Bench Testing: Rectifier
Using ohmmeter, check for continuity between each diode. See DIODE CONTINUITY table. See Fig 1. If continuity is not as specified, replace rectifier.
DIODE CONTINUITY

| E | PN, P1, P2 & P3 | No |
| B | PN, P1, P2 & P3 | Yes |
| T | PN, P1, P2 & P3 | Yes |
| PN, P1, P2 & P3 | E | Yes |
| PN, P1, P2 & P3 | B | No |
| PN, P2 & P3 | T | No |
| PN | T | Yes |
