Mar 04, 2020 · This is right out of my service manual. It is based on battery reserve capacity, divided by 4. (or, amp hour rating divided by 2.4): "The parasitic current drain should not exceed this number. Example: If a battery has a reserve capacity of 100 minutes (60A/H), the current drain should not exceed 25 mA." Aug 24, 2018 · I have up to an amp of parasitic draw that goes away if I pull fuse #16 in the main fuse box under the hood which is labeled "Back Up". I see from a diagram I found online that that fuse controls an enormous number of sub circuits. I tried pulling out each fuse one by one by the driver's foot... So today I finally got to do my Parasitic draw test on my 2003 Duramax. I set the Multimeter to 20M on the DC amps and the initial reading was 2.35. Started pulling fuses and when I pulled the radio fuse it dropped to .85 so I am assuming that is the culprit or at least a start. I decided to see...

When your car battery goes dead overnight, usually either the battery is at the end of its life span, or you left something on, such as a light. Occasionally something is drawing power that’s not of your doing. This is a parasitic draw, and it can cause the same result as leaving the headlights on: a dead battery in the morning. Car amplifiers can produce more power to deliver increased output and enhanced sound at greater volumes. To ensure the best setup for your car, consider car stereo installation from Geek Squad®. They can help you find the ideal components for your vehicle and properly connect everything.

  9. If you are comfortable doing this, disconnect the power wrie from your battery and put a voltmeter set on amp between the power wire and your battery. It should read 0 amp draw but if it is higher then you can see how much. Then disconnect amp and recheck...unfortunately troubleshooting is a time-consuming process.
  10. Keep the ignition off. If the bulb lights up it tells you that you are pulling current through the bulb. This is your parasitic draw. Now pull one fuse at a time and watch the bulb, when it shuts off or dimms (What's the plural for Dim?) it tells you which circuit is causing the draw.
  11. I did do a parasitic draw test which was.665 amps. When I pulled the stereo/amp fuse the draw went away and dropped to.050 amps. I then tried disconnecting the amplifier and the draw went away. Same results. The amp has its own power supply as does the radio. The amplifier from what I see in the schematics that I got does have a relay.
  12. Find solutions to your parasitic draw question. Get free help, tips & support from top experts on parasitic draw related issues. 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.

Dec 07, 2012 · First of all, your car should have a “normal” parasitic draw of 40-60 mA with everything off and the key out of the ignition (a common testing mistake), and you are obviously way over that. That said, you should also note that some systems stay active for a short period after the car is first switched off, so you sometimes need to let it ...
  16. Here's how I go about it for parasitic draw - you should give it a try, it's not too bad. You accidentally created this post in the `cars for sale` forum instead of the GRM general though. Maybe message a moderator and they'll move it for you. Good luck!
  17. Jun 18, 2019 · With the multimeter in series with the battery and the car off, I was getting 0.1 Amp draw. I started pulling fuses and BOOM. Pulling the dome light fuse dropped the power draw immediately to zero. I unplugged all the dome lights in the truck and it was still drawing power for some reason. Turns out there's all kinds of fun stuff on that circuit.

  19. Mar 14, 2016 · I have a 2010 Subaru Forester (non-turbo) that has been having a parasitic draw problem for the past few (cold) months. It’s enough where once in a while an overnight is enough to drain the battery low enough that the car won’t start. Anything longer than one night is almost assured to do so. The car has a ~100 milliamp draw.
  20. Apr 05, 2011 · Sounds to me like the amp is having some kind of trouble sending power to the woofers & subs (being that they are the units that draw the most power and your tweeters continue playing). An interesting test would be to measure the output at the amp (via multimeter) when playing normally and then under the conditions that cause it to drop.
  21. Using a low amp clamp and a digital volt ohm meter (DVOM), confirm there is a parasitic draw. Note the amount of draw you find. Our subject vehicle has a parasitic draw of 60 milliamps.

  26. To get a true parasitic draw, you would need to open the hatch and block off the switch that activates the door open signal, then leave the hatch open for 15 or 20 minutes until all the car's systems go to sleep. After that, approach the car without the Smart Key on your person and you should get what is the true parasitic draw.
  27. on my amp draw the MSM would take about 30-40 seconds before the draw would stop, another 2 mins for other control modules to go to sleep after that. I use an amp clamp, when you find the issue sometimes when removing the battery to install the amp meter in series, the issue sometimes goes away. so its too hard to find or move to another circuit.

  19. Choosing the Right Wire Gauge for Amplifiers A topic that seems to cause a lot of confusion in car audio is how to choose the right wire gauge for the amplifiers. Amplifiers require voltage and amperage (remember power is equal to voltage multiplied by current).
  20. Jul 05, 2018 · Yes, it is possible that pulling 15A F79 'curing' your problem is an indicator that one or more of the components or circuits fed by that "hot at all times" fuse has a parasitic drain, possibly a short-to-ground that is not energetic enough (low volts/amps) to cause the fuse to blow.
