Power Relay Used for Isolation on VR6 Voltage Regulators {4467, 4493}
- Engine:
- 3306B (S/N: B8D1-UP)
- 3406C (S/N: KPS1-UP)
- 3408C (S/N: TAM1-UP)
- 3456 (S/N: C3G1-UP)
- G3306 (S/N: CNR1-UP)
When using a 7C-2700 Manual Voltage Control Group with a VR6 Voltage Regulator, a 138-3809 Power Relay must be used for isolation. Also, when replacing a VR3 voltage regulator with a VR6 voltage regulator and a 7C-2700 Manual Voltage Control Group is being used, a 138-3809 Power Relay must be used for isolation. Refer to Illustration 1 for wiring instructions.
