yep, adding grounding kit is the shortcut method hehe.

eto ang tama, replace the stock grounding with thicker and shorter wires. matrabaho nga lang. baka kasi corroded na ang mga wires so di na maganda ang connection

here's a link telling you what to buy and how to DIY your own grounding kit. should cost you less than P200. kung wala ka mabili na heatshrink tubes, try mo electrical tape (what i did for my other grounding kit, overpriced yung P1k na gastos ko dati sa ready made na kit). note lang, i soldered the end of the wires sa eye terminals.
