I have a dual alternator / dual battery setup- my question is can I somehow
just use the single hall effect current sensor I have to determine output of
either/or alternator or do I need to get 2 of them and use a toggle? I was
thinking that possibly I could pass both alternator output wires through the
ring and then it would measure all current passing through regardless of
where it was coming from, but I am not sure if it will work this way, or is
there another solution- maybe put the sensor on the single ground cable that
goes to both batteries?

Hall effect sensors work just fine with multiple wires running through
them. The reported current is the total what is running through all of
the wires. In fact, you can loop the same wire through the sensor to
get higher readings. If you want independent readings, you need
independent sensors. Hooking 2 sensors to the same display, or EIS/EFIS
input with a toggle means they have to be calibrated the same (or at
least close enough Smile
