How To Perform a Parasitic Draw Test - EricTheCarGuy This video has been a long timing coming and is one of the most requested things I get is about batteries going dead overnight so I'm very happy to finally bring you this video about the process of finding a parasitic draw which is a small drain on a battery above 50ma when the vehicle is shut off. Once you find the right fuse(s) the next step is to trace the components involved in that circuit till you find the source of the draw, you first start with a wiring diagram to give you an idea of where to start looking and then start unplugging things in that circuit to isolate the cause, it's quite scientific really a simple process of elimination. Here is a link to BBB's site that you can use to look up wiring diagrams for your application. Good luck and if you have anymore questions check the database on my website and if you don't find what you're looking for there then post your question to my forum, here's a link. --- Click below and Stay Dirty Visit me at Visit EricTheCarGuy Forum Visit my Facebook Page: --- Be safe, have fun, and stay dirty ETCG Due to factors beyond the control of EricTheCarGuy, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.  EricTheCarGuy assumes no liability for property damage or injury incurred as a result of any of the information contained in this video. EricTheCarGuy recommends safe practices when working with power tools, automotive lifts, lifting tools, jack stands, electrical equipment, blunt instruments, chemicals, lubricants, or any other tools or equipment seen or implied in this video.  Due to factors beyond the control of EricTheCarGuy, no information contained in this video shall create any express or implied warranty or guarantee of any particular result.  Any injury, damage or loss that may result from improper use of these tools, equipment, or the information contained in this video is the sole responsibility of the user and not EricTheCarGuy.
