Although small in stature, solenoids are important devices to ensure an operational aerial lift. As an electrical component of an aerial lift system, solenoids convert electrical energy into mechanical motion. Essentially solenoids turn electricity into movement, which is critical for multiple purposes such as throttle, speed and stop control. Accordingly, during routine inspections and maintenance, operators should be aware of warning signs of bad solenoids. The following highlights some important warning signs and provides an understanding of how to find quality replacement parts that fit a variety of aerial work platforms.
Potential Warning Signs of a Bad Solenoid
From routine wear and tear to diagnostic errors or even environmental factors can result in problems with solenoids. As a result, understanding potential warning signs will help operators keep their aerial lifts running. Although determining the exact cause of a problem may require additional investigation, these signs of a bad solenoid indicate that an immediate replacement part may be needed:
- Clicking: A rapid clicking sound may point to a solenoid problem, often due to a loose connection or wiring issues. Alternatively, a single clicking noise indicates the solenoid is receiving the ignition signal, but has a connection issue.
- No response when turning the key: When you turn the ignition key, there's no sound or engine cranking at all.
- Grinding noises: The starter cranks but the solenoid doesn't properly engage the pinion gear with the flywheel, causing grinding.
- Starter keeps rotating: The starter continues to run even after you've released the key or turned off the ignition.
- Slow or weak cranking: The starter motor turns over slowly or weakly due to poor electrical contact.
- Intermittent operation: Sometimes the engine starts normally, other times it only clicks or doesn't respond at all.
- Burning smell: This can indicate overheating of the solenoid due to bad connections causing resistance and heat buildup.
- Visible damage: You may see a cracked casing, broken mounting bolts, or corroded wiring connectors on the solenoid.
- Battery drain: A stuck solenoid can cause the battery to discharge even when the vehicle is not in use.
- Unusual system readings: If hydraulic pressure readings vary unexpectedly during operation, this inconsistency may be a sign of a bad solenoid.
- Overheating: Power & Motion notes that high voltage exposure or disrupted plunger operation can cause coils to overheat and are some of the most common causes of this solenoid issue.
Dangers of Associated with the Signs of a Bad Solenoid
Scissor lifts, boom lifts, vertical mast lifts and other aerial lifts depend on solenoids for multiple control functions, including platform movement and stabilization, steering and driving. Consequently, regular inspection of solenoids and replacing this component as needed are vital for both safety and continuous use. Ignoring the signs of bad solenoids may result in the following problems or dangers:
- Reduced lift lifespan, which increases lift operation costs over time
- Control failure which may result in increased fall risks, destruction of surrounding structures or materials or personal injury
- Increased potential for tipping or crashes due to unavailable emergency brake or less brake control
