BELT-SERPENTINE 2390238 - Caterpillar

Parts Required
The following chart is for ordering the total parts required for one basic engine installation. Refer to the individual installation topics for the specific parts (and quantity) required. Items and quantity will vary according to the installation options chosen. Customer (OEM) wiring and optional features are recommended. Elimination of any components shown in this installation guide will disable certain engine features. Contact Caterpillar, Inc. when considering component removal. No additional connections are allowed as detailed and described in this publication without Caterpillar Inc. approval. Avoid splicing or soldering wire connections. All wire connections mentioned and illustrated in this guide should be terminated at terminal strips. This practice will ensure engine and system reliability.Service Tools And Publications Required
The engine installation requires the use of an Electronic Service Tool. The Electronic Service Tool must be equipped with the proper software for each and the applicable user manuals. Referring to, and use of the Troubleshooting and Schematic (from Service Manual) is recommended to aid OEM customer installation of electronic components and systems. Installing OEM Components, Sensors and Connections
Power Supply Connections to Start (Ignition) Switch(es) and Starting Motor
Recommended Wire from Battery to Starting Motor
The wire size (AWG) to -Battery Bus Bar to which components are grounded MUST be of adequate size to handle maximum current for the circuit.
All negative battery connections MUST have a common ground that terminates at the -Battery Bus Bar. Refer to Battery Circuit Requirements And Considerations in this guide for additional information.
Proper grounding for vessel and engine electrical systems is necessary for engine/vessel performance and reliability.
Improper grounding will cause uncontrolled and unreliable circuit paths. This can result in damage to the engine crankshaft main bearings, crankshaft journal surfaces or other engine components. This may also cause electrical activity which may degrade vessel electronics and communication equipment.
The alternator, starting motor, and all electrical systems MUST be grounded to -Battery. The alternator and starting motor must also meet marine isolation requirements.For engines which have an alternator grounded to an engine component, a ground strap MUST connect that component to -Battery and the component MUST be electrically isolated from the engine.Grounding (-Battery Bus Bar Connections)
The problems with intermittent power connections are often very difficult to diagnose and repair.A bus bar with a direct path to -Battery is permissible and recommended to use for all common ground connections. Refer to Battery Circuit Requirements And Considerations in this guide for additional information.3406E Remote Ignition Switch With Engine Mounted Control Panel
Figure 1.22 - 3406E With Control Panel Connections. All wire to be 14 AWG unless otherwise specified.1. Connect from +Battery Bus Bar with appropriate circuit protection, to the Customer Ignition Switch (CIS) positive terminal.2. Connect from the Customer Ignition Switch (CIS) ON terminal (Run), to J3 pin-30 (Remote Run).3. Connect from the Customer Ignition Switch (CIS) S terminal (Start) to J3 pin-29 (Remote Start). A customer provided Shutdown Switch should be installed at each operator station to shut down the engine without removing power to the ECM. Refer to Remote Shutdown Switch
