How To Fix an Electrical Drain on your Car Battery for Porsche 993. (Two methods - DIY)

Hi Everyone, The battery has been going dead in our 1995 Porsche 993 and in this video I go over a couple methods you can use to find electrical parasitic draws in your car’s electrical system. The first method is for older cars that you are fine with removing the negative battery cable and the second is great for newer cars where disruptions to power can cause big headaches. All you’ll need is a good Volt/Ohm/Amp multimeter and a little critical thinking. You’ll want to consult your owner’s manual to locate all the fuses and electrical components for your particular car. The first method involves removing the negative battery cable and splicing in an ammeter to directly read the parasitic current draw. By removing fuses we can directly see just who is causing all the fuss. The second method involves measuring the voltage drops across all the fuses. All fuses have some small resistance and if there is a current, we will see that effect in a voltage drop across the fuse terminals according to Ohm’s Law (V=I*R). I provide the resistance for the popular fuse sizes in the video so you can use I=V/R and calculate the approximate current, but if you would like to download a neat chart, I came across this site: http://info.powerprobe.com/fusechartsdownload Knowing your voltage across the fuse and its size, you can use the char to read the current flowing through the fuse. Pretty neat, huh? I also get out my handy-dandy Solar battery tester to make sure we have a healthy battery to begin with 😊 Tools and parts: • Solar BA5 battery tester/checker: https://goo.gl/dH6uoR or Solar BA7: https://goo.gl/x84nXy) • Large Multimeter: Cen-Tech 11 Function Digital Multimeter with Audible Continuity: https://goo.gl/vazi35 • Small Multimeter: Velleman DVM850BL-VP Digital Multimeter with Backlight and Protective Holster, 3-1/2 Digit, 5.4" H x 2.7" W x 1.2" D: https://goo.gl/GVs26k • Driew Double Ended Leads Test Clips Crocodile Alligator Jumper Lead Set Alligator Clips Connector 10 pcs Pack (50cm,5 colors): https://goo.gl/YNaDuk • Tools to remove your negative battery cable.
