Ok I need some help in understanding the proper way to test a coil pack.
I have a 97, 4.6l with the Ei system, 2 packs paired.
The book tells me to probe for secondary res across say number 3 and 5.
For primary resistance check between + and - inputs @the pack.
I searched out this problem on here but found a different way to check it (or at least I dont understand it anyways.
I quote... SVTRobG
You can check the resistence on the coils to see if any are bad.
Primary resistence = 0.55 ohms
Secondary resistence = 5.5 K-ohms
You check the primary by connecting your ohmmeter to the + & - terminals of the coil pack.
You check the secondary by connecting the ohmeter to the + on the terminal and the - on the spark plug side (there's a coil wire inside the boot).
If the coil pack doesn't test out to those specs it's crap !!!
The book tells me to check at the output on the pack 3 and 5 I get 13.26 ohms, the book says 5.500 ohms If I look at the picture in the book the ohm meter that was used shows the same reading as I am getting 13.26.
I have not done the other as I am not sure if it is ment to test between the + input at the pack to the output (wire) or else where. I just want to make sure I am not spending moneys for no reason.
I was gonna switch packs to see if my P0305 code follows but all my packs test the same.
Can some one shead a bit of light on my shaded brain
