When repairing ford EEC-V PCM for various faults, start by probing each black SMD resistor on the backside. Those are of notoriously bad quality and they normally go open. Please note you must have very sharp probes of high quality before attempting to measure each resistor. I recommend Probe Master 8000 series kit:
This is what you need to reproduce a new El Jet 4 Car controller
This file contains SprintLayout original files. It contains Gerber files for production. This file is working. It’s verified. It also contains a correction to the original PCB, ie not requering a bodge wire anymore. It can be downloaded from here: https://www.dropbox.com/s/jdhti6q6ryj3p92/eljet4gerber.rar?dl=0
Repair of defective Video 8 player. Would not accept cassettes. Would pull them crooked and then eject immediately.
Upon disassembly, found cracked cog in cassette inject/eject mechanism. This cog is not available separately, only as complete assembly. Not possible to order – did not find any on ebay.
This cog cracked and the mechanism did not pull straight. This is a picture of the cracked cog.
This is a nylon cog. Due to age, it shrunk on the steel axle and cracked. Not possible to repair in any way. No superglue, melting or anyting will work. I had to redo the part in FreeCAD and send it to 3d printing.
This is the part i made in Free Cad. This is the file.
Here compared to the old gear. Perfect tight fit. Put a drop of superglue to fixate it in place. Original gear is pressed into place and very stubborn to remove (if not cracked). I did not want to make the gear THAT tight. This is better.
new gear installed, old gear on top for reference.
Now inject/eject mechanism works great again. Please make sure you notice the small position switch on the left side of the drive when reinstalling the eject mechanism….
The goal with this document is to teach the pupil in the concept of multiplication with 1…10, ie learning the multiplication chart the visual way. Squares should be colored and the corresponding numbers written on the edges by the pupil. Designed to be printed on A1 paper with 1x1cm squares.
The goal of this project is to disassembly and reverse engineer Car Controller 4 and 5 for the benefit of other Kewet Users. Bom list will be produced soon.

Ladda ner denna PDF-fil och skriv ut multiplikationstabellen dubbelsidigt på A3 papper för att göra egna flashkort efter att du klippt ur dem. Vänligen tänk på att du måste skriva ut dem i Acrobat Reader där du kan välja vilka lager du vill skriva ut. Du får sedan ladda samma papper flera ggr för att få allt dubbelsidigt.
