ABSTRACT:
A circuit tester for vehicle fuel injectors uses light emitting diodes which are individually illuminated by the pulse of electrical energy sent to each injector while the vehicles's engine is operating. The housing of the tester may be provided with a longitudinal slot in which a magnetically attached, moveable support for a magnifying lens is positioned. The lens may be positioned over any individual diode to allow viewing from a distance while performing engine tests, and a further moveable polarized filter can be positioned across the magnifying lens to improve the viewing capabilities.
