How to check for parasitic draw. web parasitic draw test diagram 1 parasitic draw test diagram science abstracts essentials of paleomagnetism volkswagen new beetle how to diagnose and repair. web before parasitic draw testing it was the tried and true old test light method between the battery post and cable. normal amount of parasitic. Riveting stuff (yeah, the hours fly by ) this was current measured by direct connection (i.e. not with a non intrusive current clamp, the meter was in series with the negative battery clamp.) skip to 3:30 where the 'fun' starts. you hear some relays in bcm2 dropping and the current drawn drops accordingly.
3. conduct initial test. pop the hood and get in position. if the hood is equipped with a lamp, make sure to rig the pressure switch or pull the bulb to keep it from interfering with your test. Parasitic battery drain test method #1 current draw testing for parasitic battery drain. in a current draw test you watch for a drop in current as you remove each fuse from the fuse box. if you pull a fuse and notice the current drop to less than 50 miliamps, you’ve identified the circuit with the problem. 1. open the passenger door, manually move the latch on the passenger door to lock it. it clicks twice. make sure you push it all the way in. 2. open the glove box, tape the light button so the glove box light is off. 3. remove the fuse box cover, using your meter take a reading on fuse #28. Tip 1: easy battery drain testing with a multimeter. for our first tip, let's delve into the battery drain test using the multimeter and its ammeter function. the primary challenge with this method arises from having to disconnect the battery, potentially triggering additional issues and extending your diagnostic time.

Causing the high parasitic drain. testing set up to begin diagnosis of a parasitic draw, it’s important to properly set up the test. there are many things that can prevent the vehicle from completely going to sleep and passing the parasitic draw test. 1. road test the vehicle and operate all accessories to check for proper operation. 2. Step 2: disconnect the battery. pop the hood and disconnect the negative cable from the negative battery terminal. it is always best to do a parasitic draw test from the negative side so there is no chance of accidentally shorting should you test from the positive side. step 3: connect the multimeter.
