kailangan mo pa ampere-draw test ang car mo kung may excessive draw, some electricians know how to the that
Hehehe, naalala ko yung mekaniko dito sa talyer na malapit sa amin. Kasi, malakas ang static ng kotse ko noon, talagang parang kuryente na nakaka-shock. So I asked him to do an ampere-draw test. He just gave me a "what-the-hell are you talking about" look, sabay sabi na wala daw silang equipment to do that.

Anyway, to the OP: something is grounded. Try mo pa-check sa reputable auto electrical shops like Rey's or Wizzards
