I will also check my shunt connections along the negative power wire.
If there was a connection problem on the actual power wire, the system would not be operating correctly, and you'd have trouble with the motor spinning or driving the bike correctly.
If that is not happening, there wouldn't be a problem with the connection.
If it is happening, then you should also be telling us about those symptoms (and any others besides the suspected-incorrect readings in the CA).
Its an external shunt with the JST wired to it for the CA.
Im assuming the shunt has to facing a certain way when the JST wires are hooked up to it?? One end towrds controller and the other to the battery
The shunt itself isn't directional. but the thin (blue/white) wires from it to the CA do have an order. However, if you did not change this order when connecting the new controller, and did not unbolt the shunt completely (leaving the battery end connected to the battery cabling), then it cannot have changed so current direction will still be correct and so would the readings.
If you disconnected the shunt then you must make sure you reconnect it to the system the same way it was when it was working.
Fyi..CA is reading 54kw standing still and only bike is powered on
That usually means you need to "zero" the shunt current reading in the CA; it's in the advanced or shunt menus someplace. This tells the CA what the zero current reading should be.
If this problem keeps happening it means there is a connection problem between the CA and the shunt on those thin wires, so the voltage it reads between them is incorrect, so it displays the wrong current.
