Parasitic Draw Not Fuses

Parasitic Draw Not Fuses - Web once we identified which of the higher amperage fuses were carrying the parasitic load (draw) then we’d pull those lower amperage fuses that were protected by it one at a time. If the multimeter indicates excessive draw, begin to track down the problem by pulling fuses and removing relays one at a time until the draw goes away. Disconnect that wire from the battery and see if. Web to identify potential culprits causing excess parasitic draw, pull out fuses one by one while monitoring changes in meter readings after each removal and consult your vehicle's owner manual to investigate further. Once a parasitic draw was seen, you pulled the fuses, components or relays until the offending current draw disappears. Web start pulling out each fuse until the sleep current is below 50ma. They do require you to work with a live electrical circuit, though. The complaint is frequently that the engine won’t start after a couple of days of sitting because of a dead battery. I kept the current at the stable ~0.09a parasitic draw and pulled individual fuses to determine which circuit affected the current. Web a parasitic draw test is required when a vehicle battery becomes discharged with the key in the off position.

Web Buy Now There Are A Couple Of Ways To Pinpoint Which Circuit, Component Or Module Is Causing The Battery To Discharge.

With the amp meter in series with the batt cable, either one, and wait until after 16 minutes and the meter measure about 140ma, then start pulling each fuse to see which one to cause current drop below 50ma. Web using a voltage drop test on a fuse to check parasitic draw. Any input would be greatly appreciated. Web defective modules are common causes of parasitic draw problems.

Web Parasitic Draw Tests Don't Involve Big, Toothy Tools Or Blow Torches.

The complaint is frequently that the engine won’t start after a couple of days of sitting because of a dead battery. Web start with your underhood fuse panel. This test will show how to quickly pinpoint the source of the draw using voltage drop across fuses. Web i did find a tsb that says that the computer might cause a draw only after it has been turned on and then off, so disconnecting the battery to set up the test gets rid of the draw if it’s that.

Once A Parasitic Draw Was Seen, You Pulled The Fuses, Components Or Relays Until The Offending Current Draw Disappears.

I kept the current at the stable ~0.09a parasitic draw and pulled individual fuses to determine which circuit affected the current. Web pull out the fuses one at a time while watching the multimeter reading. Web the temp fix was to remove the fuse that powers the clock and radios memory circuit on my truck. Some of the more nerdy among us folks would install an ammeter in series instead of a test light.

There Is A Chance Of Getting Shocked Or Causing.

Use a fuse puller to remove the fuses, starting with the ones with the smallest amp ratings and working toward the ones with the highest amp ratings. When a car has battery drain proper testing is vital to finding the problem. It may take a some time for the parasitic drain to start after you reconnect the battery as all the circuits reset after the power loss from disconnecting. I started in the engine compartment fuse box, where the only fuses i found flowing current were those powering up the pcm and bcm.
