Default Need some quick help - Crank Sensor

Can someone please verify for me that on the 1990 Bonneville on the ICM connector at pins G (18x signal) and H (Sync signal). That the values are supposed to be 5v for G and 9v for H. I could have swore that I read that the voltages were supposed to mV values. I installed a new crank sensor after installing some jumper leads on the harness and was not getting any voltage from the crank sensor. Now that I have replaced the sensor and the engine is running (not quite a smooth as I think it should be) I am getting voltages that I think are high.

Nothing that I remember is mV, should be V only IIRC

Correct.

Unless you've got an o-scope and you're watching the waves... you're going to see V.

Thanks for the input. Engine is running fine after several test runs.
