Cody, your videos are base knowledge, and if you are clueless like most people are some information is better than nothing. I'm old now and do homework every time I have to troubleshoot anything I'm working on. I say thanks for your information.

[@Desalt511voider]

This didn’t help me get to the very bottom of my problem (yet), but I learned a lot and I really appreciate you taking the time to be this thorough and share your knowledge. For someone just learning by wrench away in the garage your videos are really helpful! You do a great job sharing your knowledge in a way that is digestible to someone who is learning. Thank you

This video is freaking perfect. Good format, well presented. For me personally, perfect pacing also.

[@AuMechanic]

Hi Cody Re the plug caps, they have a resistor (rf noise suppressor) in them that fails more often then coils themselves IME as an mc mech. Noting also that in twin lead coils, since the circuit runs through both caps then if one is open circuit neither lead will have spark leading to 2 cylinders down not just the one. Which can be confusing to some since they might expect that one bad plug cap would only cause the loss of spark only at the cylinder the plug cap runs to not 2 cylinders. Hence why I test the plug caps first for any issues I suspect is ignition related or even fuel starving that the choke test makes worse, can often be done without removing tank completely.

[@TheMotorcycleMD]

Thanks for your knowledge bro! Appreciate you!

[@craigsturman6661]

[@abruptlyblunt]

@ i little heads-up to share, I took out one my coils on my bike when I didn't see that the little screw-in brass insert inside the cap which locks onto the the plug fallen out when i pulled the cap. When i put the cap back on I was in a hurry and didn't notice that the cap didn't lock on like usual, and when i took off riding after just a couple miles the bike started popping and dropping cylinders then lost both cylinders for that coil, when i tested coil the secondary side was completely open. Moral of the story, when you put the spark plug cap back on the plug i make sure and listen for the metallic clicking of the insert sliding down the threads on the top of the plug !!!

[@dfrontierit2114]

Thank you very much for your tutorial videos. It helped fix my Honda Jade 250 even when many other technician could not.

[@stephenhester9345]

For us in the back. We need a full view of the meter, how you are hooked up. What setting you use

[@Byronchi85]

He's using Ohms or resistance. He also explains what settings he's using by what results he expects to find in the video. I believe it was 5k for primary and 200k for secondary

[@Dr_Reason]

A coil is a "transformer" It makes a magnetic field with 12V and a couple of amps flow. Then when the voltage is cut off this sudden change creates a much higher voltage, but lower amperage, current potential at the output terminal. This voltage is so high it discharges through the spark plug gap to ground. The resistor caps cut this flow off after a few milliseconds or otherwise the longer pulse would cause a lot of EMF interference, messing up radio, tv and even the sensor readings on newer vehicles.

[@7x779]

Okay now how can you test a coil live on the bench to make sure it really Sparks under load? On the Old Automotive coils, you could ground the negative primary and body of the spark plug to negative on a 12-volt battery, then put a jumper lead and touch positive 12-volt to the positive primary terminal, and by touching and releasing it would Spark Testing resistance is helpful but there's no real load in the coil and sometimes a week winding will open up when a load is actually applied trying to make a spark So can be motorcycle coils tested this way?

[@scandinerdian1961]

Dude! I was just working on my bike trying to figure out the whole HT debacle, and your video just made it a thousand times more comprehensible. Thanks a bunch!

Hi Cody. My coils testd OK. Thanks . Can I clean my old regulator and rectifer. Would break cleaner work or a damp brush ,soapy water ,? Thanks .

[@Spitfireseven]

You did an excellent job here. The really crucial thing you did, as far as I was concerned, was pull the cap off the wire. I just made this discovery on my Suzuki Intruder. There is no way to get the cap through the frame to the plug. As I pulled off the old wire the cap came off. Low and behold there was a copper screw in the cap! This screwed into the coil wire! I never dreamed this was possible. It screwed back on too, Goooooood and tight! WOW!!!

[@thisguy1890]

Totally agree. It's always felt bizarre to me that the primary oldschool method for connecting the lead to the plug was : [woodscrew]

[@markman63]

Can you measure the voltage coming into the primary while cranking? Wondering if the spike will be too fast to be picked up by a multimeter

[@edgardocenteno4618]

You would need a peak voltage adapter and the spec is commonly 100+ pkv minimum

[@frankdavidson9675]

should be battery voltage with switch on it runs thru the condenser as points go open creating a magnetic effect and due to turns ratio a high voltage in secondary coil this is conn to spark plug wire and arcs on the spark plug

[@frankdavidson9675]

the voltage coming into primary winding is only 12 volts from key switchthe fact that the points are open allows current to flow thru primary into the condenser to gd this flow in primary makes a magnetic effect in secdonary coil as very high voltage due to turns ratio in secondary (like a step up transformer)this is conn. to dist and spark plug wire as point close this flow stops i happens very fast because points are grounded when they open the gd is lifted

[@brettdorrell8180]

Do the magna boots unscrew? I have a spark with boot out of head spark comes out anywhere near metal.when in the head the exhaust is cold?

[@Pynaegan]

So, what's the difference in the blue and yellow wires for the primary? My old coil has the blue wire coming from the "front" of the coil (where the two secondary wires come from) where as the yellow wire comes from the "back" of the coil. On my *new* coil, the primary wires are not preinstalled and instead, the blade connectors are unmarked and look to be the same. I'm uncertain of what wire to put to one or the other. Does it matter? (ain't trying to burn out a new coil)

Just watched your video which was great btw. I have a Multistrada 1200S Touring 2013 that has a misfire when warm The engine feels lumpy and you can feel the misfire. When I gun it, it pulls normally. I have checked the mfg wiring chart and it looks like the coils are the wrong way around on my bike to the wiring diagram ie the front cylinder HT leads are attached to the right coil, the back vertical cylinder to the left coil when the wiring diagram shows it the other way around? In your opinion, could this be the cause?

Insulation resistance testing is something you should consider, it can be a very useful diagnostic tool. Nice series 👍🏼

coil are coated with varnish so they do not short between turns you can not see this with ohms testing a suspect coil quick way i sub with a know good coil .

[@otooled]

@@frankdavidson9675 That's exactly what you are testing when you check the resistance (measured in ohms). If the insulation breaks down between windings and shorts out the original path creating a shorter path then the resistance will be lower because the amount of wire the current runs through is less. If the wire is degrading then the resistance is higher.

Dirt Bike Coil: I have a new coil, it is perfect, so is my old coil, I A/B'd them for spark, installed on bike, both great. The new coil does not read when testing the cap terminal (secondary) to ground, I've tested it with several diff meters lol, nothing, grrr. When I took the cap off thinking maybe the secondary coil lead to spark plug might be some carbon powder style, nope, just common strand wire, testing that exposed wire to grd without cap, reads about 3000 ohms, with cap on it reads absolutely nothing, but again, it works fine.. any ideas as to why I'm not getting a reading via the cap's spark plug terminal?

[@yveslegrand9826]

Beware, if you touch the meter wires when testing secondary in kohm range you may fool your readings. Your fingers resistance is about 10k..

[@anonimous2451]

There is a technique known as the "dead man" whereby you use the meter to hold one of the probes for you (some models, not all) thereby eliminating the ohm pickup of one's own skin touching the leads. This is a common occurrence for those without proper training in meter reading and testing. The harder you touch the leads the less ohm's of your skin. NEVER touch the tip leads of a meter, it's a bad habit to get into doing even with just testing ohm's.

A question; my spark plug wires (Honda Transalp xlv650) show the correct resistance, but will not give continuity on the meter. Is that a problem? Also, according to the manual, the coils should be tested at 20 deg centigrade, but that's impossible to tell. I left them inside over night, but they always show too low res on the secondary coils, however they both give identical readings. What are the odds of they really were faulty?😮

Did you figure it out?I’m having similar symptoms.

[@scandinerdian1961]

@@BigDreamsLilBike I never actually got an answer for it, however I've come to understand from my own experience, that no continuity in the leads does not equal them being faulty. And I'd say for the temperature issue on the coils themselves: if they both give the same resistance, they're most likely a ok.

Battery replaced, reg/rec replaced (it was faulty and sending positive charge through the negative lines), starter solenoid replaced, new wiring, new lights, new switches...the only things I haven't replaced are the points, coils, plug wires, and plugs.

Put the multimeter to the plug and cranked it and I'm showing voltage but it seems pretty low. TL;DR This vid taught me that I was testing the coils wrong.

You don't need a degree, just about a couple of brain cells is all that is required. Perhaps you only have the one brain cell which is where the problem lies! 😁😂

I think you're pretty good man I like you even though it's really long I learned a lot more than from these other fools this is dank from San Diego watch you're six and just be safe

Hello Cody! Great video! Something that I've always wanted to cure / fix on my 94 Honda Pacific Coast is that the headlight seems to pulsate at idle revs, and stops when I rev faster, and also when idling, if I turn on the turn signal, like the neutral green light on the dash counter blinks to the blinker... and it drives me nuts.... I feel that it's just a signal of an old bike... and that the wiring loom over time has corrosion and that's the result... a weak electrical system. I've tried cleaning many time the 1 ground wire I seem to find... but maybe there's more. Maybe you could do a vid on your perception of how to solve issues like these on old bikes! Thank you!

Check the wattage of the headlight. This can happen if a higher than specified bulb causes too much draw

[@steven-vn9ui]

I always thought it was due to the charging circuit not being very efficient at lower rpms hence voltage fluctuates causing the pulsing?

[@vnovoi]

@@steven-vn9ui thank you! This sheds light over something that is unknown to me. I’ll look into “weak charging systems” and how that can be addressed… if any.
