bghere Posted November 24, 2021 Topic Author Share Posted November 24, 2021 Ron this started with new battery draining! so I was told it was the BCM, got a rebuild ,for ebay, told it wasn't any good! returned it. In the meantime the mechanic put the old one back in, and kept trying to find the problem, when there today and he to me disconnected the HDM, there was no draw to the battery.

DAVES89 Posted November 24, 2021 Share Posted November 24, 2021 (edited) What's an HDM? Went back and read your prior posts. Headlight Control Module. Yes I have a couple. PM me if interested. Can't get back to you until next week as I am on vacation. Edited November 24, 2021 by DAVES89 Link to comment Share on other sites More sharing options...

It's normal for any Reatta to have some current draw when everything is turned off and the key is removed. There are tests here on ROJ in the how-To guides to determine if current draw is excessive.

Padgett Posted November 25, 2021 Share Posted November 25, 2021 HDM should not draw any when headlights are off. Link to comment Share on other sites More sharing options...
