I bought my 332c 4 months ago cause all the reports were great now you are all freaking me out. I haven't learned to use the thing yet but so far no problems. My iFinder Pro crapped out, now reading thes posts???? I seen somewhere someone said about a voltage problem (high up to 16 volts) I watched my amp meter today and mine briefly went to 16 volts, I'm going to isolate my unit by it's self but what is the remedy to stop that high charge from the engine? Help me out here please and THANK YOU, Ferdi aka Fred
