MOTOCOCHESpark Plug Tester 2 Hole, Ignition Coil Tester 0-6000rpm Adjustable Frequency, Ignition Plug Analyzer Detector for 12V Gasoline Vehicles
Main highlights- Wide Range of Compatibility -- This tester is used to test spark plugs (12 mm diameter) for 12V gasoline vehicles, motorcycles, lawn mowers, garden tractors, scooters, snow blowers, boats and so on. A lot of times, spark plugs are the main cause of failure to start. This tester will confirm if this is the case and there will be no confusion. And to verify that the old spark plugs are still working before installing the new ones.
- Quickly Find the Faulty Spark Plug -- In the automobile ignition system, the high-voltage ignition coil generates high-voltage and the spark plug diverts it form high-tension ignition coil into the cylinder engine, spark between the spark plug electrodes will ignite the mixture. The spark plug tester can distinguish a good or bad spark plug by the strength of the spark. The automotive spark plug tester can simultaneously perform dual-hole testing and simulate engine work.
- Plug and Play -- Automotive spark plug tester can simultaneously perform dual-hole testing, more efficient and time-saving. Simple operation, plug and play. To establish a baseline, you mount a new spark plug on stud 1 and a test plug on stud 2, which will enable you to visually check whether you have the same sparks.
- ABS Transparent Safety Cover Design -- In the spark plug area there is a protective cover on it so that accidents do not occur. Transparent protective cover also allows visualization of test results. Variable RPM to know exactly where your plugs are failing. Made of ABS material for durability and heat resistance. Do not open the cover until the test is complete.
- 0~6000 RPM Adjustable Working Frequency -- Allows to set the working frequency in the range of 0~6000 RPM. The spark plug tester can also simulate the engine work and restore the car start, so as to better test the spark plug. You can test one spark plug alone and observe the strength of the spark by adjusting the frequency, or you can test both plugs at the same time and tell the performance of the old spark plugs by comparing the old and the new ones.
