Hi guys,
can any one tell me if the sender on the end of the camshaft puts out a pulse per revolution or a constant voltage or what? I'm wanting to know what signal the sender puts out.

I'm driving a 1992 Nissan Safari with the silvertop TD42. Being a safari the main system is 24v, and I am sure the instrument cluster is too because A I havent found the reducer yet, and B the voltage of all the panels, windows, lights, and everything else is 24v.

Cheers, Dylan
