car battery

on troubleshooting

• it's indication of failure is not like that of the flashlight battery that it slowly dims.
• volt meter should read 13.2 +/- when car is off or 14.0 when engine is running. if it does not, either replace it or wait for it to fail totally while your parked or driving.
• don't think that if it's new it will not fail. battery life can go from 1second up to 9years. have it checked.

on replacing

• disconnecting: negative first. connecting: negative last.
• don't try to charge a dead battery with the alternator. it requires battery to work properly.
• mind all the parts that uses electricity(alarm, ecu, audio equipments, etc)

gurney flaps

note to self: those are called gurney flaps and not ducktails as it is colloquially called in the philippines. what does it do - you ask? well, nothing much. it just enhances the wing for further downforce. check wikipedia on http://en.wikipedia.org/wiki/Gurney_flap for further info.

but will it work on the rear end if it's not attached to an airfoil? hmmm. i wonder.
