It becomes noticeable if the car sits for 2 days or more. It’s draining my plannano bank. It also did it when I ran Headways. I’ve checked numerous items then I found that I need to check the alt and make sure it’s not bleeding DC. So I ran a diode test on the alt the normal way and the meter reads the normal .564 but once I swap the leads to see if it’s bleeding the meter then reads 2.994. I checked the stock alt and it does not bleed like that. I then decided to test another spare 250amp alt from another vendor that I have as a back up & it did the same thing, failing the test. Is this normal for H/O alts or do I really have 2 bad H/O alts?</p></blockquote><p></p>
