Good day. The query is as follows: I have a 2018 boxer and I need to use the tension that the alternator runs on the witness cable. I was watching and it is a green wire that goes to the ecu. The problem is that instead of having a 12 volt signal when the alternator is charging, it gives me a digital square wave signal. Like a train of pulses. This is so?. Because the alternators of before only extended a continuous signal.
