What if your 2003 Mercedes c240 has a running voltage of 16 volts is this to high poss alternator?

A voltage output of anywhere between 13 volts and 16 volts is considered acceptable.
If you're still concerned, take your vehicle to any of the major chain auto parts stores [for example, Autozone, Advance Auto Parts, or O'Reilly] to have your vehicle electrical and charging system checked for FREE.
They normally have handheld testing devices which they can attach to your electrical system while in their parking lot, and with those devices can do static and dynamic tests while you watch.

How do you know when you have a bad alternator?
it will not produce voltage or high enough voltage when running should be around 14 volts running

What is the voltage of an automotive alternator?
between 13.5 and 14.5 volts with engine running at idle
How do you know if the alternator is not charging?
Check the voltage at the battery with the engine running. It should read from 13.5 volts to 16 volts. If it reads lower than 13.5 volts the alternator is defective.
What should the voltage output be on an alternator in a 350 Chevy?
13.9 to 14.3 volts with engine running.
Why is the car battery charging at 14 volts running and 13.5 not running?
your alternator charges the battery while the car is running. The alternator actually puts out a higher voltage than 14 volts while it is running, but it is reduced by a voltage regulator (most of which are already built into the alternator housing), to prevent damage and premature death of the vehicles battery. While your car is not running, the alternator is not charging the battery, and the 13.5 volt reading you get is just the measurement of the voltage the battery is holding at that given point.

Why would a 12 volt car battery give off 22 volts?
it won't. The most you will see from a stationary battery with the engine not running is 12.6 volts. If you are seeing 22 volts with the engine running then the voltage regulator is defective and it will ruin the battery. Most modern alternators have the voltage regulator built into the alternator. Replace the alternator.
What is the amount of voltage for a Mercury Sable alternator?

How do you check Subaru alternator?
The easiest way to check any alternator in a car is to have the vehicle running and use a VOLT meter to read across that battery terminals. The voltage should be in the range of 13.4 volts to 14.5 volts..no lower, no higher. If either low voltage or high voltage exist, that alternator is probably defective.
