@maycor1076 Thank you for the kind words. Yes, testing a coil with an
ohmmeter can have faults like you stated. However, when you test a coil
with an ohmmeter and it is out of specs that coil is defective. Another
more accurate test is with a lab scope. In the near future we will be
releasing the first in a very long series of videos showing how to use your
lab scope. Thank you for your insight it is greatly appreciated. Stay tuned
for the lab scope videos! Mark Hicks Wells Manufacturing L.P.
Don’t you have to apply dielectric silicone between the coil and module? Or
is the potting material by itself suffient?
please help me with my truck. i poseted a video. i am a dumbass
@nobleheight The seal between the coil and ICM in this case will protect
the connections. Mark Hicks Wells Vehicle Electronics
@nobleheight In the beginning of the video we showed the rust and poor
connection between coil tower and ignition wire, this killed the coil by
forcing a higher than normal output. Mark Hicks Wells Vehicle Electronics
Did the complete lack of secondary ignition cause the rust to form on the
terminal or did the rust on the terminal cause the coil to have an out of
limits resistance reading? Which caused what? The chicken or the egg?
@nobleheight The rust comes from the ignition wire terminal, the coil
towers are aluminum. The rust occurs due to a defective boot or lack of
silicone to help seal the boot. I suggest watching our odd misfire video
for a more in depth explanation. Mark Hicks Wells Vehicle Electronics
This video is very informative and useful. It does not show me how to test
coil, ignition control module, and other parts. All it shows is a regulat
inspection and replacing almost all the parts for the ignition system.
Testing coils resistance is not accurate because you can still have
resistance within specifications and still be at fault. Replacing the parts
shown in this video most likely guaranteesfixing an ignitio problem because
almost every part is being shown to replace.
@sks123ify As long as the ignition key is turned off, you will be OK. Mark

What killed the ignition coils to begin with?
when your ohming the ignition coil do you have to disconnect the battey?
