Well done! I'm 72 and I've always did all my own work on my cars, motorcycles, trucks, etc. and I still do. As wonderfully reliable today's electronic ignitions are, I almost miss doing tune-ups. I found this video because one of my grandsons, who is a mechanical engineer working on his master's degree and who works for Honda asked me about points, condenser, coil ignitions work. You're description is perfect and very clearly presented. I still have the tools I used for my old ignition systems including a dwell tachometer, timing lights and even the special flexible points adjusting tool that was used with the old Delco distributor caps with the little window to access the points adjustment screw. One big thing that's changed with cars since since electronics took over is how crammed the engine compartment is. The engine compartment on my old '57 Chevy was so big and so empty that my wife (who was my girlfriend at the time) could actually climb in the engine compartment and I could close the hood! (Don't ask me how I know that because I can't remember why we did it.) Also, things were so simple. You opened the hood on a car back then and all you saw was an engine, a generator (before alternators replaced them) a battery and a radiator. there was tons of room to work and things were so simple and uncomplicated. That was even before PVC valves and EGRs were used. My father was born in 1909. His first car was a Model T. He would tell me about how you could re-build the engine in your garage in a few hours. He said that the biggest problem with Model Ts and similar cars back then was having to fix flats all the time. I thought about all the things he must have known that are all but forgotten now except by antique car collectors. Then I am reminded that that's how my grandson's must see me. Thanks again for your fine video.

Thank you so much. Actually repairing a 1956 Ford tractor, and having to replace the points and condenser. Was a little lost on the contact breaker verbage on gap and function. This was perfect and now heading back outside to adjust them properly. Great video, well explained and appreciate the visual hands on. Keep them classics runnin!

Thank you. I'm working on a 1975 Caterham 7 with a Lotus 7 dual overhead cam wngine and I have never had to deal with points before. This was clear and valuable information ... and now I have spark again. Seems my points were so corroded (engine had not run in about 5 years) they were always open and no spark could develop. I used a 2-sided nail board (file) to clean everything up, and then gapped to 20 thou. All good now. Thank you again.

Thank you for the instruction. Currently working on putting a vintage British dirt bike back in service: a 1971 Greeves 380 Griffon Scrambler. It has a Magnito Mechanical Breaker Point Ignition (Stefa, made in Sweden). Took it to the track the other day to test. Started twice, ran for 300 feet and died. Whet plug, no spark. Hence, my refreshing my Breaker Points knowledge. Thanks again for the refresher. BTW, when demonstrating spark, make sure you have a black background for the spark to show. Thanks.

Hi Adam, nice video. My 67 Mustang distributor has a small piece of felt in the distributor shaft, and it's recommended to oil when you do maintenance. It helps to lubricate the bearing for the shaft of the distributor. I couldn't tell if your distributor has any felt in the center of it or not. As you said not all distributors are the same.

Well done Adam good to see knowledge and skills being shared, just a little about the condenser, when the points open and the magnetic field in the primary side of the coil collapses it induces a high voltage in the secondary side as you said but it also generates a back emf of around 500 volts in the primary the purpose of the condenser is to absorb and dissipate it, if it fails that's when you get excessive sparking and burning at the points a telltale sign is a white powdery deposit that creates a bad contact and misfiring, you make me feel old when I was a lad this was state of the art lol.

@@daphnejames3571 It is sometimes good practice to use a protection diode on inductive loads such as across the pos and neg of the coil in this case the points are switching the coils negative so you can't use one in place of the condenser it probably wouldn't handle the voltage spike anyway being a semiconductor it can only go open circuit if it fails best stick with the condenser if you're having problems getting one the right physical size you can put them on the outside of the distributor.

Try taking the HT wire from the centre of the distributor and set it about a quarter inch from the block and there should be a big blue spark as the points open with ignition on. The spark on the points is less to see.

Adam I was testing my points today by opening /closing them using a screwdriver to test if they spark.. The surfaces are good and a new coil fitted. They were only sparking SLIGHTLY and not every time they were opened. I was testing to seeing if the condensor may be faulty (orange spark instead of usual blue colour) Do I suspect the condensor as a result of this ? It would be good if you might make a video of a good condenser in operation against a failed one.... Thank you Ian

I need some help, I have a world war II generator that was running before I restored it and painted it. I made sure all my ground points are grounded down to pure metal getting good ground on my positive areas too. I got it wired correctly I have the wire diagram in the distributor is not getting sparked the spark plug cylinder holes I thought that might be a problem so I sanded it down and made a good ground point for the spark plugs still no spark. It's a 4-cylinder Hercules engine. My coil is good much distributor is good my condenser is good everything is good just no spark I'm missing a wire somewhere. I have one wire negative from my distributor to my coil negative to negative. From the coil positive to positive to the ignition switch. Just curious if you have any thoughts of where wire might be missing

I like the idea of electronic ignition to replace the contact points, but have heard of a lot of these cheap systems failing, so I tend to stick with using points... Question. Would excessive side play in the distributor shaft cause erratic idle, would you think ? Thanks

Yes that would cause running issues since the point gap would constantly be changing as the engine rotates.

Can a coil be damaged, yet not completely burnt out? I ask because I am having a weird problem where my old chevy truck won’t idle (though higher rpms work fine), and somebody suggested it could be a bad coil. Just about all else is new, and there are no air leaks anywhere (brand new carb).

I assume it is to advance or retard the ignition timing never seen that before normally (on german cars) you turn the distrubutor clockwise or anticlockwise to adjust ignition timing in accordance with mfg specification e.g. 6 degrees after TDC.

@@kaspersvendsen8510 yes you're correct it's for fine tuning, in the bad old days when we had 2star and 4star leaded petrol with a different octane rating you could tweak it to suit, advance as much as you could but if it started pinking ( pre-ignition ) you could retard it slightly, now we have 95 octane as standard we don't have to, however some modern cars have knock sensors and do it automatically and these can benefit from 100 octane, if you don't have them then no benefit don't bother save your money.
