hallsensor is ok. with the pullup, but not ecu there is 12v from it when is not in hole, and 0v when it come to hole.

But on the tach on relayboard there is only 3-4v with pullup. less without pullup. Why...?

I did that, no difference. But I begin think about ground...what pins should be connected? (cable between MS and relayboard)

all pins 20 to 37 is connected (db37 to db37)

2,7,8,9,17, 18,19 are connected.

but not 1,3,4,5,6,10,11,12,13,14,15,16

okey, I will try that.

The ignition module has an internal pull-up to 12V, whereas your MS-II on v3 board probably has not, unless you have installed one. So, have you installed a pull-up resistor für die Hall signal input?
If not, install one (1K resistor between 12V and Hall input) and give it another try!
Are you ...

I just making a new topic. I have a problem with my hallsensor. I shall run with MS-II v3.0. But I have not yet got rpm signal.

when it is wired like original to ignition module, it give 12v pulses. But when I hook off the wire who goes to ignition module, then I got no pulses. The hallsensor ...
