Difficult to start? adjustments? Do not go? Here, replacing the battery no longer helps – the localization of the problem is correct, but you need to look for the causes in addition to the “battery”. Such anamnesis strongly indicates that the spark has either completely disappeared, or is preparing to do so. Therefore, the poles, the ground on the battery, the ignition coil, candles and high-voltage wires fall under suspicion. So let’s go on a trip strictly according to the list.
Everything is simple with the first point: the terminals must fit snugly against the chips on the battery, be clean and preferably treated with special compounds that prevent the formation of oxidation. They have no expiration date, no reason to fail. The second “patient” – the mass – is similar: the point of attachment to the body should not be rusty and dirty, otherwise even a powerful battery will not cope with the rotation of the crankshaft. Therefore, find, clean, cover with protective compounds.
The next step is candles. They need to be replaced periodically, but only when they wear out. Checking is just as easy: unscrew it, throw it on the engine, look with your eyes for a spark. By the way, about her, dear: if there is a spark, but weak, barely noticeable, then we are approaching our main problem. The problem has been found, it has yet to be solved.
There are usually two reasons: the ignition coil and high voltage wires. The coil is long-playable, but still a consumable item. And choosing something new, you need to understand: only the original can be better than the original. However, it is difficult to pinpoint a constructive death on your own – just by checking. So do not throw away the packaging and work with gloves: if the problem is not in the coil, it may be perfectly legal to return it.
Most often, the problem of the absence or weak spark lies in high voltage wires. They wear out, break, crack, begin to pierce. And the quality of the goods on the shelves, to be honest, rarely causes approval. You can, of course, buy the original, but the price is biting: sometimes a five-digit figure is asked for a spare part that is now scarce. Diagnosing a malfunction does not require special tools and skills: just open the hood in the evening and start the car – sometimes the effect reaches the scale of New Year’s fireworks.
So it still needs to be replaced. But there is a moment – and you want, and it stings. Then a folk recipe comes to the rescue: you need to remove the terminals from the existing part, it is not difficult, and replace the wire itself with a new one. Anything with a resistance of up to 3-9 kOhm will do. The best option is the copper cable PMVC 1.5, which costs about 200 rubles per meter and is sold at any hardware store. Practice shows that for a standard replacement of high-voltage wires on four cylinders, two meters or 400 rubles are more than enough.
And then – a matter of technology: we clean the old terminals, solder a new wire to them, generously and not sparing the solder, and check. Voila: the problem was solved with little bloodshed, with our own hands and in a short time.
