What does the warning buzzer sound on a Cadillac Seville?
The KEY WARNING BUZZER sounds whenever the key is in the ignition switch and the left front door opens. The closed IGNITION KEY SWITCH and LEFT FRONT DOOR SWITCH also provide a ground path (through the LT GRN wire) for the “Stop: Engine Temperature” INDICATOR, lighting the bulb as a test.
What was the ignition switch on a 1978 Cadillac Seville?
Figure 6-1 shows inputs which govern the outputs of the Electronic Control Unit. For detailed procedures, read “Electronic Fuel Injection” in 1978 Cadillac Service Manual. With the IGNITION SWITCH in Start or Run, current flows to the DISTRIBUTOR through the PNK wire.
Where does the DC current come from on a Cadillac Seville?
A DC voltage is also applied at the field winding, through the Diode Trio. Field current is provided by the Diode Trio or from the BATTERY through the GENERATOR INDICATOR.At low engine speed, current flows from the BATTERY through the GENERATOR INDICATOR to the FIELD WINDING.
How does the warning light work on a Cadillac Seville?
The GENERATOR WARNING LIGHT RESISTOR draws current and the WARNING LIGHT glows. Current flows through the REGULATOR to the GENERATOR FIELD WINDING. The rotating field and the rectifier diodes produce a DC generator output voltage at the BAT terminal.

Where is the EFI switch on a Cadillac Seville?
– To check LEFT FRONT DOOR SWITCH, connect wire from FUSE BLOCK connector (C101, terminal M) to ground and observe indicator light. The EFI controls fuel injection and limits emissions by balancing the air/fuel mixture. NOTE: The normal engine timing advance is 10° before TDC (8° in California).
