Boy can auto electrics drive you around the twist, probably because so much is burried in the chasis and you have only access to small parts at a time. That and that bulbs, especially the halogen type act as shorts when cold, and that the designers somtimes rely on that, as shown in this vid, can confuse many as all you see with a test meter is lots of wires with earths on them. In auto work a test lamp was often your best friend, however times are a-changing and LED lamps show up totally different to test gear. You think your finally good with all this then someone puts a Telsa in front of you.....

Is your garage near an intersection with a traffic light, or do you have an operating traffic light in your garage as decor? I see the reflection of its color cycle in what looks like the air cleaner cover of the engine when you're in the driver's seat, and I thought that would be pretty neat if you had some in your garage just for ambiance.

Some of this crazy wiring is because if you turn on the hazards both panels flash along with the exterior lamps. Also most older American cars used the same tail lamp bulb for brake lamps as the flashers, they had to come up with ways to isolate the circuits. Nobody wants the panel lamps to come on when you step on the brake. Many manufacturers came up with goofy ways of making it all work.

Yep, MANY modern vehicles have the "flasher" built right into the BCM, and then the "click" of the now silent, solid-state flasher is a canned audio file that is then routed through the stereo amplifier and finally through the speaker system. Sometimes through a seperate speaker in the dash, or many times just the drivers door speaker. SO unnecessary in my opinion. Just GIVE us the usual flasher can.

Nice job! I'd get a touch more creative with your indicator lights and current sensor. Use a comparator and potentiometer to set a minimum current to blink the indicators. This way, if one of the bulbs burn out. The indicator doesn't flash and now you'll know there's a bulb out.

When I was a kid in the late 70's we had an old 50's Olds that we used as a run around the back roads / fishing car. It was considered a junker back then, but it ran good enough to get us around the countryside and into pastures. Turn signals never worked on it, we wired them together and just toggled the stalk if we needed to make them flash. This was in the middle of farm country so there wasn't much use for the signals, but even back then they didn't work right. LOL Man, what I wouldn't give to have that old car today. Great video, thank you!!

Sweet ride, Mr. Carlson..!! This was a fascinating introduction to the complexity of even simple electrical systems in vintage cars. I have to say though - If I can see that something is flashing at the back of your car, regardless how unbalanced the timing is, the fact that you did bother to signal a turn or lane change is all you need to stay in my good books.....

Thinking like an engineer, what looks at first glance like needless complexity suddenly appears as elegant simplicity when you include the hazard switch in the circuit. One push-pull switch and a latching center-off SPDT to satisfy that truth table, plus the auto-cancel mechanism in the steering column - whoever came up with it deserved every penny they earned from those patents.

Paul you have a killer lab.I like your SS replacement for the tung sol flasher. Very interesting, but have you considered polarity protection? For instance if a later battery in the auto is replaced and the owner accidentally instantly reverses polarity. I would hate to see your device smoke.
@pdlcourt20 сағат бұрын
Ingenious solution. However my concern is that different humidity conditions in the car (e.g. when driving in cold and rainy weather) may severely affect the timing of the flasher, because of the relatively high resistance values in the circuit. I made a simple timing circuit for outdoor use once and it stopped working completely because of humid weather.

Built like a tank! I'd expect nothing less. I really like how you retained the original clicking sound. I have a cheap $3 Chinese made solid state 6-24v 50 watt max universal relay on my old 6v motorcycle, after testing several different cheap ones years ago I found a brand that worked from about 4.5v or higher so were pretty reliable on an 6v motorcycle with crappy electrics and battery. I bought 5 of them in total as I expected them to last about as long as the tank of gas but to give it credit it is still going strong after 9 years and the remaining 4 are still in a box somewhere.. but I think this winter I'll be building something like this as I do miss the original clicking sound.
@djeffarndtКүн бұрын
Mr. C. Now that the turn signal relay does not depend on the resistance of the turn signal bulbs, will you replace the car's filament bulbs with LED versions as they burn out? I understand that sometimes you may need to add a parallel resistor to the LED bulb so it draws a bit more current.
@MrCarlsonsLab14 сағат бұрын
The current sensor circuit looks for about 30 Ohms, if its not there, the panel lamps will not flash. I designed it this way, so if a lamp upgrade was to ever happen, even a small load such as LED lamps would trigger the panel lamps, and the system would act as normal.
