OLD think about an AMP meter as a pressure and direction gauge. The positive and negative are the direct of the current flow. The Amps is a measure of the pressure or rate of the current flow.
So on a simple AMP meter it needs to have all of the current pass through it so it can measure the direction and rate. Generator or Alternator, the battery wire has to go through the AMP meter. The way you have been wiring them is just sending the ignition current through them. So if you just have the unit running, with nothing turned on, the AMP meter would only see the little current the ignition switch/system uses. The wire you have going directly to the battery(solenoid terminal) is carrying all of the major load. That kind of short circuits the APM meter. It jumps the current around it.
AN induction AMP meter works about the same but it just reads the magnetic field around the wire to work. The Ford tractor ones that you just run the wire through the loop or JD 200 series lawn tractors that you clip the wire through the plastic holder on the back of the gauge, work this way. They still need all of the current to flow through them.
