my Name is Benjamin and in real life I am an engineer. For my Hobby I try to convert a small V-Twin to EFI.
I have choosen a BMW 12141435350 cam sensor, respectively the pendant 3049081 from Q1-Part.
Ist a hall sensor with short cable.
For testing I pulled off the connectors rubber boot. The wire Colors are red, black and White. So I assumed Vcc, GND and Signal.
Supplied with 5...12V with a lab power supply and with a steel gear in front of the sensors face, I get a nice squarewave on the oscilloscope (Fluke PM97).
Unfortunately the voltage is only ~0V to 0,55V and not dependent on Vcc. No 10:1 divider used on the scope and Voltmeter Shows the same 0,55V.
Why does it not go up to 5V, or Vcc.
Pullup and pulldowns in 0k5...10k range were tested with no effect.
Might the metal insert inside the mounting holt be another GND?
Any ideas welcome!
Thanks in advance.
