For use on vehicles and power equipment equipped with a high energy ignition system. Value is at the core of the OTC tool and equipment portfolio. Whether it’s a simple repair or the most complex drivability concern, these award-winning tools universally solve problems faster, and at better value, than any other product line available. Whether it’s a specialty tool or unique piece of service equipment, OTC provides top solutions to modern automotive service challenges while increasing technicians’ productivity and shop profits.

Review: Awesome tool, more important than you might think. - Excellent tool, I don't even consider using a screwdriver or additional spark plug to test coils, a real test anymore. Coils sometimes like to get weak over time, and cause occasional misfires. You can't really test if it's 20% weaker than its supposed to be. It will still appear to be a good spark. Unless you use the OTC spark tester, it requires the coil to output a much higher voltage. Similar to under high load conditions. Sounds like I'm trying to sell this tool, but it saved me a lot of time today on a Ford 5.4 with 4 coils that didn't pass on the tester. They all had decent spark but not enough apparently. Replaced all 4 of the ones that tested bad, and now it runs great. There's no other way I would have known that. The only issue I've had with it is the end that snaps into the spark plug wire kept unscrewing over time, a little loctite should keep it in place though. Also the porcelain can get dirty, I use brake cleaner and a clean paper towel or q-tip to wipe it clean again. I bought this about 2 years ago, it's helped me a lot but really saved me today. I paid $13.84 here on desertcart. Paid for itself over and over. Edit 2021: the clip fell off recently, since it's really only hung by a small metal tang. Problem is, the spring flew somewhere and now I can't use the clip anymore. In order to ground it, I have to attach a small jumper wire to it now. Which I had to do that occasionally anyway, since cars have so much plastic. I'll probably find another spring eventually, and cut it down if I have to.
Review: Nice tool - I’m not a professional mechanic, but I pretend to be one. We’ve all done it before—using jumper cables or vice grips or any other means of grounding out a sparkplug to check and see if it has spark. Well, that’s basically what this thing is. I’ve only used it once (on a ’96 Toyota with coil on plugs) and it worked like a champ. I don’t know if the shape of the porcelain and the gap it has to jump affects how loud the “pop” of the spark is, but you don’t even have to see the spark to know it’s working—you can hear it. I know there are some comments about this unit not working with older style ignitions, but let’s be serious. If you’re working on a 65 Ford, you probably just hold the spark plug in your hand and crank the engine to see if it’s working. We’ve all done it….at least once to our little brother. It’s a little on the pricey side, but as long as you don’t drop it on a concrete floor or throw it against the wall, it should last you many years (or 100,00 miles, whichever comes first). Very happy with my purchase and I wouldn’t hesitate to buy again.

*by E***1 on May 7, 2013*

I own an automotive repair facility that employs 3 other technicians and I have been using spark testers for over 30 years and I have tried them all: 1. The plastic encapsulated ones (not reliable or accurate) 2. The "In Line" type - NEVER - NEVER USE THESE!! It only takes around 10,000 volts to "light" those up - but todays cars need upwards of 50,000 volts so you'll have a "light" but not enough volts to fire the spark plug. 3. I have had 2 OTC 6589's in my box for 20 years - they ALWAYS work AND tell the TRUTH! Yes, I have played around with the others and ALL OF THE DIFFERENT STYLES OF THE FIRST 2 I LISTED HAVE CAUSED ME TO MISS A DIAGNOSTIC. (Hence - cost me productivity time & money) But, when I am in doubt, I grab my OTC and PROVE IT! I NO LONGER USE OR ALLOW IN THE SHOP ANY OTHER SPARK TESTER THAN AN OTC. When I am diagnosing a V-6, V-8 or V-10 motor, I use 2 of these at the same time - one on each side of the motor. Sadly, I dropped one and it being porcelain - it broke (just like a regular spark plug would) So I just ordered 2 more today to keep in my shop. By the way--- the KD 2757 that "LOOKS" the same as the OTC one DOES NOT!!! They changed the design and it is now "plastic encapsulated" and not as accurate. (Same design as the KD 2756) Yes - the OTC is more expensive but this is truly a case of " YOU GET WHAT YOU PAY FOR!" Update: Something I forgot to mention - the clips on these are as heavy duty as they could make them with the amount of material they have to work with. I don't use the clips on the tester itself (yes, they break) I use a 3 foot jumper wire I made out of common "lamp cord" with alligator clips on each end. (it's flexible, heavy duty and rated for 25 amps) (also see: Kastar Hand Tools (KAS1138) 2 x 30' Magnetic Retractable Test Leads - 10 amp rating) I clip one end of the jumper wire to the spark tester clip and the other end to the CLEAN Negative post on the battery - not any metal on the engine itself. If you don't "KNOW" that you have a good ground (rust, corrosion, bad ground from battery to engine block) then you could make a false diagnostic not due to the spark tester operation but because you didn't have a good ground path for the current. Whenever I am testing electrical, I NEVER ground to the frame or body - I always run a jumper wire to the battery negative post - and make sure the negative battery post is clean!
