Definitions:

Circuit

In electricity, a path for electrons to flow from a source of higher electrical potential to a source of lower potential.

Timing Belt

A belt that synchronizes the rotation of the engine's crankshaft and camshaft, ensuring that the valves open and close at correct intervals.

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.
