Right voltage from AMM to ECU 700 1989

I'm trying to find out what is the right voltage coming from the AMM at idle.

Car is 740GL - 1989
AMM is # xxx 016
ECU is # xxx 561

I've seen several references for the Bosch LH 2.4 system ranging from 1.5 to 2V at idle. Mine is 2.6V. It is between ground and pin #3 at the AMM, or pin #7 at the ECU connector. If someone has measured, of can measure it - could you post it here?

Thanks.
