Pull up resistor for tachmeter

Post by manolo.lezl »

Hello.

I read "0" from the rpm sensor.

My engine generates one pulse per revolution, and the vendor told me that perhaps I need a 1Kohm pull-up resistor. Anybody can give me a connection diagram for my RDAC-XG?

Thank you.

Solved.

A 1 kOhm resistor between tach signal from engine and 12 volts.

Regards.
