What is the normal range of battery drain with ignition off?
What is the normal range of battery drain with ignition off? Assuming the car is in prefect order, the only drain on the battery, when the ignition is off, is from ancillary systems. Does anyone have an estimate of what the drain is from:
What causes a car to draw power from the battery?
Learn more… If your vehicle is drawing power from the battery and all of the lights and other electrical components are off, you might have a parasitic battery drain (or draw). Luckily, you can usually find the cause of a parasitic draw yourself. Start by connecting a digital multimeter to the negative battery terminal of your vehicle.
Do you need a multimeter to check battery draw?
To troubleshoot the current draw, you need a multimeter that can perform current reading. The multimeter should be able to read at least a 10 amp current. Multimeters are very inexpensive and be purchased for under $20.
How to get rid of negative battery drain?
Remove the negative battery cable from the negative battery terminal. Find the negative cable, which will be marked with a minus sign (-) and may have a black cover over it. Remove the cover, if applicable, and use a wrench to unbolt the negative cable from the terminal.

How does parasitic battery drain work on a Dodge Ram?
You don’t do an Amp draw across terminals, you use a CT around the positive cable. He is talking about voltage drop as without the truck running and the power being used the battery’s voltage is going down resulting in a dead battery. Click to expand… What he described doing in the quote above is an amp draw test (parasitic drain).
Can you turn off parasitic draw test switch?
NOTE: Do not turn the parasitic draw test switch to the OFF position with the engine running. Damage will occur to the vehicle’s electrical system. The test switch must be in the ON position when removing the fuses in order to maintain continuity in the electrical system.
