OK.
Now connect input 1 on the inverter to +12V, the corresponding RGB color LED on the fixture should be OFF.
The corresponding LED on the inverter should be on.
Is this correct?

 

This is how the wiring is

 

does this help?

 

forgot to add negative in the drawing from psu to fixture

 

should be

 

The wiring looks correct.
How did the test from post 101 go?

 

I didnt understand 12v+ as the ones from the DMX box are all neg except the one with the question mark thats not connected, it is currently wired as the image. with all the RGBs on and no leds showingon the small connection board

 

it is currently wired as the image. with all the RGBs on and no leds showingon the small connection board

Are all the LEDs on the fixture ON?

 

correct

 

Now set all RGB from the DMX OFF.
Three of the LEDs on the inverter board should be ON and all LEDs on the fixture should now be OFF

 

just double checked all leds are on the fixture none are on on the board this is exactly how I started earlier on.
I just tried changing the small board as well in case it was faulty/damaged. all inputs on small board read 12v all outputs less than 1v. the fixture is being lit by the pos and neg from the 12v supply ignoring the RGB input completley. I believe the DMX positive currently not connected is required for the DMX box to do its thing. so sorry this is causing so many problems

 

all inputs on small board read 12v all outputs less than 1v.

That is what it should read but the 3 LEDs on the inverter should ON too.
Is the jumper on the inverter board in place?
Is there 12 volts on the inverter board?

 

yes not touched it

 

And you are sure the negative and +12 volts is connected to the inverter.
Can you measure the voltage across those two pins?

 

11.86v

 

I believe the DMX positive currently not connected is required for the DMX box to do its thing. so sorry this is causing so many problems

Do you mean the +12V output on the 4 pin connector?

 

no on the invertor

 

Where on the inverter, I'm confused now.
I thought everything was connected as shown in post #105.

 

sorry yes it is connected as the image the 12v from DMX is not connected, so its 11.86v at the invertor from the psu

 

so if the DMX box positive (the one with the question mark in the image) is not connected how does the RGB signal activated as the circuit isnt complete on the DMX box?
