2 wire DC ammeters

2 wire DC ammeters

2 wire DC ammeters do not exist, Going about trying to repair this DC 5V-99V 0.1-9.9A Volt and Ampere Meter Detector for Smart Charger and all I can find are three wire Dc Ammeters as I have always known them to be, so I cannot find this Two wire ammeter anywhere online.

Although I have a suspicion as there are a few salesmen who still write the heading “3 wire ammeter” which makes me suspect there must have been 2 wire Ammeters in the past for him to say 3 in his title.

Well, whoever starts selling these Two wire Ampere Meters online or AliExpress is going to make a killing.
