SOURCE: parasitic draw on battery how to check on car with

You will be able to help diagnose the problem by pulling fuses. Take a volt meter and put it to oms. Disconnect the positive battery cable. Put one end on the positive battery termanal and the other on the cable. Note the oms. Now, pull one fuze at a time until the oms drop considerably lower than before you pulled the fuzes. Thats the system that is drawing the power. Once you know the system you can track it down further. It could also be your altrenator. Disconnect it too and measure the oms before and after. take your time and do one system at a time noting the oms before and the oms after. My quickest guess it it is either your altrenator or your radio. Please note, you will have some "draw" no matter what because your clock radio or door lights will draw power. If you want to see this, test the oms with the doors closed and then test with the door open. The oms number will be higher with the door open.

If you don't have a volt meter, you can always test one fuze at a time over night. That would take considerably longer tho.

SOURCE: xg300 parasitic draw, located the 2 fuses that have the draw on them, how do i fix it

parasitic draw should remain at 50 milli amps or less or .05 amps this needs to be checked with an amp meter with the battery terminal disconnected and the power drain going through the amp meter keep in mind the circuits your testing may take up to an hour or two to fully go to sleep there is no easy way to test these multi circuits it takes years experience to troubleshoot these

Engine will not start

It sounds like you have a parasitic draw on your battery, without wiring diagrams, and a good understanding of electrical systems andsub systems, finding and fixing the parasitic draw is going to be impossible. You may be substantially better in the long run taking your vehicle to a shop, and having them diagnose the cause of your parasitic draw.

Sounds like you might have what's called a parasitic draw on your battery. Parasitic draw is an electrical component staying on after you turn the car off (that isn't supposed to be staying on) and draining the battery over night. This can be caused by a multitude of things- the light in the glovebox staying on, an aftermarket accessory incorrectly installed to your vehicle, or malfunctioning, a factory component in the car malfunctioning and staying on, a power seat switch stuck on... the list goes on and on. The easiest things to check would be your dome lights, trunk lights, sun visor lights, glove box lights, and seat switches. Make sure the lights are all off after you take the key out and close the doors. Make sure none of the power seat switches are stuck on. If you can't find anything checking the lights and seats, you're going to need a digital multimeter connected to the battery to measure amps, to measure the actual parasitic draw. Once you establish how much parasitic draw there is (30 MilliAmps or less is acceptable), you're going to need to start pulling fuses one at a time to find out where the parasitic draw is coming from. When you pull a fuse and the parasitic draw on the meter goes away, you've isolated the circuit. Then you'll need to find what on that circuit is using power when it shouldn't be.
Good Luck :)

Does a 2001 VW Beetle Turbo need to have a charge at 12.6 volts to conduct a parasitic draw test? I am told by a repairman that he cannot find out what is going on until I get a new alternator, batter

this is not true, a parasitic draw can be found with the battery in any state of charge, yhe purpose of this test is to find out out what is drawing current, meaning amperage from the battery and at what rate. take this to a certified mechanic, should be easy to find with the right tools.if you need more help get back to me. please rate my fix as i stive to be the best Thanks Ray
