ammeter

Step 13:  Install ammeter.  I decided to monitor battery current and motor current.  I used romex wire because it has the potential to be at high voltage.  Plus I had some laying around.

The meters fit where the old heater controls were. 

Through the firewall.

The shunt for the motor current hangs off the motor terminal.  A cable will go from the other end of the shunt, under the car, into the trunk to the motor controller.

The shunt for the battery current hangs off the battery stack contactor.

5mm x 20mm fuses inline.
