Otc 6589 Electronic Ignition Spark Tester (Auto Accessory) 4140

Review for otc 6589 electronic ignition tester

Price was $21.04. My old truck wouldn't start and i was having a hard time determining if it was getting fire. After putting this little dude between the spark plug and the plug wire i could see that it wasn't getting spark so i knew to look elsewhere for the problem. This spark tester is well made and will last forever.

Lisle 20610 Inline Spark Tester (Auto Accessory) Review

Review from A. Donna, South Australia 
I Have 4 Old Tractors Dating Back To A 1953 Ford Golden Jubilee. These Are Working Tractors On Our Little Ranch. As You Might Expect I Never Had Enough Them All Working At Once. This Little Spark Tester Has Been In Constant Use For A Couple Years Now. I Wouldn't Call It Good But Rather Invaluable!

Also The Probe Is Too Short To Reach The Connector If You Also Have A Metal Shroud On The Plug Wire. Like On A Vanagon. In Short Sell The Vanagon If You Want To Use This."

As A Small Engine Technician I Use A Spark Tester Every Day. I Love That It Has A Straight And 90 Degree Ends That You Can Flip Around To Suit Your Application. The Leads Are High Quality And The Rubber Coating Is Tough. The Same For The Plastic Casing Around The Element Which Is Also Large And Easy To See. This Is An Automotive Tester Intended For Long Spark Plugs So I Did Have To Trim The Boots Down To Fit Onto Chainsaw Spark Plugs But Thats A Quick Fix. This Is A Great Tool And I Believe It Will Last Quit Well With Daily Use.

F. Cortney, Dorset

Anyone With A Points And Condensor Car Needs This In Their Tool Box. Cars Need Spark Fuel And Air. You Can Assume The Air Now Worry About Spark And Fuel. This Will Define Whether You Have Spark. Don't Go Chasing The Carburetor When Your Points Are Scorched.

Best otc 6589 electronic ignition spark tester (auto accessory) in review

A must have tool in every mechanic's tool box. It has saved me hours and hours of trying to figure out where a misfire is coming from. I've had coil packs that would produce spark when grounded out on a bolt, but with this tool, they were totally dead. Swapped them out with known to be good ones and boom, problem solved. I've used it on several different cars and trucks and it has been a life saver. I use jumper cables to make sure i have a good ground so that a) the clip doesn't break as it is a bit on the flimsy side and b) so i have space to work. I'd buy this tool again and again.

B. Adrienne, Torbay says

I like it it works just fine

X. Morgan, New Jersey

Works well for quick testing spark capabilities on hei gm systems. Tests coil, distributor cap and rotor , plug wire for spark. Works much better than holding a spark plug against the block. You may not be able to count the number of sparks, but surprisingly you can hear a consistent : tic, tic, tic tic when the spark jumps correctly.

R. Joanne, North East Lincolnshire says

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!

Q. Olga, Sachsen-Anhalt

Purchased this tool as recomended from my automotive teacher. Works perfectly as it should. It was his recommendation for best quality for price. I expect it to last me virtually forever provided i take care of it when in storage.

S. Gilmore, Blackpool says

X. Carol, Wakefield

Simply solution for testing spark.

P. Guest, Kensington and Chelsea says

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 online store. Paid for itself over and over.

V. Guest, Mississippi

I have used other spark testers but this one is the best in my opinion. Great for trouble shooting ignition troubles.

H. Russell, St. Helens says

Used for testing high energy ignition (hei) systems. Works as expected, if spark jumps from the core to the shell, the ignition is in good health.

F. Moore, Victoria

I was working on a standard transmission and the clutch had to be depressed for the starter to engage, and i couldn't use a remote starter button. So i could position this where i could see it through the windshield. It helped since i didn't have my "turn it over" buddy.

D. Amanda, Berlin says

Chevy vortec engines need special equipment like this to test the spark plugs. It is cheap and reliable. Remove the spark plug wire from the spark plug and install it on the tester's spark plug. Clip the clip to a reliable ground, preferably a wire connected to the battery negative. See the solid spark when the engine runs. Use the information gained to determine if you have problems in the ignition.

N. Rowe, Bury

Worked perfect helped me find a bad coil on my tahoe
