Which of these tools is used to perform a relative compression test?
A) pressure gauge
B) scan tool
C) inductive ammeter
D) All of the above
Relative Compression Test
A quick way to identify a weak cylinder by cranking the engine with an inductive ammeter on the starter circuit. With a lab scope, cranking amperage can be graphed and correlated to a particular cylinder. A cylinder with low compression will draw fewer amps than a cylinder with higher compression, which will show on the graph.
Inductive Ammeter
An instrument used for measuring electrical current without the need to make direct contact with the conductor.
