The kit is designed for many 70cc–125cc Chinese-model 4-stroke quads and includes clear connectors and zip ties to simplify routing. Before buying, verify your ATV’s stator and CDI type against the product images and wiring diagram to ensure compatibility.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this kit restore my ATV’s ignition and charging?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit replaces the core electrical elements: stator for power generation, CDI for ignition timing, ignition coil for spark, and a rectifier\/regulator to control charging voltage. When installed correctly, those components reestablish spark and charge to the battery and electrical system.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncludes stator (magneto) and 5-pin AC CDI box for ignition control\u003c\/li\u003e\n  \u003cli\u003eIgnition coil and A7TC spark plug for reliable spark delivery\u003c\/li\u003e\n  \u003cli\u003eRectifier\/regulator to stabilize charging output\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich ATV models and engines is this wiring harness compatible with?\u003c\/h3\u003e\n\n\u003cp\u003eThis wiring harness is built for many small Chinese-made 4-stroke ATVs with 70–125cc engines.

This EOPOAYI kit is aimed at owners, mechanics and small-vehicle shops that need a one-box electrical replacement for 70–125cc Chinese 4-stroke ATVs like Tao Tao and Coolster. It’s ideal if your bike has a failed stator, coil, CDI or regulator and you want matched parts to restore ignition and charging without sourcing components individually. If you’re unsure about compatibility or lack electrical experience, have a qualified technician confirm fitment and perform the installation to avoid damage from incorrect wiring.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this harness fit my Tao Tao 125cc quad?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Likely yes if your Tao Tao uses a 4-stroke 70–125cc stator\/CDI layout; confirm the stator and connector images match your ATV.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I install this kit myself?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: You can if you have wiring experience and a diagram, but professional installation is recommended to avoid polarity or connection errors.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"EOPOAYI","offers":[{"title":"Default Title","offer_id":48086146711710,"sku":"B0FS12XLRX","price":49.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/eopoayi-harness-front-view.jpg?v=1785886684","url":"https:\/\/northtrailauto.ca\/products\/eopoayi-complete-atv-wiring-harness-kit-for-70-125cc-tao-tao-coolster-includes-cdi-stator-rectifier","provider":"North Trail Auto","version":"1.0","type":"link"}
