1. Why is my engine failing to shut down with the ZPTR-BS-40-120 installed?
Common issues include a burnt internal coil or a stuck plunger due to fuel contamination. Check if the 24V signal reaches the solenoid. If the ZPTRBS40120 coil resistance is outside standard range, it requires immediate replacement.
2. Can I use a 12V version for a 24V ZPTR-BS-40-120 application?
No. Using a 12V solenoid on a 24V system will result in immediate coil burnout. Always verify your machine's voltage before ordering the ZPTR-BS-40-120(24V).
