But why this doesn't happens on myvi & viva? Hopefully perodua will review on it to make sure the battery supplied is good enough for the whole car.
Thanks singk!
u r welcome bro.
strangely my myvi is having this problem as well, it's more obvious when the aircond compressor kicks in. anyway, this myvi girl still running well, it's her 9 years this year. and the battery replacement interval is normal as well (approx 2 years)
well, back to your point, to manufacturer, cost is everything, if you wanna have a circuitary that doesn't dim a while when aircond kicks in, either you change the aircond clutch to a lower power ones (that gives you an even hotter aircond since perodua aircond is not so cold adi), or you bump up the cables size and the power rating (not guarantee to solve the problem but it will reduce the symptom). And this increase the cost a lot.
Imagine you have a main water pipe (main trunk cable) supplying water to all the pipes (electronics stuffs, injectors, sensor, fan, light etc), when you switch on the largest pipe (the aircond), the other pipe will surely feel the drop in pressure the moment the big water pipe opens. The same happens when you switch on dome light and starting engine, the dome light dims. I think perodua will try many ways to save cost so we gotta bear with it (unless we wanna pay more for non dim lights during aircond kicks in)
