I have a 1994 Cummins B-Series in my 1995 RV. But for the life of me I can not find where the Tachometer sender is. I am wanting to put a new gauge in, but my current one does not work. I have checked the alternator, but no luck. Can someone point me in the right direction..Please??

 

The tach sensor is mounted on the motor located down on the bottom of the block near the oil pan on the driver side of the harmonic balancer.It is easy to see from looking up from the bottom as it will be on the same side as the steering box.....Andy
