don't slap me with a search noob. this is very hard to search for ,thanks anyway.

I have a voltmeter on my dash, lately it drops from 14 volts down to 12 volts for 2 seconds when I turn on items like heater fan and stuff. then jumps back up to 14 volts again?

What should i be looking for? malfunction of Alternator, Or bad grounds??

Well the alternator needs to catch up. How old is the battery? Look at your terminals too.
