What is the 60W MagSafe output voltage?
What is the 60W MagSafe output voltage when it is disconnected from the computer?
pamgb1963, the inner large pins are V+ (14.5 / 16.5 / 18.5 / 20 V DC). Measuring with no load will give 6.86 V DC for MagSafe and about 3 V DC for MagSafe 2; the full voltage is provided after a ~40kOhm load is applied for one second
While not easy to see you'll find the side that is opposite the plug pins (where you grab it) in light gray print the specs of the unit. It should be marked 18.5 Volts.

Given the pin sizes I don't recommend trying to use a meter probe as you are more likely going to short it out. I have a spare DC In-board which I wired up with test leads when I need to check a power adapter.
