Fred=0AYou can measure current by noting the voltage drop across a short le
ngth of=0Awire, very small drop in the case of the main buss but still meas
urable.=0AThen, Amps equals Volts divided by Resistance=0AGraham=0A=0A=0A

..thank you for your thoughtful reply to my concerns, especially by spellin

t I needed, although, when you write:=0A=0A> To measure amps, you need to h
ave a resistor somewhere in the wire. I=0A> prefer to have this directly at
the battery because this resistor is=0A> doing the least harm at that plac

hat I have no idea WHY a resistor is essential, nor can I imagine what crit
eria are appropriate for sizing such a resistor, nor do I understand why fa
ilure would cause minimal harm if it's located directly at the battery...
