Quick Links


The TA100’s unique and proprietary technology allows the user to perform quick and reliable diagnostics of non-starts, misfires, fouled up or damaged spark plugs and/or spark plug wires, by comparing digital read-outs of the spark plug voltage between cylinders on engines using conventional distributor/ignition coil, DIS (Distributor-less) or waste spark and magneto technologies.

Simple to use, the TA100 requires no special adapters, cables or a scope and is equipped with a large digital display that shows spark plug voltage, RPM, as well as Min/Max readings in real time.
