Conduct a binary search by breaking down the blast into manageable sections to locate high leakage.
The Binary Search is conducted as follows:
Assume Row 5 has an exposed wire in surface harness in water causing a high leakage reading on the Tagger.
1. Divide the blast in half and cut the surface harness at mid-point.
2. Connect the Tagger and check back half for leakage. Should the Tagger display high leakage it indicates a
fault present.
3. Connect Tagger and check front half for leakage. Should the Tagger display satisfactory leakage it
indicates no fault present.
4. Divide the front half and test backward and forward from the centre to narrow down the search area.
5. By repeating this process, the fault is narrowed down to a small and manageable area.
6. Conduct a visual inspection of the surface harness to locate the fault.
7. Fix the problem ensuring all wires are correctly sealed with insulation tape to prevent further leakage
problems.
8. Test the surface harness to ensure all faults have been fixed
