Ignition Coil Tester, OBDEMOTO 101 Automotive Electronic Faults Detector,Car Spark Tester and Voltage Tester Pen with LED Display & Two Batteries

This is a very good tool to have it eliminates a lot of work or guess work.

Good product. Will help you a lot. work perfect.I used to check all my personal vehicles. Before store don't forget to remove the battery from the test. why? any battery 🔋 with the time will start leaking acid and will damage any electrical component. will be nice for the future have one with CR battery the same battery use any watch ⌚ does battery doesn't have does problem. So far so good.

The media could not be loaded. Why did you pick this product vs others?:Decent price.Ease of use:Works well but there are no instructions. I went to the website and watched their video. The batteries do NOT fit tightly so be careful. Other than that the part was able to identify bad ignition coils/bad spark plugs. See my video.

Works, used it to test my coils.

I had a miss fire on my 2014 F150xlt 3.5L ecoboost on #5. Did not know if coil went bad or plug. Used the tester and found all coils were good. Replaced the plug and all was good. Easiest most affordable tester to use.👍

Works great! Thanks

Doesn't have clear English instructions, however it seems to work. It does feel physchally cheap but it will beep in rhythm with the firing rate to let you know a coil is working. You have to move the meter back and forth like a pendulum to test an Alternator

Great Product, works 💪
