Alternator question
Are you saying you are checking for voltage, and are putting one lead of the volt meter on the + battery terminal and the other on the frame of the alternator? Or are you saying you are using the continuity tester between battery + post and case of alternator, you are getting continuity (i.e. it beeps)?
If checking voltage, then yes,... that's what you should be getting (12 volts). The case of the alternator should be grounded, so when you touch the red lead of the meter to battery + post, and the negative lead to the alternator frame, you should see 12+ volts on the meter.
Look at it this way,... your meter actually is measuring voltage difference, so when one lead is connected to power (12 volts) and the other to ground (0 volts) it reads 12 volts (12 volts - 0 volts = 12 volts)
If checking continuity,.... then no, you should not see continuity between the battery + post and the case of the alternator. If you are, then something is shorted. Just to clarify,... on a typical Fluke (or other brand) electronic volt/ohm meter, when you put it on Continuity checker and touch the leads together, it beeps.
In the attached picture of a Fluke meter, the red circle is setting to check DC voltage. The yellow circle is the continuity tester setting.
