Cutlass V6-262 4.3L DSL VIN V FI (1983)
Glow Plug System: Description and Operation
1982-83
Eight glow plugs are used to pre-heat the pre-chamber to aid in starting.
The type 1 glow plugs are 12 volt heaters and are activated when the ignition switch is turned to the ``Run'' position.
The type 1 system uses steady current applied to 12 volt glow plugs.
The type 2 glow plug system uses 6 volt glow plugs with a controlled pulsating current applied to them for starting. The type 2 glow plug system
uses an electromechanical controller to control glow plug temperature, pre-glow time, wait/start lights and after glow time.
The Electronic Glow Plug Control System used on intermediate models uses an electronic module and a control sensor to control glow plug
temperature, the glow plug relay and the wait light. On this system a coolant temperature switch controls the fast idle solenoid through a fast idle
relay.
NOTE: 6 volt and 12 volt glow plugs are not interchangeable and can be identified by the wire connector spade.
-
6 volt glow plugs have a 5/16 in. wire connector spade.
-
12 volt glow plugs have a 1/4 in. wire connector spade.
The glow plugs remain activated for a short time after starting then are automatically turned ``Off.''
Two 12 volt batteries connected in parallel are required for the higher electrical load due to the glow plugs and starter motor.
The diesel starter motor is larger than the gasoline engine starter and is designed to crank the engine at least the 100 RPM required for starting.
An alternator supplies charging current to both batteries at the same time and there are no switches or relays in the charging circuit.
