Westwood Solenoids

Westwood Solenoids
Westwood starter solenoids function as electromagnetic switches engaging starter motors to crank engines on electric-start equipment. Our solenoid inventory includes Westwood solenoid switches, mower solenoids, replacement solenoids, and starter relay solenoids for TimeCutter, Z Master, and walk-behind models. Westwood Spares stocks Westwood starter solenoid assemblies in stock with correct mounting configurations and terminal arrangements for all major model series, with worldwide shipping on all solenoid orders. These essential starter relay components use low-amperage signals from ignition switches to control high-amperage circuits powering starter motors, eliminating need for heavy-gauge wiring throughout operator controls.
How to Identify your Westwood tractor

Frequently Asked Questions

Why does my new Westwood solenoid still click?
New solenoids continuing to click indicate problems elsewhere: weak battery unable to power starter, poor ground connections, corroded battery cables, or seized starter motor. Verify battery delivers 12V to solenoid under load.
Why does my Westwood solenoid click but not start?
Solenoid clicking without starter engagement indicates insufficient battery power, corroded solenoid contacts internally, loose cable connections, or failed starter motor. Jump solenoid terminals directly; if starter spins, solenoid needs replacement.
How do I test a Westwood starter solenoid?
Test solenoids by checking for 12V at both large terminals when key is turned to start position; should have battery voltage on one side always and voltage appearing on other side when starting. No voltage on starter side indicates failed solenoid contacts.
Can I repair a clicking Westwood solenoid?
Solenoids aren't repairable as internal contacts wear creating high resistance; replacement is required. Attempting repairs risks unreliable starting and potential safety issues from intermittent operation.
What causes Westwood solenoid terminals to melt?
Melted solenoid terminals result from loose connections creating excessive resistance and heat, corroded terminals increasing resistance, or undersized cables carrying starting current. Always tighten terminals properly and replace corroded components.
