INVERTER VOLTAGE DROP TEST
1. Using the Auto Meter BCT-200J tester: Turn the tester on, press “Y” for menu.
2. Select “V Drop Menu” and press “ENTER”.
3. Select “Generic V Drop” and press “ENTER”.
4. Enter in the rated current to test at (USE 120 Amps to test the inverter harness) and press “ENTER”.
5. Connect the large alligator clips to the inverter input posts (red to positive and black to negative) and press
“ENTER”.
6. Connect the small alligator clips to the battery pack (red to positive and black to negative) and press “ENTER”.
7. The tester will show the results for the voltage drop on the positive cable and the results for the voltage
drop on the negative cable.
8. The positive and negative results must be added together to get the total voltage drop for the complete
circuit.
9. The total voltage drop for the complete circuit must be less than “.396” to be within spec.
