It is most likely a hose is disconnected. I am not sure about the non turbos, but if you have the digital dash that has the three little push buttons on the dash for distance to empty, and and the mileage reset, etc, then all you have to do to check the thing is hold in the top two buttons at the same time and then turn on the key holding them in for a few seconds then let go of the buttons and the dash will go through a self check mode and each part of the dash will light up one section at a time. Chances are though it is probably just a hose that's not connected.

What are the wires for on alternator?
There should be a heavy wire called the Alternator output wire, It carries power from the alternator to power your accessories and to maintain your battery. The smaller wires usually in a plug are either the alternator's voltage sense, Stator/ACurrent/Tachometer output, regulator/indicator light. or if its an Externaly regulated alternator they will be alternator Field, Stator/ACurrent/Tachometer. hope this helps

Working of AC tachometer?
A ac tach usually works off the AC signal of the alternator on a bus or truck. The alternator produces AC power that is rectified to make DC current to run the car, truck or bus. There is a TACH terminal or in North American buses more than 10 years old it is called a stator tap. The AC voltage changes speed (frequency) with the engine and the Tachometer reads that as a signal Early or inexpensive ones are actually run on the AC current.

was told there's a rev counter "unit" somewhere, Haine's manual has nothing, let us know if you sorted it? == Believe rev counter engine speed pickup is from the alternator. Had Rover 218TD with same engine, alternator went and rev counter stopped working. There were 3 wires to alternator, big thick red one, alternator light one and the rev counter feed. Hope this helps peter
