Monty almost certainly has diesel engines, which use a sending unit that generates a tach signal, or otherwise use a tach that counts alternator pulses (where the number of pulses per engine revolution is a known quantity).
As Rocco's original post points out, he has gasoline engines (Crusader 454/350's). Gas engines don't use a sending unit. If they use a point-type distributor, the tach signal is taken off the distributor side of the coil. If they use an electronic ignition and a single coil, it'll be taken off the coil; if electronic and spark plug mounted coils (rare in marine applications and never original on Uniflites), the tach signal will come from the ignition ECU. So, Rocco, don't go looking for a sending unit that isn't there. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "UnifliteWorld" group.
