I called Fluke. The setting I used was supposed to give me straight DC current. So...mystery NOT solved. Where's that damned Larry when you need him??? Unfortunately Larry has been MIA for a while now. You could try him he larryw4csc -at- gmail -dot- com Wilbur is correct that the alternator puts out pulsed DC but the Fluke should average that out to the correct value. The load of the battery also acts as a giant capacitor to further smooth the output. I think at this point you'll need to try temporarily replacing your other ammeter with a high quality shunt type unit and see what you get. As I understand it the output of your alternator goes directly to one side of your ammeter, and from the other side, directly to the battery? Yes, but from the other side of the ammeter directly to the battery _switch_. So the Fluke was around the wire heading to the ammeter. Stephen |
