View Full Version : Diesel-engine tacho recommendations ?

02-25-2007, 07:27 PM
I have a pair of 4-cylinder turbo-charged diesels in my motor-cruiser.

The tach sender is a half-wave output from the belt-driven 3-phase alternator installed on the engine.

A simple set up but not particularly accurate, due to belt-slippage upon engine warm up, among other deficiencies.

Has anyone retro-fitted a more accurate tacho-plus-sensor combination on a diesel ?

Would welcome some help on this subject.
