    Umnitza ORION V4 Angel Eyes install, now causing battery drain

    Hey all, so I just installed my new Umnitza ORION V4 angel eyes. They look fantastic and function properly. However, after I installed them, I'm getting a short or drain somewhere that's draining my car battery really fast.

    I feel like the culprit is a short somewhere. When I connect my portable auto battery charger, it too looses juice pretty quickly and then I have to recharge that too.

    I have the white trigger wire from the angel eyes harness soldered to the accessories wire in the ECU housing (red wire with white stripe and gold patches). The blue wire coming out of the harness is taped at the end to ensure it isn't touching anything. Each white wire coming out of the angel eye drivers is soldered to their respective grey-green wire going to the low beams.

    Again, everything seems to work correctly. Angel eyes come on bright and steady with the accessories, and when I turn the headlights on they dim properly.

    No bare wires are exposed, everything is securely wrapped with electrical tape.

    How might I go about finding the short, or have I got my install wrong somehow?

    EDIT: When I remove the positive connection for the harness from the battery post, it still seems like there's a problem. Issue with accessories wire connection maybe?

    With the car off, voltage across the battery drops fairly quickly. Tried the parasitic current test but my multimeter did show any current being drawn (sanded my negative battery post a bit and everything).

    What happens when you pull the relay out from the harness? Does the drain stop? Inspect the connections to the plug that go to the relay as well.

    Any pictures of the wiring?

    Tried the car again this morning, after it had been sitting overnight.

    Before cranking battery read 12.55V. Hmm!

    Started easily.

    Perhaps it was an anomaly yesterday? Could be the battery is on the fritz...it /is/ one of those AAA roadside assistance batteries (probably 5 years old as well). Last owners of this car were not kind to it. New (and better) battery is on the list!

    Glad it worked. New battery not a bad idea at all.
