Frequently Asked Questions
How do I test a Westwood ignition switch?
Test ignition switches using a multimeter set to continuity mode, checking that circuits close between proper terminals in each key position (off, run, start). Replace switches showing no continuity or incorrect terminal connections.
Why won't my Westwood start even with the key turned?
Non-starting with key turned indicates faulty ignition switch contacts, corroded switch terminals, or disconnected wiring harness behind the switch. Check for 12V at switch output terminals when key is in start position.
Can I bypass a Westwood ignition switch?
Bypassing ignition switches removes critical safety interlocks and isn't recommended; however, temporary jumper wires between switch terminals can diagnose switch failures. Replace faulty switches rather than permanently bypassing safety systems.
What causes Westwood ignition switches to fail?
Ignition switch failures result from corrosion on brass contacts, worn internal components from repeated cycling, moisture penetration into switch housing, or loose mounting allowing excessive vibration. Plastic switches are particularly prone to contact wear.
Do Westwood ignition switches include safety circuits?
Yes, Westwood ignition switches integrate with safety interlock systems preventing starting unless seat, brake, and PTO switches show proper positions. Faulty ignition switches can prevent starting even when all safety switches function correctly.
