Abstract
An ignition circuit tester including a pick-up coil assembly for inductive coupling with and location closely along a circuit element to be tested, an amplifier circuit for amplifying a signal picked up by the coil assembly, and a meter to indicate the signal.
Claims7
An ignition circuit tester comprising a pick-up coil assembly selectively locatable along an element to be tested for indirect coupling thereto and generation of a signal in the pick-up coil assembly corresponding to the signal in the element tested, amplifier means connected to the pick-up coil assembly for amplifying the generated signal, and a meter connected to the amplifier means output affording a visual indication corresponding to the generated signal, said pick-up coil assembly comprising a conductive housing having one side open, a coil proper located in said housing with its axis straight and extending along said open side of said housing, and non-conductive material embedding said coil proper in said housing to protect the coil proper without effectively detracting from the inductive coupling, said housing being grounded to effectively shield said coil except from the open housing side.
