Glow Plug Relay
The glow plug relay controls glow plug on-time. The glow plug relay performs 3 functions:
- Pre-Glow - Pre-heating time with ignition switch on.
- After-Glow - Pre-heating time with ignition switch on after glow plug light goes out (after-glow lasts a few seconds).
- Cranking Glow - Pre-heating time with ignition switch on and engine in cranking mode.
