The application of this versatile tool is based on two basic points: Different types of ignition systems have the same basic components with signals measured being generally similar in nature and magnitude. No disassembling of ignition components are required. (This avoids accidentally introducing, or correcting, poor contacts in the system, which may further confuse and delay resolution of the unidentified problems.) The power-sports vehicle industryâ€™s most recommended problem-solving ignition trouble-shooting tool includes the following measurement options: Primary low tension / peak volt 10, 40 or 400Vpk scales – use the RED & BLACK silicon tester cables to measure primary signals between the ICU and the power supply (battery or charge coil), timing pick-up (pulse coil or hall sensor), ignition coil and switches (key, emergency stop, footstand, throttle). The silicon tester cables are resistant to damage from hot engines or exhausts. Also included are insulated crocodile clips and special PROBULATOR back probes that allow easy connection (without damage) to in line cable connectors. Secondary high tension / peak volt 10, 20, 40 kV scales – use the caliper to measure high voltage between the ignition coil and the sparkplug. Use the +/- switch to determine the polarity of the high voltage signal. Normally single output coils have negative signals and dual output coils have negative and positive signals. Spark scale to measure the consistency of the high voltage current signal and to determine misfires. The signal strength can be varied for display purposes. Spark strength of different cylinders can be compared. The dual displays allow simultaneous measurement of two different ignition signals. This allows you to narrow down between which two points the problem lies. The instrument is powered by an internal rechargeable 1,5Ah NiMH battery that provides 6 hours autonomy. Recharge the battery with any 12VDC source, such as a vehicle battery or 12VDC adapter. The standard kit includes the instrument with rugged rubberized protective and mounting holster, combination spark cable caliper pick-up with silicon lead, stick-coil adapter, silicon test lead set with insulated crocodile clips and Probulator back probes, 12VDC 2-meter (6 Â½ ft) power lead and instruction manual & quick reference guide all packed in a custom carry case.
