A car left standing for three weeks rarely starts. It is not that the battery is bad: it is the alarm, the ECU, the stereo and the telematics unit drawing current the whole time. A cut-off switch isolates the battery from the rest of the vehicle in one movement, and you find it as you left it.<\/p>\n
Any work on the electrics starts with \"disconnect the negative terminal\". With this unit, no more 10 mm spanner and no more terminal put back crooked: a quarter turn of the knob and the circuit is open.<\/p>\n
With the circuit open, the car will not start, whatever the method. It is rudimentary, and it works \u2014 provided the knob is within reach and the bonnet release is not left accessible.<\/p>\n
This type of cut-off switch fits onto a a standard car battery terminal<\/strong>. Check that your bonnet leaves enough height above the terminal: on some very tightly packed engines, a few centimetres are missing. On a recent vehicle, be aware that a prolonged disconnection loses the stereo presets and sometimes the comfort settings.<\/p>\n A switch that fits onto the battery's negative terminal and cuts the whole circuit with a quarter turn. For a vehicle that stands for long periods, a van, a motorhome, a classic car \u2014 or to work on the electrics without undoing a terminal with a spanner.<\/p>","protected":false},"featured_media":2026,"template":"","meta":[],"product_brand":[],"product_cat":[141,134],"product_tag":[],"class_list":["post-1048","product","type-product","status-publish","has-post-thumbnail","product_cat-antivols-voiture","product_cat-securite-et-surveillance","first","instock","shipping-taxable","purchasable","product-type-simple"],"yoast_head":"\nWorth knowing<\/h3>\n
