Cummins tach sensor wiring.

Provide a smooth reliable tachometer signal to your cummins converted truck. Start engine and check gauge for proper operation of tachometer. My 1997 dodge ram with it s 12 valve cummins diesel engine has had a strange intermittent problem that s gotten worse. 8912 flywheel gear sensor dual output x 16tpi 2 1 2 long.

Hi all i have a cummins 6bta with an alternator driven vdo 4 tach. Model 8912 is a dual output four wire magnetic sensor. Calibration and adjustment the tachometer is factory calibrated to 3 full scale accuracy. The swaphelper is an electronic signal conditioning device.

I installed a faria unit actually 2 and got no reading. The tachometer is intermittent random. I measured about 3v ac at the signal wire. Provision has been made for finer adjustment if.

There appear to be 2 harnesses red black wires in 1 green white in the other. I am replacing the tach because it will intermittently stop working. When wiring is complete connect power. It fits a x 16 tpi threaded hole and is used to sense the passage of gear teeth.

Having a little trouble with the wiring on this need a simple wiring for dummies course. Cummins will sell the sensor but they don t have wiring diagrams available. If not check wiring. Is there a simple diagram or better yet a picture on how to wire this.

You have to keep the cam sensor and the crank sensor wires seperated until you get to the sensor then wire them together if you run them together they will pick up signals from each other and cause problems the shielding on the wires is crap i think you can wrap one in aluminum foil but that is a pain and doesn t look very good.
