, it fried wires under my dash and my main power feed wire to the ammeter.
Could be the ammeter itself. Not unheard of.
Could that be tested with a multimeter? Its basically a free flowing channel of electricity isn't it?
As others have stated, you need to put your ohmmeter on the battery leads (no battery!!!) and start disconnecting things until the reading significantly increases (higher ohms is a more OPEN circuit.)
The alternator power wire— the heavy wire on the stud, is the first thing I would disconnect.
