Guys...I have a question.I'm sure a lot of u are familiar with voltage stabilizers and grounding cables rite?Ok...so I've put these 2 things into my car(proton satria) and at first it did stablize the voltage hence not much lose on horsepower.After 4-5 months somehow i've experienced the fluctuation of voltage and lose of power again but only this time it's quite a lot.my headlights flicker for a nano second...it wasn't like this b4.so....wat's the problem???is it the voltage stabilizer rosak???pls care to give some advice....thanx!
