Is verdigris on cables dangerous?

I've already replaced the spark plug and the resistor/spark plug holder on my motorcycle because the spark plug was broken and the holder was covered in verdigris. Now there's also verdigris (on the copper) on the cable that goes to the spark plug. Is it really necessary to replace the cable as well? It would be very inconvenient…

how should greenspan arise on a motorcycle? Greenspan is a copper salt. This results when copper comes into contact with vinegar. But how should vinegar come to the spark plug? Another salt is the compounds with carbonic acid (this salt also produces a greenish coloration, for example on roofs).

The spark plug will probably be more copper oxide. Just carefully remove it with a cloth. Since the spark plug requires high voltage for generating a spark, and has an electrode spacing in the millimeter range, such a thin oxide layer is not an obstacle for the high voltage.

It can happen, of course, that the candle plug is so dirty that sparks already skip in the plug and so no longer arrive at the candle. Scratch parts of the plug (if you clean it with a wire brush) also contribute to the fact that the high voltage is “guided” in other ways.

Greenspan is poisonous, by the way! So get away with vinegar when you have copper pots.

if the cable is long enough, simply nen cm or so unwind, then screw the candle plug nicely deep.

if you turn the candle plug in and out several times, you will have largely eliminated the greenspan.

Apart from the fact that the green pan reduces the conductivity (as well as any other oxide layer on cables and plugs), it is still toxic. But you’ll hardly touch your coffee with the cable. ;

Retire cable when it is still long enough and then sprinkle with solder tins. Or put in a new cable.

‘Greenspan’ is copper oxide and if the line is oxidized, this reduces the conductivity. An exchange is useful!

But no one can force you.

Greenspan is a copper salt with acetic acid. Copper oxide, on the other hand, only one compound with oxygen.

It doesn’t matter how you call the copper roofs are also green. Og meant the high-voltage cable and this has a copper core in older models and can be green at the ends

‘Greenspan’ is not the same as greenspan, there are veritable greenspan and real greenspan.

Here we have transversal greenspan = copper oxide. That’s why it’s set.

See:

The green coloration of copper components is exclusively non-water-soluble oxidation products of copper…

It is therefore not a ‘greenspan’, although this is wrongly referred to by language.

I didn’t want to write a scientific paper here in my answer.

The conductive part of your cable becomes smaller. However, since high voltage is still present, it is sufficient. See how far you’re coming. Definitely clean it up and put a drop of oil on it.

greenspan is just not good for the conductivity, otherwise he does nix

Cables must change because green chip can reduce the conductivity.
