Does it check for coil resistance output. Could it tell me if the ignition coil is good or bad?

It wont check resistance but it will tell how many volts are going through the coil a multi meter would give you the resistance.

It won't measure resistance. It will display the voltage output of the coil to the spark plug in real time measurements. If you have the specs you'll be able to tell if the coil is bad by the voltage its producing to the plugs. Even if the vehicle turns over but wont start, it will measure the voltage sent to the plugs on cranking. Keep in mind that bad plugs can alter the displayed voltage reading, may give the impression the coil is not doing its job.

Basically it checks ignition voltages. It will tell you what voltage each spark-plug has before it fires. It will tell you what voltage the ignition coil is putting out. It will give you RPM for any size engine:- chainsaw to V8 etc, but you will need a multimeter to measure resistance. Simple faults like broken coils can be determined by simple test gear. This instrument is for the devious faults. Mark

It only tells you the voltage going from the coil to the spark plug. It doesn't give you voltage from the stator to the CDI or from the CDI to the coil.

If your car uses this coil then yes. You could let people know what your car is (year, make, model, engine) and probably get more helpful answers.

I got one misfire from a faulty coil however i am running on CNG. The misfire would have not been felt if i was only running on gasoline as i have come to realise.

it only show examples like: 02 sensor, fuel too lean, throttle position sensor, cylinder 3 misfire....and codes for such. hope this helps...I made the necessary repairs, following the codes and description...and vehicle runs a lot better

It does not, the Tach reading is taken by the test lead from the negative side of the ignition coil.

No it doesn't. I've replaced a few individually in the past with no performance difference. After have half of them being two different types, I just replaced all 8 of mine with this coil.

I believe it will..Just plug it in and it will tell you the problem using a number.... Go to google and punch in the number and it will tell you. The thing is that if the car is working properly when you do the test , it won't show a problem]

I would check for spark first, a simple test for this would be unscrewing the spark plug while connected the putting the against a piece of metal if you see sparks consistently then the coil is good and it most likely is a fuel delivery problem. This one way work I would mesaure and make sure the screw holes line up otherwise you may need to machine new holes. hope this helps.

Very cool. Thanks. Im hoping its the temp sensor as I already replaced the element so far and thats the only thing left. Thanks again

I feel that the tester is quite accurate. If it is failing the battery, the battery is definitely junk. Sometimes it will pass a battery and the battery will start the car fine and is able to put out good cranking amps for a short time but then the battery may not have very good reserve capacity such as if the customer leaves their key on for a half hour the battery may die quicker than it should. But the age on the battery is a pretty good indicator for this sort of battery deterioration. It's a simple tester that works better than 2 others I have tried.

That's a question in need of a lot of definition. If you have a bad coil, or indeed no coil at all, then yes, this will make a huge difference. Night and day. if you're already running a full on crank triggered dual distributor race setup from a top fuel dragster, then this will be a step backwards. For the purposes of expediency I will assume you're running a more or less stock ignition setup on a more or less stock engine. Assuming your stock components are in good working order, then the answer is maybe. A good stock coil is not excessively lacking in voltage, but a hotter spark (within reason) generally doesn't hurt. I had a bad coil, and figured I'd spend the extra couple dollars and get the really cool sticker, because as we all know, the stickers are what really add the power. I figure mine brought me at least 25 at the wheels. All joking aside, adding this to a completely stock setup will not give you noticeable gains, unless your old one was bad. Invest in some good wires, good plugs, make sure those plugs are properly gapped and you have good electrical grounds to the body, and you might notice a few small things. With the things I listed I ended up getting better idle quality, and small (2-3%) gains in mileage, maybe slightly better off the line performance. Nothing really worth dumping a bunch of money into. For most folks, and most cars of this age, a good tune up and making sure everything is in spec is going to make much more of a difference. If you've already done that, and have the cash to burn, give it a try. It's not worse than stock. Then, put the sticker on and start blowing by Porsches.

Nelson, My coil was still good when I replaced my Pertronix breaker-less points. I am using the standard blue Bosch 043-905-115C 12v coil in my '82 Air-cooled Vanagon. If you "Google" that Bosch number you will see that the coil is available in many places online; the search may also help you figure out if that coil is the one you need...if you have a 12v AC VW...that is probably it...may want to verify if you have CA or Fed. emissions...seems like it makes a difference for the coils... I have Fed.. Good Luck! Hope you can get 'er to turn over!

Just because you have an o2 sensor code it does not always mean the sensor is bad. You may have a problem with the wiring or an exhaust leak

I dont believe it does. My car turns all power off to it when I turn the ignition off so has never been an issue for me.

I do not know. What I do know is the Accel Ignition Coil is junk. Like so many others, mine blew up causing me $200 worth of problems.

You need a code reader or you can buy a new coil and keep swapping cylinders till you find it. It could be the spark plugs too

Not really. Maybe check and make sure they didn't mix up a couple wires that go to your coils. Or if your coils are around 50 to 100k miles old ten they may be going bad
