Looking for help concerning a BMK problem. I found a no comm error on my Magnum remote a while back, I romved the panel cover and found no indicator light on the module and voltage to the power terminals 58 V. seemed simple enough, power no light must be the module. Received the module and shunt, installed the module, same thing removed the blue and orange wires from the module, the green LED came on and the remote lost its no comm error, huh what could go wrong with the shunt? I replaced the shunt same thing. Power to the module and no LED unless I remove the blue and orange wires to the shunt, any ideas? Thanks Stillchillin

Typically, they are installed on the negative wire to the battery bus (only cable connection from battery to one heavy bus connection). All other devices are attached to the other heavy shunt connection (that way, the shunt measures all the current into and out of the battery negative bus).
The other two small wire connections are volt meter connections (to the battery monitor). They measure from 0.000 to ~0.050 or 0.250 volts (zero to full scale current). The "cutout" is how they adjust the resistance (if too low of resistance, they cut out a bit more material).
