On these maxi-scooters, the regulator is the culprit in most cases.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it correspond to my Shindengen SH689?\u003c\/strong\u003e\u003cbr\u003e\nYes. The 639110 corresponds to \u003cstrong\u003eShindengen SH689-DB and SH689-JB\u003c\/strong\u003e. It is the same component with the Piaggio reference.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow many wires does it have?\u003c\/strong\u003e\u003cbr\u003e\n\u003cstrong\u003e7 cables\u003c\/strong\u003e, pre-wired and terminated into \u003cstrong\u003etwo connectors\u003c\/strong\u003e — one red and one black \u003cspan style=\"color:#666;\"\u003e(observed from product photos)\u003c\/span\u003e. Three cables come from the alternator (three-phase), the others are ground, battery positive, and signals. If the connectors on your vehicle are different, \u003cstrong\u003econtact us for more information\u003c\/strong\u003e with model and year before ordering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I mount it in a different spot because the original one is inconvenient?\u003c\/strong\u003e\u003cbr\u003e\nBetter not. The regulator \u003cstrong\u003edissipates heat\u003c\/strong\u003e through its fins and needs the airflow of the original location. Mounted in an enclosed area, it will overheat and last much less.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy did the connector melt?\u003c\/strong\u003e\u003cbr\u003e\nBecause an oxidized contact increases resistance and heats up. It is the most common cause \u003cem\u003eand\u003c\/em\u003e consequence of the fault: if you plug the new regulator into a damaged vehicle connector, \u003cstrong\u003eit will burn out again\u003c\/strong\u003e. The vehicle-side connector must be replaced or redone.\u003c\/p\u003e","brand":"Piaggio","offers":[{"title":"Default Title","offer_id":58633514221916,"sku":"639110","price":49.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/3660\/0668\/files\/piaggio-639110-regolatore-tensione-12v-35a-beverly-mp3-x9-vespa-gts-1.png?v=1786545909","url":"https:\/\/www.moonbikesrl.it\/en-ch\/products\/piaggio-639110-regolatore-tensione-12v-35a-beverly-mp3-x9-vespa-gts-aprilia-gilera","provider":"Moon Bike S.r.l.","version":"1.0","type":"link"}
