Honda is a well-known brand in the world of automobiles and machinery. The company has been producing high-quality and reliable engines for a long time. One of the most popular engines produced by Honda is the Honda GX390. The GX390 is a four-stroke, single-cylinder engine that is commonly used in generators, pressure washers, and other industrial applications. One of the key features of the GX390 is its electric start system. In this article, we will discuss the wiring diagram for the Honda GX390 electric start system.
What is an Electric Start System?
An electric start system is a type of starting system that uses electricity to start an engine. In traditional engines, a pull-start system is used, in which the user pulls a cord to start the engine. An electric start system makes it easier and more convenient to start an engine because it eliminates the need to use a pull cord.
The Honda GX390 electric start system consists of several components, including the battery, starter motor, solenoid, and wiring. Understanding the wiring diagram is crucial to properly install and maintain the electric start system.
