my alternator is giving too much voltage.

Sounds like the voltage regulator is bad. The majority of the time they are built into the alternator, but you'll have to check to see if you can replace the voltage regulator separately.
Anyways, don't drive it like this as you'll damage the battery.

Measure it with another voltmeter and if you get the same result and your battery and cable connections are good, replace the alternator because the voltage regulator is not working. Maximum voltage should be under 16 volts DC

It's a voltage regulator problem. If the regulator is integral to your particular alternator, you probably need to replace the alternator. If it's a separate component, just replace the regulator.

depend what kind of vehicles you have. some vehicle has an alternator regulator located outside the alternator. if the regulator is bad on this design, the alternator is okay. most new vehicles start putting the regulator inside the alternator. if you have this style, then your alternator is bad. fix this problem quick before you damage the battery.

Depending on the age of your car as to whether it has the rectifier/regulator built in or separate. I would say whichever it is the regulator is faulty.

Is there a bad smell (hydrogen sulphide) around the engine bay?
That's your battery being fried that is.
Better save up for one of those as well.

That's a little to high it should be 15.5 or in that area. your regulator on your alternator is bad.
