As a result the high tension current  averaging 30 000 volts  shorts out from the tip of the overlength rivet  through the reduced thickness of more conductive plastic via the spring clip on the underside of the rotor arm to earth out down the distributor shaft. Result - no sparks at the plugs. These Distributor Doctor rotor arms are modelled on the original  dependable 1960's design  but made from modern materials on the latest machinery to very close tolerances. These arms will not let you down. The integrally moulded brass inlay dispenses with the troublesome rivet used on most versions which is known to short circuit. The increased insulation properties of the body makes them suitable for use with high voltage coils \u0026amp; electronic ignition kits. The spring steel clip on the underside  in conjunction with a revised internal tolerance assures a really snug fit  even on old \u0026amp; slightly reduced diameter mountings.\u003c\/span\u003e\u003c\/p\u003e","brand":"MG Sales \u0026 Service","offers":[{"title":"Default Title","offer_id":37829632387,"sku":"872-785","price":33.06,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1329\/9201\/products\/872-785_1.jpg?v=1753154037","url":"https:\/\/mgsales.com.au\/products\/872-785","provider":"MG Sales \u0026 Service","version":"1.0","type":"link"}
