Diagnostic Tips: Here is a simple test you can perform to check your alternator. With your battery fully charged, start your vehicle.Turn on your lights and heater fan. Perform a voltage test from the positive to the negative battery post. The voltage reading should be between 13.0 and 15.3 volts. If less than 13.0 volts and your battery connections and alternator belt are good, chances are your alternator needs to be replaced. If the reading is above 15.3 volts, you probably have a bad voltage regulator (sold separately).\u003c\/p\u003e","brand":"Powermaster Performance","offers":[{"title":"Default Title","offer_id":48420211065044,"sku":"S7102","price":252.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/2522\/7988\/files\/S7102_main-01.jpg?v=1785798775","url":"https:\/\/muscleroad.com\/products\/1963-71-externally-regulated-70-amp-10dn-style-alternator","provider":"Muscle Road Performance Design","version":"1.0","type":"link"}
