agreed... without the clamp meter/ammeter tho even a voltage reading of 14.xx doesn't say for sure if the charging is fine.... do toyota shops even carry clamp meters tho?

OP: have you done any mods to the car... anything in which you may have disrupted some wires (such as HID's, stereo, or anything under the dash)?
