I would like to install a small digital Amp meter like this one on ebay
There are various types; 10 amps, 50 amps and higher. Also some of them include a Shunt.
My electrical system is made up of 5 x 110 amp batteries charged by a Rutland 913 windcharger and an engine driven alternator (60 or 80 amps I think); never had any problems. At present there is an old amp meter which I am not sure whether it works or not.
So, which Digital meter do I need; do I also need to have a Shunt?
