Whit no sophisticated media, you can build by yourself a tester as useful as the original BMW one but much more cheaper.

 You can make a simple and elementary one, that would be about this, that needs more wire and more and has two independent circuits, one of them fed with a 9 volt battery to test ignition and the other with no fed to read ABS codes, testing injectors signal,... all assembled into the same casing:

 Other resource, a bit more sophisticated but more simple on shape would be this other. A transistor is used as a switch to light the led diode when Hall sensors or ABS signal is present, depending on switch status.

    When switch is on, the circuit feds Hall sensor and receives signal from it when ignition point is reached. This signal polarizes the transistor, that connects the led diode to ground.


  When switch is off, the circuit dont send fed out to anything, it only feds the positive pole of led. When ABS or injectors signal is received, transistor polarizes and the led iluminates.


  Transistorized tester.

I have used an old tyre pressure tester case to hold in the circuit. I never throw away anything.

To complete the job and make it more professional, you can design some stickers with the operation explanation:

  No transistor circuit

 
 For the more simple version, we can recycle a DC charger capable of hold the two circuits:

   You can use a original Hall sensors female harness to connect the tester with the harness on bike. Thus will made the operation easier.

Thanks for that I just might make one or at least shall put it on the end of a long list of gonna doos.

Hi there.
Very nice and elegant solutions.
I´ll try them, but being a lego on electronic gadgets, I would like to know the resistance values and transistor type that could be used.
Best regards
JAP

You can use almost any transistor. I used a BCY70. The resistor value is about 470 to 1000 ohm.

Images have disappeared from this thread.  Did anyone have the foresight to make copies of this before the images went missing?

I want to build the tester, but am very challenged when it comes to electronics. I need to match the wires in the first circuit diagram with the wires in the photo of the tester. I'm interested only in the ignition timing bit - ignore the ABS part. If one were to number the wires in the circuit diagram from left to right, 1 - 2 - 3 - 4, please match them with the red, green black wires in the photo.

Thank you

Paul

The photo with the tester using the red-green-black wires is the transistorized tester and you are asking for information on the non-transistorized varient of the circuit. I presented the annotated photo on the non-transistorized unit based on your instructions.

   Hi.

   Here you are the colors of the wires for the transistorized version.

   You must consider that you need to use the same green wire to check one Hall sensor and then change it to the other.

Wonderful! I get it - this I can do. Thank you very much.
