| 5 | | ''This test outlines the steps required to discharge the RBAT-2 installed on the VSTB. |
| 6 | | |
| 7 | | = RBAT2 Discharge Test |
| 8 | | |
| 9 | | == Setup |
| 10 | | Equipment Required: |
| 11 | | * ≥ 100W Power Resistor (Approx. 10 Ohms) |
| 12 | | * 44 Socket HD D-sub BOB Cable ST12024-3S for BCB2 P2 (See BOB Cable Configuration) |
| 13 | | * Volt Meter |
| 14 | | * Amp Meter |
| 15 | | * Set of hard wire with banana plugs and clips for resistor |
| 16 | | |
| 17 | | Steps: |
| 18 | | * Demate BCB2_J2 connector from the RPA |
| 19 | | * Install BOB cable at BCB2_P2 (Harness Side of W0104) |
| 20 | | * Install fluke amp meter in series into the battery circuit to measure the current discharging from battery. |
| 21 | | * Attach Hi side wires to RED SiDE of Pins 1, 2, 3 on BOB-1. Other ends of these wires to an empty Pin 1 on BOB-2. |
| 22 | | * Attach Lo Side wires to RED SIDE Pins 12, 13, 14 on BOB-1. Other ends of these wires to an empty Pin 2 on BOB-2. |
| 23 | | |
| 24 | | == Test Steps |
| 25 | | * Measure the voltage across Pin 1 and Pin 12 on RED SIDE of BOB-1 |
| 26 | | {{{ |
| 27 | | Expect ~30.4V |
| 28 | | }}} |
| 29 | | * Install Power Resistor across Pin 1 and Pin 2 of BOB-2. Monitor current draw on amp meter |
| 30 | | * Take Voltage measurements and Current Measurements every 10 seconds |
| 31 | | {{{ |
| 32 | | Voltage should drop at a steady rate |
| 33 | | }}} |
| 34 | | * After 1 min discharging, remove the power resistor from BOB-2. |
| 35 | | * Measure the voltage across Pin 1 and Pin 12 on BOB-1 |
| 36 | | {{{ |
| 37 | | Voltage should drop by <1V |
| 38 | | }}}'' |
