DocBrown86 Posted December 12, 2017 Share Posted December 12, 2017 I have used this controller for 3 years now, and suddenly this year when I hooked up the RGB Floods (4 of them) only the reds are lighting up... I am getting 12V to all the colors at the lights. I even used a new fixture to be sure I didn't fry them all. Any thoughts? It's always worked great and the controller has always been indoors...

k6ccc Posted December 12, 2017 Share Posted December 12, 2017 That seems to be a very unlikely failure mode. I know you have used this arrangement before, but verify the wiring (especially if it's not a quick disconnect for all four wires at once). Try it with the Hardware Utility to make sure a sequence did not get re-arranged. Link to comment Share on other sites More sharing options...

The CMB24 puts GROUND on the R G and B. +12V feeds the floods. If you mis-spoke, then take a jumper wire and connect 1 end to V- and touch the other end to the screw of each G and B (and R) with the plug connected CAREFUL TO NOT TOUCH THE 12+ If the colors light, you may have fried the MOSFETS. (overloaded with multiple floods? or shorts to 12V+) Edited December 12, 2017 by TheDucks Link to comment Share on other sites More sharing options...
TheDucks Posted December 12, 2017 Share Posted December 12, 2017 Nother Idea. Check your wires that the INSULATION is not under the screw terminal Link to comment Share on other sites More sharing options...
PhilMassey Posted December 13, 2017 Share Posted December 13, 2017 If you need a quick portable way to test dumb 12V rgb lights, get a 9 V battery and attach leads to the terminals. Link to comment Share on other sites More sharing options...
