I installed one 75mV shunt and have the Victron 50mV shunt in.
Connected one meter to the 75mV shunt. Took the reading.
Connected a second meter to the same shunt. All readings were unchanged. I did pre cut the wires to each meter, and they are not the same length to where they will be permanently installed.
Hooked up a third. All readings unchanged. As the 3rd is for testing only. I put on a 2 pole isolation switch, for a quick disconnect.
Put a load on (fresh water
pump with water
running). Took the reading then Isolated the 3rd meter... All readings unchanged with and without the third.
I only need the 2 meters with the Victron, so the 3rd is back in the spare pile !
For the test, I got power from the engine
bank to power the display.
Thanks for your feedback !!
