All the Ammeter does is show current flow into or out of the battery. If you went straight from the battery to a hot junction block and powered the accesories like that what would happen is the alt will have to show all the current going into the battery plus all the current to the junction block because the alt output would have to go thru the ammeter and to get back to the jubction block and feed the accesories. So the ammeter will show more then just the current going into the battery it will also show the current feeding the accesories. Now as long as you hook the hot feed to the accesories that you plan on and take the hot feed from the alt side of the ammeter the ammmeter will now only show the current going into the battery like is should. Thats because the alt will put out the current to feed all the circuits but that current wont go thru the ammeter. Now the voltage reg will still read when the battery volts gets to low and will make the alt put out enough to feed all the circuits and keep the battery volts up where it belongs and the ammeter will only show the current going into the battery. The ammeter does not tell you how much the alt is putting out it just shows how much current is going into the battery to keep the volts at the correct level. So by hooking the hot feed to the relays after the ammeter that means with the car running all the alt output to feed the relays will go from the alt output wire and to the relays and not go thru the ammeter. Only what the battery needs to keep a charge will go thru the ammmeter. Course if you turn on any of it without the car running then it will go thru the ammeter to the relays. Ron
