Where is the starter relay located in the Buick Excelle?

[RyleeAnn]

The starter relay of the Buick Excelle model is located in the engine compartment fuse box, at the connection point between the engine and the transmission. Introduction to relays: A relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) reaches the specified requirements. Function of relays: Relays establish an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). They are commonly used in automated control circuits, essentially acting as an "automatic switch" that uses a small current to control the operation of a larger current. Therefore, relays play roles in automatic regulation, safety protection, and circuit switching within electrical circuits.
