1999 ML 430 with 4 amp parasitic draw. Did amp draw test pulling each fuse, as well as relays, in engine compartment fuse box without finding draw. Doubled checked by performing voltage drop test across all fuses. Is there another fuse block that is hidden? Already checked passenger kick panel. Any ideas of what to check next? Thanks for any help that can be provided. Vehicle is completely stock with no recent modifications or prior electrical problems.

None of the fuses is causing the parasitic draw. Checked by pulling each fuse and relays. Also did voltage drop test across all fuses with no drop detected. Today disconnected driver’s seat module. No change. Looks like the drain is coming from a circuit that is on when the ignition is off.

Thanks for the video. That’s the voltage drop test I already performed.. No voltage drop across any of the fuses. That’s why I believe the draw is on a non-fused circuit.
