How To Perform a Parasitic Draw Test - EricTheCarGuy
http://www.ericthecarguy.com/
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.

I get a lot of questions via email and over at the forum about the steps to take when you encounter a performance issue like my Subaru's hesitation issue and I often feel like I sound like a broken record when I cover the basic steps that I cover when encountering a situation like that. My main point here is that if you have a performance problem and you're going to throw parts at the problem start with the basics before you to off and start replacing sensors that you suspect are a problem, if you don't have evidence of a faulty sensor then don't start there start with the simple tune up items and check for vacuum leaks and air leaks as I've shown here and I believe you'll have better results and save yourself some money in the process. In short the rule of KISS applies, Keep It Simple Stupid.
If you have questions about your own engine performance issues head over to my website and either ask the search function or ask the forum, we'd be happy to help.

How To Test Relays- EricTheCarGuy
How To Test Relays- EricTheCarGuy
How to test relays is a video about just what it says. Every once in a while you need to test a relay and when you do it's important to check it thoroughly, if not you may think it's good and it's not, just because it 'clicks' doesn't mean it's good because that's only part of the equation. Yes you can swap it out with a known good relay and that will save you time but if you don't have a known good then this test should do the trick for you. This video is also a good way to get to know what's inside a relay and how it works so if you're curious about that this would be a good video to watch.

Finding a active short
A fuse that keeps on blowing is an active problem and can be difficult to find. However if you use these steps, you should be able to locate and repair it.
3 Ways Of Finding The Cause Of Key-Off Battery Drain (Parasitic Draw)
(This is the full-length version of an earlier video we shared. This version shows additional methods, all of which can be used together to make the job of isolating the cause of key-off drain much simpler.)
Your customer has their car towed to your shop after it wouldn't start that morning. You check the battery and see it's pretty low, and you do what's correct. You charge the battery and test its condition.
It passes with flying colors.
You reinstall the battery in the car and the car starts immediately. You check the starting and charging systems and still no culprit is uncovered. Being the professional auto service technician you are, you know there is only one other logical explanation. Something on the car is not turned off when it should be and it's draining the battery down to a point there isn't enough left to spin the engine.
But finding the parasite that is causing that drain can pose a few challenges. Increasingly common are electronic control modules that insist on staying on, or "awake" when they should time out or "sleep". The traditional method of monitoring current while removing fuses one at a time can often cause the offending module to reset, and the problem to temporarily disappear.
One method you can use to find the cause of a key-off battery drain without intruding on the circuits is to measure for the presence of voltage drop across the vehicle's fuses. The fuse is a resistance, isn't it? And according to the laws of electricity, voltage will be used to overcome that resistance resulting in a drop across the fuse we can measure with our meter.
And that's only one way you can catch the parasite without having to open the circuit.
In this edition of The Trainer, we'll show you how to test for a "key off" battery drain using a few different methods; first, using the ammeter and voltmeter of your digital multimeter (DMM) and second, using an amp clamp and a digital storage oscilloscope (DSO). Knowing a few different ways to test for these parasites should make those challenges a bit easier to handle! Click this link to subscribe to Motor Age! http://bit.ly/MA_YT_freesub

I'm pretty sure this one is going to draw some fire but I was asked and I've taken some time to respond in kind, in fact this is take 3 of this video, the first take I liked but then I read the Honda article and thought it really fit with the topic so I rerecorded it with some of that article included unfortunately there were technical issues and that video was scrapped so I then taped this one so by the time I got to it I'd already covered this material 3 times. That said I think it's an interesting topic and I look forward to your responses as I'm sure many of you have plenty to say on the subject, I'm already thinking about the Re: video to go with this.

Once again I team up with BBB Industries to bring you the basic steps in starter diagnosis. If you suspect a bad starter you might want to run through these checks before you commit to get a new one, you just may find that you don't need a starter but rather some other issue is causing the no start.
