The letters indicate the function of the switch, as described as following: Letter Switch Identification on the Delco Series Parallel Switch Wiring Diagram Every switch found in the Delco Series Parallel Switch Wiring Diagram is identified with a switch number, which is followed by a series of letters. The basic components of the Delco Series Parallel Switch Wiring Diagram include: The components of a wiring diagram help to organize any project and make the entire process easier to understand. Understanding the Necessary Elements of the Delco Series Parallel Switch Wiring Diagram The Delco Series Parallel Switch Wiring Diagram is composed of several primary elements. This article will explain the components of the Delco Series Parallel Switch Wiring Diagram, as well as provide instructions for reading and utilizing it effectively in any project. With a multitude of uses in automotive, electrical and industrial applications, understanding the nuances of the not-so-simple wiring diagram is a necessity. For any busy professional or do-it-yourselfer, knowing how to properly wire these switches can save you time and effort.

Always use caution when modifying a system. *This is a basic wiring guide and will not cover every application or scenario. Make sure all connections, including battery ground cable, are clean and tight. Alternator ground connection is the casing, grounding back through bracketing and eventually through battery ground cable. The #1 regulator connection must be off with ignition off to prevent battery drain. The main points to remember are both the #1 and #2 regulator connections are BAT+ with key on. This connection is not necessary for unit to function even if it is present. This is one of the three phase connections and is most commonly used to function electronic tachometers. The third spade connection in this diagram is optional and will not be present on all units. For this diagram we are wiring it right back with the alternators output post which is BAT+ full time. The #2 spade on the alternators regulator connection may be either powered full time, or may be wired to be on/off with ignition - either will work. *For repair harness including diode see part number 9840-4033* Depending on switch circuitry there may also be a diode before the #1 spade to prevent the current when charging from back feeding the ignition switch and not allowing unit shut down. This connection acts as a ground allowing the no charge indicator light to work, until the alternator starts charging - the alternator will then push 12v+ back up towards the indicator light cancelling out the circuit and shutting the light off. With key on power is then transferred through the no charge indicator light to the #1 spade on the alternator regulator connection. The ignition switch is most commonly powered from the starter battery stud, but source may vary depending on application. *This diagram shows the simple wiring diagram for negative ground Delco SI series alternators.* If you are looking for the no charge indicator light on the dash to function as well, this should help determine which connection to use. While this series of unit often runs as a self exciting one wire, agricultural applications also used 3 wire connections to the alternator. We are commonly asked how to wire the Delco SI series alternators upon maintenance or upgrading from an older generator.
