Normally a voltage drop would mean too much current but 220k and 150k is plenty of resistance.Double-check the resistors with a multimeter to make sure they really are that value (I know you're sure they are, but that's the symptoms...)
Yeah, that's something I checked previously. The values are well within the 5% tolerance.
Any possible alternative to a voltage divider with resistance that i might be able to get away with? Originally I setup a simple LED voltage meter in a project box and it did a great job. The connector for these stands has 24v for me to work with.
