Measurement:
Test 1: Measure the resistance between the pump terminals as per the table below:
Resistances should conform to the table above.
Test 2: Measure the resistance between each of the pumps terminals and earth.
Expect open circuit for each test.
| Terminals | Resistance (Ohms) | 1 - 4 | 110 |
| 1 - 6 | 215 |
| 2 - 3 | 0 |
| 2 - 5 | 230 |
| 3 - 5 | 230 |
| 4 - 6 | 110 |
Resistances should conform to the table above.
