Hey all, so I am dealing with a parasitic draw that is killing the batter in under 2 days, but I cannot track it down!
here is what I have tried:
1- verify draw by removing battery ground and running multimeter from ground wire to battery. Was not getting any reading but every time I connected the negative lead there was some sparking so it was surely pulling amps. I assumed multimeter bad.
2- switched to using an amp clamp. I clamped the negative wire right before the battery and got a reading of 610 miliamps. To verify the clamp was working I flipped on the headlights to see if amps spiked on meter - they did.
3- I waited 30 mins then did a voltage drop test on the under hood fuse panel. I couldn’t find a single fuse that had any voltage drop. So make sure meter was working I turned on headlights and found voltage drop on that circuit.
4- after waiting again I voltage drop tested the inside fuse box and again, nothing drawing power. So then I got annoyed and removed all fuses and relays from the engine fuse block, all fuses relays and wires from the inside fuse block, and everything from the instrument panel fuse block. On top of that I removed commonly problematic things like the radio, hvac controls, instrument cluster and drivers door lock switch. The draw is still there!
I am getting to my whits end with this. What can be left? Starter solenoid?
