class=\"obdm-n123-note\"\u003e\n\u003cstrong\u003eImportant Compatibility Note:\u003c\/strong\u003e N123 is a conventional 12V gasoline-engine xenon timing light, not a digital RPM\/advance-angle meter. It is not intended for diesel timing or 24V power input. Some modern coil-on-plug ignition systems lack an accessible spark plug lead for the inductive clamp. Always check engine compatibility and follow the manufacturer's timing procedure. Keep cables away from hot or moving engine parts.\u003c\/div\u003e\n  \u003cdiv class=\"obdm-n123-faq\"\u003e\n    \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n    \u003cdetails\u003e\u003csummary\u003eDoes the OBDMonster N123 work on classic cars?\u003c\/summary\u003e\u003cp\u003eYes, it is suitable for many classic gasoline cars with a compatible 12V ignition system, accessible spark plug lead and timing marks.\u003c\/p\u003e\u003c\/details\u003e\n    \u003cdetails\u003e\u003csummary\u003eCan it check 2-stroke and 4-stroke engines?\u003c\/summary\u003e\u003cp\u003eIt is designed for compatible 2-stroke and 4-stroke gasoline engines.
