I have had spark problems and checked my old Lucas coil against a newer black one, and against an unused new Beru. It was amazing to see the highly unstable results in the old Lucas, the newer black one reading too high on the secondary winding, and then the fresh-out-the-box Beru reading totally consistent results no matter where the multimeter leads were touched.
This was exactly what I needed. My VW 1600 cc engine for my Sand Rail ended up having a thin corrosion layer on the coils negative side plug. My testing with an ohm meter helped me to identify the problem and your tips to test a spark at the plug confirmed the coil was still good… Thanks 👍🏼
Hey Slade, Thanks for the detailed tutorial. I was having an ignition problem that I narrowed down to my Bosch blue coil. I followed your guidance and all checked ok, but still had a problem. I tilted the coil on the same angle as it is mounted on the fan shroud. Voila, it failed the primary test. I tested it multiple times as I slowly rotated it on its axis. It passed sometimes and failed sometimes. Please let your subscribers know to check it in an “upside down position” . It made a difference in my case. Purchased a new coil. Thanks again!
Hey there, appreciate all the VW beetle videos, just wanted to mention that the reason why one of the coil secondaries are showing 19k and then 1 is because you had the multimeter range on 20K Ohm, and the coil is going from 19k to past 20k so the meter goes into over-range and to get a reading you need to turn the dial to the next step or 200KOhm. I'm an electronics technician and Electrician so just thought I'd mention that. When a coil goes, the resistance drops, it never increases. But for re-overhauling the VW engine I am going to need all the help I can get man 😁
Hey Slade, great info on testing the Coils. Your 2nd short stubby coil that was reading weird , just set your volt/ohm meter up to the next level . From 20k to 200k. I think it was reading higher than what you set it at. Then you should get a reading on the meter. I hope this help. Keep the videos coming.
Good video! You are correct, the electronic ignition needs 3 ohms on the coil. I check my coils the same way. I had never thought about ringing it out to the case. You figure I would know that seeing how I'm an electrician. I do do motors that way.
Hello Slade. I have good resistance while testing the primary but absolutely nothing on the secondary side. My meter does not have an option to change the range. It’s an auto range high end fluke used in the electrician field I’m not getting anything out of the meter on the secondary. Not a beep. Could this mean a bad coil? Thank you
Hey Slade, Great and v v helpful video!! I just tested mine with one end being a test-light. I hope that its ok to use a test-light. Light illuminates when touched the negative gator and saw sparks but no sparks to be seen on the spark-plug 😢. Does that mean its toast?
Great video! I had no idea about getting the "zero" on the meter. My cheap Harbor Freight one is all over the place for a zero, but the readings seem consistent. I got a VW MG TD kit car from a family friend. It has sat unused since her grandfather passed away 6 years ago. Plugs and oil are brand new, he parked it immediately after servicing it. Some of the grandkids messed around trying to get it running, no luck. I have two coils for it, both show what I believe to be decent enough readings to at to spark. I have spark on both coils doing your test towards the end of the video. Any troubleshooting tips to go through for the condensor? And anything I should be checking on the rotor and cap? Everything looks extremely clean there. Just trying to figure out what's causing the issue between the VW schematics and the kit car schematics, it isn't too much fun
How is it possible that you look for short signals and the multimeter always reads zero even with the cables separated????? I think that in that reading you are not measuring resistance
you dont deduct the meter resistance on the second (high range) reading. the .02 would be 6860 - 0.02, not 6.86 - .02, so the reading really is not affected by the meter resistance on the high range reading, just the first, low range reading.
When you read on a 20K scale and you have a reading of 6.86, it means that you have a resistance of 6860 ohms. If you subtract 0.2 ohms from that, your result cannot be 6840 ohms.
But I wanted to know what how your test one it’s already installed in the car when your car won’t start how do you test the coil without taking out of the car? Nobody cares about testing your doing
Thanks!
Thank you very much, that was very nice of you my friend
@@SladesVWBeetle Wont those numbers be on the wiring schematic to denote pos and negative?
Thanks!
Thank you so much for the donation Jim! That was very nice of you I truly appreciate it.
I really appreciate these step-by-step videos. It's helped keeping me out of the auto shops and saves me a few $. Thx
The last part testing with spark plug and battery was very helpful. Thank you

Hey brother, i want to thank you for this video! You have taught me something i didn't know before! Thanks again, great video brother!
can you do a video on testing the distributor points and condenser and electronic ignition? great video btw thanks!
That’s a very good idea! I will do that in a very near future. thank you for being here

i learned alot from you.. thanks
Thank you William!
Grate video sorted out my problem
Great information brother, definitely learned something here!
Thank you brother I truly appreciate that! I hope you have a very merry Christmas
a very good video on how to test those coils and if they produce a spark.
well done my friend.

Hi Slade, love you're tutorials. Very informative and easy to follow. I like doing test videos and get good feedback which makes it worth it
Very informative video !!!

Excellent video tutorial!
This is way more than cost effective and less wasteful than my rule if it's ugly toss it.
Great video man good information right here
Thanks for the info love it.

Thanks, just what I needed
Where did u get your blue an white vw sign on wall
Those are not originals, they are re-pops. Honestly I buy most of them from Amazon if I don’t find them in local Fleatique stores.
Needed this information
I hope it helped!
@@SladesVWBeetle .It helped a lot my coil was bad even though I bought it 8 months ago.
Great video. 👍👍
great Video. So you tested it with the meter and then check for spark. Can you just check for spark and if you get a spark, then the coil is good?
Hey Slade, Great and v v helpful video!! I just tested mine with one end being a test-light. I hope that its ok to use a test-light. Light illuminates when touched the negative gator and saw sparks but no sparks to be seen on the spark-plug 😢. Does that mean its toast?
Aaah! Never mind! I had to turn off that bright chandelier 😅
Can you tell me what the box is that is attached to the shelid that enclose like a Squirrel cage?
Thanks!! interesting video.😁
Thank you Doug! It was actually requested so I did it at the last minute to help somebody

Thank you Jim!
Love the videos bro, would you send me the blue and white vw sign on the wall?
got a bad poping noise i have change plugs and wires put new carb still got poping what thank it is
You mentioned early in the video that once they get hot they break down. Do you mean like the idle would be weird? What would that look like?
On the second measurement that was 6.86 and you subtract meter resistance of .2. Wouldn’t it be 6.66 not 6.84?
I could’ve possibly said it wrong but paying attention. I was basically showing how to do it. Thank you for watching
Thanks. Great video. Much appreciated!
@@demRucks thank you so much for being here! I hope you have a very merry Christmas.
Where is mega ohms on the multimeter ?
I O M does not say one it says something weird and when I touching together it says 0000
How is it possible that you look for short signals and the multimeter always reads zero even with the cables separated????? I think that in that reading you are not measuring resistance
Nice how video

Yeah well mine has no numbers on it it has letters and looks like they're both positive so now what
When you read on a 20K scale and you have a reading of 6.86, it means that you have a resistance of 6860 ohms. If you subtract 0.2 ohms from that, your result cannot be 6840 ohms.
6.66, I came here to mention as well
Very informative but do you really need the gloves?
Don't use the "Tongue test method! " 🤣😅 JK!
😂😂😂
@@SladesVWBeetle lol, I thought you might see the humor! 👍🏻😁👍🏻
Bro your shaking! Dont sweat the small stuff.

why are are your hands shaking so much?
But I wanted to know what how your test one it’s already installed in the car when your car won’t start how do you test the coil without taking out of the car? Nobody cares about testing your doing
