WebJun 21, 2015 · The main usage of using the +12V rail to bias the TACH signal is that it provides isolation between the +12V and the low level digital voltage signals of the control system. Three considerations are: 1) Fan wires can get pinched between chassis parts and shorts between the four wires become possible. WebTip: If your sensor is connected to a wheel with a large number of teeth, like a Ford 36-1 or a Bosch 60-2, and you’re losing the tach signal at high RPM, put a 10K resistor in line with the wire going to VR+. This will usually clear things right … WebMay 9, 2024 · The tach pin normally sits at approximately 2.5 v when not pulled down.
