This tool is a magnetic field detector . It will detect magnetic fields on fuel injectors , spark plug coils , or starter solenoids . It will pickup the fields of any magnet . It is quite useful and inexpensive and works on A/C or D/C systems . 6/19/23

[@endurofan9854]

thanks bro, been doubtfull about it first, now i can say it really is

[@thestonedbud]

Me trying to find mine

[@joeycronan2652]

I had a misfire on cylinder number 2 and 7 on my Dodge ram. Replacing both coils didn't fix the problem. Removed the spark plugs and the electrodes were completely worn away. So a cylinder misfire isn't always a bad coil. Start with the most inexpensive thing first! Luckily the auto parts store let me return the coils

[@kmk1195]

saved my life but i used the commercial electric tester not matco.. best way to test coils by far. 60 seconds to test all 6! 10/10!

[@sayyoulovesatan666]

Those have been around for a long time…most electricians use them everyday.

[@SicknTwistedx]

Yes sir we do use them but can’t rely on them like a multimeter/tester

[@dragan3290]

I bought about 20 of these for 1 dollar AUD! I gave some away but I find that this is the quickest way to test ignition coil! Btw its just an AC voltage tester .

[@brianschrop1368]

That's great but u don't know forsure if it's the coil, could be wiring/connector or module. So u still need to swap some coils to c if it changes cylinders. I mean most common is the coil but I've seen it be the wiring twice. And I'm a HD diesel truck tech and only worked as an auto tech for a few years.

Thank you for this vid. It worked for me and replaced coil and away we go. Used the Harbor Freight Ames brand light. Worked like a dream.

Awesome, yes there are a lot of brands, it is a cheap tester to get an idea if spark is there or not.

I just pulled out all the spark plugs from my Mazda 626. Only two were oil fouled, the others in good condition

[@Chris-em2qc]

I didn't pull the coil out, cuz it's confusing. All the wires have to be labeled and put back perfectly back on the coil

Make sure you labeled each spark plugs wire with a magic marker, or tape, or your in for trouble!!

Cool. I have a lite that flashes when put near wires and plugs coils. But still those wont tell everything about coils but i still like

[@markh.6687]

I, of course, have to have one of those testers that never even flickered on a just-installed NEW coil, let alone the old ones on my '03 Toyota Corolla. My tester is marked "VoltAlert 1AC-D, sensitivity 90-1000 VAC". It does work on my home's electrical outlets. What brand did Nuts and Bolts use?

[@bryancarleton6915]

Or unplug each coil pack and go by the tone of the engine, if it gets worse the coil is good if it doesn’t change then the coil is bad

[@leesin2me]

Sometimes the connectors' plastic becomes very brittle. So it's best to only break the one connected to the faulty coil instead of all of them😅

[@Zoomzoom120]

Yeah then you end up changing coils that didn't need to be changed

[@YeakZa]

Unplug coil pack does not comfirm bad coil. We only know that one cylinder is misfiring. It might be coil, spark plug, injector, low compression or blown gasket. Method in this video can tell coil is not working.

[@firstlast---]

Great way to ruin a driver in the pcm. Dont do this on a modern car

[@YeakZa]

@@firstlast--- absolutely

[@elara680]

I use to use the timing light on the spark plug wires to see if the current was consistently flashing or if it was missing every now and then. That told me if my spark wires were bad.

[@endurofan9854]

this item seems to work similar to the hall effect clamp of the timing light

[@CadillacDriver]

That won't work if the coils aren't on the plugs.

[@gener.1253]

That works on a dead coil but not one with carbon tracking down the side of the plug

Is that just a outlet tester for power

[@trewten5579]

can you use the same tester for outlets? or is this specific for cars?

[@NutsandBoltswithTone]

It's only for ignition coils

[@deidrequeen3288]

Its the 3rd coil as well. Its barely working. Plus that motor is running too rough to be misfiring on one cylinder

[@selwyn13]

Can coils also be tested similar to this w/ a multi-meter by putting the black lead on the frame of the engine and touching the red lead just like u did here w/ each coil?

[@NutsandBoltswithTone]

No

[@stevenyazzie9159]

Wow i hope that really works.. been having a miss fire for about a month trying to figure it out

[@NutsandBoltswithTone]

All this is is a quick way to see if the ignition coil is firing. You can swap the coil to another cylinder and see if the misfire moves to that cylinder.

[@thecarfixchannel3046]

good, but is it the coil /wireing/or the PCM?.

[@NutsandBoltswithTone]

Well you have to diagnose that, this is only to see if your problem is spark, it is a simple test to see if spark is the direction to go

[@middlecrossranch3977]

The only thing this tool will detect is if the wire to a coil pack is live. It will not detect the functionality of the coil pack.

[@rickchambers73]

Retired Catapiller Heavy Equipment Mechanic. USELESS if the spark is leaking from boot to cylinder head. Many ways of misfire

[@CadillacDriver]

Can new coil packs also stop the shaking in the engine due to a misfire?

[@NutsandBoltswithTone]

If the coil is the cause of the misfire

[@NutsandBoltswithTone]

Not sure there is much you can do. Does it do it on every car

[@K_spawn]

Dude take my advise! That tool is not 100% accurate, sometimes the problem is vintage leaked and the tool will pick it up as a good coil because technically the coil is working, it's just the voltage not getting to the spark plug

[@NutsandBoltswithTone]

Oh yes I'm aware of this, this is just a quick test to give me a quick direction. Thanks

[@scottsmadis9111]

Will it work by touching the plug ? My car has 2 coul packs that run 2 holes each ?

[@NutsandBoltswithTone]

you want to touch it around the top of the coil, maybe at each side of where the wires are and this is only a quick check that does not always work.
