The mechanical limiter emits a pulse voltage. Analog meter will show something like 5 to 6 volts at senders. Digital meter will show the 2.X, 3.X pulse that averages 5 to 6 volts.
Found my notes.
At the temperature sender varied around 3 Volts. 4 Volts with lead disconnected from sender
At the oil pressure sender, varied around 3 volts either.
Don't recall if I used a digital or analog meter. My guess is analog.
