True, the cost is not very encouraging. The prices here are also for one. I want to rush to buy. What it is? This is essentially a high-voltage wire, which is put on the candle with one side, and the other side is inserted into the hole of the module / coil, with which this module was previously put on this candle. And a high-voltage sensor is already clinging to this extension cord, which is actually a clothespin of one design or another. The clamp-on sensor in this case will simultaneously show signals for several cylinders, which will make diagnostics impossible. Maybe there are simpler and cheaper solutions? Moreover, the high-voltage wires themselves can be practically any, in fact, only adapters are needed from the wire to the tip of the module / coil. Let’s see the prices. And you also need to buy a set of wires. Is it possible to save money with a 3D printer?
3D printers are quite confidently entering our lives, and often help to replace lathes and milling machines for the manufacture of useful and not so things. And you need at least 4 of them. * THIS IS NOT A REVIEW! THIS IS A DIY COMMUNITY! Thus, the usefulness of such extension cords is beyond doubt. And put it together like this: Up to the complete impossibility of doing something in the case of, for example, an old Saab, where the module is closed with a thick metal case, or old Peugeots / Citroens, where there are two dual coils in the module and through the entire module, from 1 to 4 cylinders and from 2 to 3 pass current-carrying. We will consider one useful and rather expensive thing in this article. But after the appearance of the printer, no one bothers to make an analogue of that branded little white solution, right?
When diagnosing an automotive ignition system, a sensor must be connected to each high-voltage wire or ignition coil. And such adapters exist. Here is a photo of such a module from Peugeot: A few years ago, I solved this problem quite simply and practically for free.
But the toad puts up a fierce resistance! Let’s try to mold high-voltage extension cords from a ram and sticks! In such cases, high-voltage extension cords are used. It looks much more serious than high-voltage wires wound with electrical tape, it is an order of magnitude more convenient to work with, but unfortunately it does not hold perfectly. You will need high-voltage wires and protective shipping caps from lambda probes, in which you need to make a hole slightly smaller than the diameter of the wire And if in the case of individual coils (when the coil is put directly on each candle) there are options in the form of sensors on suction cups and overhead sensors, and often you can find a malfunction simply by “walking” with such one sensor through all the coils, then for ignition modules that combine several coils in one housing and are placed on all the candles at the same time – the task becomes much more complicated.
