The rotor winding in this alternator is specified to measure 1.4 to 3 ohms resistance across its two leads (red-tagged and blue-tagged wires) when tested with a multimeter. A reading outside that range indicates rotor winding failure, per the Wacker Neuson G25 troubleshooting procedure for AC power generation. Symptoms prompting rotor inspection include abnormal or absent AC output from the generator.\u003c\/p\u003e\n\n\u003cp\u003eTesting requires the generator to be shut down, the rear baffle and generator cover removed, and the engine rotated as needed to access the rotor winding wires before disconnecting and measuring resistance. If the rotor has failed that test, this is the correct replacement rotor for restoring proper alternator function.\u003c\/p\u003e\n\n\u003cp\u003eCompatible models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWacker Neuson G25 (Standard T4F, Cold Weather T4F, Custom T4F, Extended Run T4F)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43398967525424,"sku":"WACKER-5100062013","price":3249.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5100062013.jpg?v=1784082891","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-main-rotor-5100062013-for-g25-generator","provider":"CCE Industries","version":"1.0","type":"link"}
