The OptiMate IgnitionMate TS-91 is a professional, commercial-grade diagnostic tool engineered explicitly to troubleshoot all variations of spark ignition systems. Fast, high-voltage ignition pulses can permanently damage or yield inaccurate readings on standard digital multimeters. The TS-91 solves this by using specialized circuitry to safely capture, translate, and dynamically display both low-tension primary and high-tension secondary ignition signals. Recommended across the powersport, marine, and automotive industries, this tool allows technicians to analyze active engine components without disassembling factory wiring, preventing the accidental correction of poor contacts that can stall diagnostic troubleshooting. Features and Benefits Comprehensive spark system compatibility — Seamlessly analyzes all major types of ignition designs, including AC-CDI, DC-CDI, transistorized, magneto, traditional ignition coils, and contact points. Dual LED bar-graph displays — Features twin vertical displays containing 40 high-brightness LEDs each, allowing for immediate, real-time simultaneous comparison of two different electrical signals from the same cylinder. Non-intrusive component testing — Captures vital engine signals using premium exterior sensor leads and calipers, removing the need to strip wires or pull apart harness assemblies during active diagnosis. Secondary high-tension peak voltage tracking — Selectable scales of 10 kV, 20 kV, and 40 kV allow precise high-voltage tracking directly between the ignition coil and the spark plug using the included signal caliper. Dynamic spark current consistency scale — Isolates and measures the physical consistency of the high-voltage spark current to easily identify intermittent cylinder misfires and compare spark strength across different cylinders. Primary low-tension peak voltage monitoring — Selectable measurement ranges of 10V, 40V, or 400V peak let you probe primary signals between the ignition control unit (ICU), power supplies, pulse coils, hall sensors, and kill switches. Rechargeable cordless autonomy — Powered by an internal 1.5Ah NiMH battery that delivers up to 6 hours of continuous continuous cordless runtime; recharges via any standard 12V DC power source or vehicle battery. Rugged workshop construction — The main diagnostic instrument is housed in a heavy-duty, impact-absorbing rubberized protective holster designed to handle mechanical impacts and drops in busy shop environments.
