Under factory set condition, whilst the vehicle engine is running the relay expects to see a voltage exceeding 13.5V; when this voltage is reached and maintained it will change its state to a closed condition, supplying voltage to the auxiliary unit. When the voltage of the vehicle battery falls below 12.9V will it disengage the supply, so on a vehicle with a healthy battery it is normal to see the supply maintained to auxiliary source for a period of time after the engine is switched off. Adjusting the pot on the top of the device will vary the voltage the unit opens and closes the relay contacts.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIs it safe to use on a stop\/start vehicle?\u003c\/em\u003e\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eYes, the relay is directly connected to the battery so the stop\/start technology will be bypassed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Maypole","offers":[{"title":"Default Title","offer_id":58531817587069,"sku":"MP2883","price":22.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0566\/2529\/9515\/files\/2883B_1.jpg?v=1786628665","url":"https:\/\/www.autosave-scotland.co.uk\/products\/30a-self-switching-dual-charge-relay","provider":"Autosave Components","version":"1.0","type":"link"}
