I was just wondering how do you check coil pack continuity? I just bought some and I got my multimeter out and put it to the continuity setting and all I get is a 1 displayed. Other numbers will appear but then it goes to one. I have seen that the resistance should be .8 ohms and other places like Haynes say continuity. So I was wondering what one is right? Also is putting the spark plug in the coil pack then touching it to a ground to get a spark an accurate way to testing them also?

 

Continuity means there is current going between the two spots where you touch the test leads. I think you're supposed to check them for resistance.

Ok, as long as resistance between terminal 1 and 2 on the coil is different than 0 you're OK. If it's 0 it's bad.

 

Ok ive been testing them out today and i get 1ohm on the 2k setting with red to power and black to ground and if i switch them i get .5XXohm with the red on the ground and the black on the power tab on the coil. I tested the ones in my car and i got the same results. I dont have any misfire problems. I also put in a spare plug and hooked it up to my car and grounded it to my block and i got a good purple spark when the car was running.

My multimeter aways shows a one on the screen, but if i touch the two test pens on the multimeter i get 0hms. I think the multimeter is working becuase the multimeter shouldnt be producing resistance when testing for resistance.

My question is does it sound like im testing correctly and are my resuslts showing resistance of a good coil?

 

sorry but your going to want infinite resistance on any ohmage of the coils. if you get "1" then that means its good, if you get some random number other than "1" then its f ucked.

 

I get "1" when power-to-power test lead and ground-to-ground lead. When I reverse the test leads I get a ".5". Does the reversing of the test leads matter?

I’m looking for a concrete answer because I am going to be selling 2 sets and I need them to work so I can have satisfied costumers.

 

Should I scan the page from the FSM? Will that quiet you down?

 

you were referring to the cont.. i was referring to the acutal testing of the coils. my mistake.

 

So, are y;all saying that if you change the coil packs, you need to check them? I am thinking of doing this today, but I don't have whatever it is that you would use to check the ohms... should i still do it?

 

get a multimeter. doesnt have to be the expensive ones i myself have a fluke one, you can get one at sears for $20

 

Nissan is full of poop when it comes to resistance testing in terms of coil packs.

Resistance, in terms of laymans terms, means the ohm number reading on ur ohm tester. Get urself an analog multimeter, and buy a 10 ohm and 1 ohm resistor from radioshack, and learn how to read ur ohmmeter/multimeter.

Anyway, I have perfectly good testing coil packs, that misfire. Wanna buy 'em?

Now, I've tested fuel injectors, and if they read infinite resistance(no continuity), they are toast (meaning zero continuity). But when it comes to coil packs, no resistance test can figure 'em out. The only sure test, is swapping them in and out of cylinders.

 

can you back that up please, ive never had a problem testing them out.

 

Short of sending you some coil packs that test "good"?

Last time I remember and the FSM, it's like, as long as they don't test 0 ohms, they're good. Based on max org members, they've said the same thing ( "My coil packs test good, but they misfire"). Based on me buying new coil packs, I'm right. Read some more.


Emmm. I work with electronics all the time, that work like **** under heat, but under coldness they test and test fine. That's when I replace them.
