HELP GAUGE REMOVAL /CUSTOM TACH

Popgun is correct, the pulse shape now looks just like in his video clip.



The difference is whether the engine is running whilst the wheel is spinning

There is a way to check the sensor with a dc voltmeter, connect the voltmeter positive to the blue wire and the negative to the white wire.
When the ignition is on and engine off the voltmeter indicates two voltages between the wires, either 9 volt dc or 7 volt dc depending on the position of the wheel.
When it is rotated slowly and stopped in various positions the meter alternates between these two values when stopped, if this happens the sensor works correctly.

Also the voltage is positive with respect to the frame ground but the white negative wire has + 0.7 volts ( v b/e of a transistor ) with respect to ground, so it is not grounded as i first thought and my wires connect to the instrument cluster, not the abs module.

Sorry about the jabbering on but someone might find it helpful I hope; cheers.

I like the waveforms you and PG have been providing.
