Cummins tach sensor wiring.

When wiring is complete connect power. Model 8912 is a dual output four wire magnetic sensor. 8912 flywheel gear sensor dual output x 16tpi 2 1 2 long. I am replacing the tach because it will intermittently stop working.

The tachometer is intermittent random. Tach needle bumps when i switch on the key but no rpm reading. 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. I installed a faria unit actually 2 and got no reading.

There appear to be 2 harnesses red black wires in 1 green white in the other. I measured about 3v ac at the signal wire. Is there a simple diagram or better yet a picture on how to wire this. My 1997 dodge ram with it s 12 valve cummins diesel engine has had a strange intermittent problem that s gotten worse.

Provide a smooth reliable tachometer signal to your cummins converted truck. Having a little trouble with the wiring on this need a simple wiring for dummies course. Hi all i have a cummins 6bta with an alternator driven vdo 4 tach. Provision has been made for finer adjustment if.

T urn key ìonî ó tachometer pointer should move to ìzeroî. Start engine and check gauge for proper operation of tachometer. The swaphelper is an electronic signal conditioning device. If not check wiring.

Cummins will sell the sensor but they don t have wiring diagrams available.
