Re: Altinator output
No. Not directly. Typical DMMs measure current in milliamps; usually 500 or so, which is half an amp. You would need to put a very high capacity low value resistor (200 Watt, .5 Ohm for example) from the output lug to the battery (a shunt), measure the voltage across the shunt, and apply Ohm's law to calculate the current flow.
This is how the remote shunt ammeters work.
