Thanks for watching! I hope this little bit of information was informative. Please share this video if you known someone who might find it handy. Be sure to check out my other videos of the ITB EFI conversion to my Datsun 240z. 👍 Cheers!
Thank you! Had to re-learn all this when the 30-year-old coil on my old Jag failed and left us stranded halfway up a steep hill. £26 for a replacement coil and all works beautifully again. Moral: old coils fail, so replace them before they go!
TO KEEP IT SIMPLE... The ignition coil is a high voltage step-up transformer with a primary and secondary winding. For example... The primary may have 150 windings and the secondary 1500 windings. A transformer needs AC or pulsating DC to induce voltage on the secondary winding. When the points are closed the primary winding magnetizes the core and charges the condenser. When the points open, the primary voltage collapses and the condenser discharges back to the coil reversing the current flow and creating momentary pulsating high voltage to the spark plugs. Also... the condenser is wired in parallel to the points to prevent the points from burning up.
I have a 94 Honda accord, a distributor and rotor .... can i put a "more powerful" coil on there with nothing else? Remove the current stock one, and install one similar to the one pictured in your thumbnail? increase spark plug gap slightly . I am not finding many videos on just changing the coil (not coil packs for each plug) most want a control box as well, do you have to have a control box??
+My Looney Bin you should be able to improve spark by changing the coil. Matching coil resistances is important when you do this. Is there a reason you want to investigate a different coil? A control box or igniter is normally required when the ECU or switching system lacks the capability to handle the current needed for a direct control of the coil.
@@kyushaspeed it is my understanding, that if I can get a "bigger" spark, I could potentially gain more "power", more "explosion" ... but I am not sure if I would have to change my fuel injectors to accomplish this purpose. For me it is a learning process for sure, and trying to make the Accord go faster, more quickly ... mostly learning and understanding. I feel like I understand how the engine works, but modifying it to make it work harder is a bit more complicated.
+My Looney Bin a stronger spark normally improves efficiency of combustion by providing opportunity to bur more of the fuel mixture that is otherwise left unburnt. This in theory will increase the peak cylinder pressure on the power stroke and increase power, but unlikely to give crazy big gains. Idle, cruising and starting benefit the most from stronger spark.
@@kyushaspeed thank you, I'm a little old to be getting into this stuff, but, hey, just trying to live and experience as much as possible. Thank you so much for your time, that helps out a lot!

Thanks a lot. I hate not knowing this stuff. Subscribed.
GREAT BEST VIDEO

Thanks. I am looking forward to the dwell episode soon...
+Michael Sliwinski I’m hoping to make dwell the topic of next weeks episode 👍
