General User Instructions:
Conducting electrical tests:
Before starting, ensure all blanking plugs are fitted to the test box and place on a flat surface. Then connect the EV connectors to the battery connection points.
Voltage Test:
- Remove the voltage test point blanking plugs.
- Noting the correct polarity insert the voltage tester probe tips in to the voltage test points until you feel the tips reach the internal test points.
- Conduct the voltage test using the voltage tester.
- Once the voltage test is complete, remove the probe tips and replace blanking plugs.

Insulation Test:
- Remove the tip cover from the insulation test probe so that it exposes the lantern tip.
- Remove the +Ve insulation Test Point blanking plug.
- Insert the insulation test probe lantern tip into the +Ve Insulation Test Point.
- Conduct the +Ve Insulation Test.
- Once the test is complete, remove the test probe and replace the blanking plug.
- Remove the -Ve Insulation Test Point blanking plug.
- Insert the insulation test probe lantern tip into the +Ve Insulation Test Point.
- Conduct the -Ve Insulation Test.
- Once the test is complete, remove the test probe and replace the blanking plug.
