Why do most manufacturers use a 3 pin connector with only 2 pins populated ?
Ive come up with an idea to bridge a pin on the charge cable to then turn my shunt gauge on through a micro relay when charge lead is connected its a fairly simple circuit but it requires that the charge lead be a removable link so my shunt powers up when i turn the ride on or put the charge lead in its socket.
My shunt is bidirectional with memory so to save time reseting it when i charge this way i can just leave it calc on discharge and on charge and it should stay close to pack actual contents.
Is this what the 3rd pin was intended for ?
