The meter has its own LED display with voltage on the top row and current on the bottom, three digits each. Clamp it on, follow the steps, and read your parked car's draw.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is a normal parasitic draw reading?\u003c\/strong\u003e\u003cbr\u003eFor ordinary vehicles the ideal standby draw is about 20 to 50 mA, though it differs by model. Read it after the car has slept and you can see how your number compares.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long should I wait before testing?\u003c\/strong\u003e\u003cbr\u003eIt depends on your vehicle, because sleep time differs by model, so be patient. Switch off, remove the key, lock all doors, and give the car computer time to sleep before you read the meter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does my meter show 0?\u003c\/strong\u003e\u003cbr\u003eThe meter starts at 30 mA. If your car's sleep current is below that, it shows 0, which means no leakage. Readings above it show in amps, so 50 mA appears as 0.05 A.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill I lose my radio presets?\u003c\/strong\u003e\u003cbr\u003eThe test has you loosen the negative terminal, so jot down your radio presets first. Then follow the steps in order, and remove the tool before you reconnect the negative terminal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I start the engine during the test?\u003c\/strong\u003e\u003cbr\u003eKeep the ignition off with the key out. Starting the engine mid-test can burn out the fuse. Remove the tool first, then reconnect the negative terminal when you are done.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat if the fuse blows?\u003c\/strong\u003e\u003cbr\u003eThe red lead has an inline blade fuse holder. If the fuse is damaged, swap in one of the same rating. Keep the engine off during the test, since starting it can burn out the fuse.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it plug into the fuse box?\u003c\/strong\u003e\u003cbr\u003eIt works right at the battery with clamps and a clip, and shows your total draw. It doesn't name the circuit, so think of it as your first check on how much your parked car pulls.\u003c\/p\u003e","brand":"PrimyDeals","offers":[{"title":"Default Title","offer_id":49750660284571,"sku":"PD-sleepwatt-parasitic-draw-tester-1","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/1712\/7067\/files\/parasitic-draw-tester__p5_v1.png?v=1791476217","url":"https:\/\/primydeals.com\/products\/sleepwatt-parasitic-draw-tester","provider":"PrimyDeals","version":"1.0","type":"link"}
