Our aftermarket solenoids are manufactured to exacting OEM specifications for perfect fit and superior performance. We make sure only premium materials and uncompromising craftsmanship go into every electrical unit. 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

Preliminary Check 

The purpose of this check is to do a quick visual scan of the setup and look for some obvious damage or problem. Frequently, such an inspection can save a technician valuable time and effort.  1. Check for broken parts. Inspect the rubber boot. A torn boot can allow dirt to enter and increase the drag or friction on the plunger. 

2. Check for blown fuse, broken wires or loose connections. Check for burned out solenoid coil—usually evident by pungent odor. 

3. Check the solenoid mounting. Look for loose mounting screws that can cause misalignment, resulting in reduced solenoid force. 

4. Check the location. Although the solenoid is designed to operate in harsh environments, locations with excessive heat buildup, constant exposure to liquid and particulate contaminants can affect the solenoid operation.  

Power to the Solenoid 

1. Disconnect the solenoid from the linkage and the control lever. Apply power and see if the solenoid pulls in. If the solenoid pulls in, it is getting power to operate. 

2. If the solenoid does not pull in, check voltage at the connector and confirm at least 10 Vdc is being delivered to a 12 Vdc system and 20 Vdc to a 24 Vdc system. This is the minimum acceptable voltage. 

3. If the voltage reading is not acceptable, check the wiring harness and make sure battery voltage at the battery posts is within manufacturer’s specifications. Replace battery if needed. 

4. If the voltage readings are acceptable, but the solenoid does not pull in, prepare to remove the solenoid from the application and test it on the bench.
