Rarely see a BMW in Montana, US. Delco Remy and Auto-Lite coils don't have that feature. Thanks for the refresher on coils. Plenty of old vehicles & machinery around here.
I had this coil on my w123 280ce mercedes and when it failed, the circle cap (your question) had a blow out and some oil leaked from it so I imagine its a safety valve and check valve
Ohms testing is great but temperature effects things massively hard wiring is by far the best choice. I used to reflash ecu's and temperature would effect that to the point they wouldn't reflash properly. Just a thought anyway happy youtubing
You can also add 12v to the positive post put the ht lead in the coli with a spark plug in the end run a jump lead from the negative from the battery to the plug and and connect a wire from the minus side of the coil striking the spark plug it should spark if it doesn't coil is no good
@@XarlioG60 By performing the battery test you should see a small spark from the spark plug. Keep in mind that the bigger spark will be produced when touching the wire that connects from the coil negative to the battery negative :D You can take a look at the video below, it was already tested in this channel: th-cam.com/video/oc941J0wh0Y/w-d-xo.html
I am thinking a little hole in the coil was to put the wires in place. It's probably where the clip fit into. But that's just a guess because I have no idea what are the coil came from or what it belongs to.
When I put one probe into the output terminal and one against the outside of the coil I get a 7.50 reading, which is the same reading I get if I go from a primary terminal to the output terminal. Does that mean the coil is bad? My motorcycle seems to be running ok, but if the coil is bad I should replace it.
Yes that tells us how to test the resistance. But why oh why is there no video on TH-cam that tells us how to test the VOLTAGE of the coil?? Very annoying.
Great video but there so cheap it's almost quicker to just swap it anyway?? If you have doubts about a old coil chances are it's been on the engine for a while so just change it.
Not nowadays , especially for older vehicles. Just paid 100$ for an old/new (in box unused but on the shelf for years) Bosch coil (yes, you can certainly still buy a no-name for 15$ + shipping but it’s pretty common to buy a dud coil and think there’s something else going on electrically and spend time/$ trying to chase it down). And a video like this will help you eliminate a bad coil before going to the next possibility .
Now we know what Dracula does in his free time ! Great video Dracula !
😂😅
Bla bla
Excellent video, straight forward with no hype. Thankyou for posting
I have a couple of equipments that use coils in the engines. Now I can test them. Thanks again.

Thanks for the comment! Of course, BMW is more for Europe. And old cars are for fans, for the soul.
It is for a condenser to keep out static interference on the radio
Thanks for the crystal clear video
Thanks for the rating!
Thanks for practical video.
Excellent video.
well done,thanx alot for such wonderful lessons.

That's a sure sign it's failed I'm a marine engineer and see these a lot on boats leakage is a sign it's on its way.
I got 608 on all tests..... Is that good or bad?
Very good
And helpful teaching
Thanks a lot!
Is the hole for pcb cooling oil like Lucas had?
Is there continuity between the pos and negative pins?
Mine is reading 5950 & 0.6 ohms
Should it replaced?
And what about a coil ages? .... Which internal components start to go?

They showed the temp
Bro do you have the product link

How much the spark should be visible in a room completely dark doing 12V check?

The coil was on a BMW, and the hole is a fuse, in case the coil fails

Bad. Should replace. It's case should not have an Ohm reading like that.
Ahhh. Now I bet the other reply is correct. Fuse holder?
Its for a supresor for radio
🔥👍
aren't those readings low? shouldn't. it be 1.5 ohms on primary
Yes that tells us how to test the resistance. But why oh why is there no video on TH-cam that tells us how to test the VOLTAGE of the coil?? Very annoying.
👍 👍 👍!!!
Thanks! Slava Ukraini!
Closed Captions please? Thanks for sharing, - take care
Thank you very much for your comment!
That's a wire terminal Lock
Hello, whats the little hole for?
Hello! If the ignition module is defective, a fuse will blow in this hole in the ignition coil. This will protect the coil from explosion.
@@helpfromthegarage1677 whoa, cool! And where can i get this fuse? Mine always had an empty hole for as long as i can remember. Thanks!
As far as I know, it is impossible to change this. If there is no plug in the ignition coil, then the coil must be replaced.
@@Tenkaichibudokai22 🤣
1,2,3 ignition coil ah ah ah!!
😂
