Tach sensor on 6BTA

Just wondering where the tach sensor(magnetic pick up) is on a Cummins 6BTA(330 Diamond). I took a very abbreviated look yesterday and it was not immediately obvious.

On flywheel housing. Looks like a threaded stud with four wires coming out of it, towards left side of engine. Two windings, one for air heater control, one for tach.

John,

It is more like 10 or 11. It is also somewhat obscured by the aftercooler, but you can see and reach it if you know what you are looking for.

Time to change your fuel filter. The deadman red needle is in the red like at 11 oclock!
