Induction ammeter relies on induction forces beetween a rotating coil and a magnetic field created by magnets to show the measured value by moving a hand over a graduated scale. I suppose that by "regular" somebody would say the eletronic stuff sold in most shop, with digital display. As a matter of fact, in this last brand, no electromagnetic effec is needed. But what you describe (the coil around the wire in which you want to measure the current), is just a peripheral on the input of the ammeter. It is worth only for AC current : You can't measure DC currents this way. So, on a bike like a nighthawk, no real use except measure the AC current in one of the three phase windings of the stator (yellow wires on the connector at the left side).

Regular ammeter is inline with the flow and measures directly. I'm not an electrician but I believe this is accurate; any electricians out there, correct if I err...   Stanley --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
