The moonlight driver lights up two boards at a time. All of the boards were tested with that. And, the meanwell drivers will light up a few of the boards at a time when dimming power isn't supplied, but not everything in the string. One of the drivers will light five boards and the other one will light four (these are very dim, however). There are seven boards (14LEDs) on the RB series. There are six boards (12 LEDs) on the CW/NW string. According to the specs, the drivers will run 8-14 LEDs. The two blue boards are on a the little moonlight driver, and they work (at least something works!).
I'm thinking it has to be an issue with the apex dimming cable splice. The Meanwell drivers supply power (one supplies 24V and the other at 16V).
I reviewed the "Unofficial User Manual", and followed the instructions in that. I also consulted threads in the Neptune forum on RC. I'm 99% sure that the Apex and/or VDM aren't the issue. But, if the 9V test works, the issue will have to be with the original splice, the Apex and/or VDM. If it works, I'll just try hooking up the Apex/VDM again to see what happens. If it doesn't work with the second splice to the Apex . . . then it is the Apex.
I used the 3M Scotchlok connectors on the splice: which was dumb. I should have verified that everything worked before I used those. Now I have to cut those out, which I have to admit that I'm trying to avoid doing. The connectors are cheap, but I hate to lose any wire length.
I don't think there is a potentiometer in the house. I should pick one up. I just didn't realize it would be a good thing to have for troubleshooting purposes.
It has taken three Modular LED orders to get to this point. I'm hoping there won't be a fourth. Of course, I've totally modified the original kit . . . so the number of orders reflects my level of preparedness and understanding: not Martin's kit.
