of mud on the toothed wheel it couldnt sense itComment

Hi. I need help from wiser guys. I am amateur in electronics and can't figure this out by myself.
I bought faulty speakers, M-Audio AV40's. Other speaker has all the electronics in it and the other speaker is just passive one powered by the other speaker's amp. Original problem with the speakers was loud buzzing. I figured out that there is something wrong with the capacitors. I went ahead and replaced every electrolytic capacitor on the PCB. The caps are good quality and have the same values as the original ones.
After replacing the caps I started testing out the speaker. It seemed...09-10-2025, 10:20 AM -
Dear members,
I have a linear variable power supply with unknown brand name that I used for voltage injection.
Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
In addition, I discovered that its zener diodes are defective.
I can replace the burned transistors.
But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
Therefore, I cannot replace the zener diodes.
I do not want to test the zener diodes in a test circuit to discover their model or value.
no schematics are available... -
Yesterday I successfully repaired a Middle Atlantic UPS2200R-IP that had inadvertently been used as a surge suppressor at our transmitter site. It has already been replaced with an updated one but it's coming home with me now instead of being e-cycled. To be specific, this is the MA model that has the blue backlit display and has been discontinued, although this design may have been used in many UPS units including the smaller Middle Atlantic ones in this series.
Here's what happened: We experienced a brownout/surge at the site, which damaged the UPS and took our broadcasting... -
I was working on this CNC machine today found no keyboard functioning no control relay powering on
The screen powered on and was giving an operation error but the manual was not very clear about what the error exactly was but with a little bit of troubleshooting and finding out that the control relays not powering on and no keyboard functions we narrowed down to this one switching power supply which of course does not have any indicator LED light they are on the keyboard interface/relay controller board
Found shorted diodes on main controller relays there are 3 of them that... -
Hello everyone,
I'm turning to the Badcaps community to help me troubleshoot the radio Rx card from my (old) garage door opener. While I could just ditch that card and replace the whole system, I first would like to understand "why" it suddenly stopped working, because that's just how I am wired...!
Some basics: the receiver works on a 30.875 Mhz frequency. Yes, I'm aware this is not in use anymore in a looot of places. It does not use any rolling code, it's just a regular dip-switch code that you have to set up on both the receiver and transmitter. The receiver...
