A new YL Electrical solenoid will restore precise, quick starts in a vehicle when it’s time to replace an older one.

How Solenoids Work:

Solenoids work as electromagnetic switches, serving as the link between the ignition and starter. The solenoid engages when the ignition key is turned, creating a link to allow for the flow of electricity to the starter. Once the engine starts, the solenoid disengages, cutting off the flow of electric. Solenoids have wire coils that wrap around a mobile core. As electricity travels through the coil, the core becomes magnetized, which creates force to push the mobile core outward to engage gears on the starter.

Solenoid Troubleshooting Guide

Internally & Externally Switched Solenoids

Push & Pull Type Solenoids

Getting Started Before beginning the actual troubleshooting, complete the following:  

Identify and learn about the type of engine or application on which the solenoid is installed (consult with the customer).  It is important to correctly identify the type of solenoid unit you have. This can help during troubleshooting and when communicating with the factory about a problem.  The label on the solenoid contains a model number descriptor and a part number descriptor. The part number descriptor specifies the type of features the solenoid has.

Part Number Descriptor 

Below is an explanation of a part number descriptor found on a typical solenoid. 

Example: Part Number 12A2U1B1S1A 

Reading from left to right: 

12 Indicates volts: a solenoid can be 12 Vdc or 24 Vdc 

A indicates the mounting style

A = Flanged B = Threaded C = Based 

2 Indicates plunger type 2 = Ext. Thread 1/4-28 3 = Ext. Thread M-6 6 = Int. Thread 1/4-28 7 = Int. Thread M-6 

U Indicates grounding G = Grounded U = Ungrounded 

1 Indicates termination type 1 = Screw 2 = Spade C = Connector L = 3 Wire Leads 

B1 Indicates boot type B1 = Constant Volume B2 = Bellows 

S1 Indicates return spring forces Consult the factory for ratings 

A Indicates special options A = Aux Terminal C = Conduct Cover CC = Coil Commander 

Consult the factory for additional information or explanation.
