21SA RGB lights not working.

[larry_arizona]

Correction, there is a second RGB controller for in boat and speaker lights.


What’s strange is all RGB’s are dead including the underwater liquid Lumens. the underwater liquid Lumens have their own RGB controller.

Seems odd both controllers are not working.

Also measuring 12v to each RGB controller.

If both in-boat and underwater LEDs work in sync, then it could make sense that both are not working, as the commands comes from the Vision. I also think that the RGB signal to the LL box, would come from the ITC controller.
The LL OEM components may be different, but all their other power boxes ive handles, had an ON/OFF switch. But this would only power off the that controller, not the other controller.

Is the LL system CANBus also? It appears from what I looked up, LL is an on/off controller and I would question how it has 12V and not working.

Did a ground cable come loose? CANBus cable smashed behind a panel. CANBus cable become unscrewed from vibration. Can you check these for voltage? CAN+ 1.7V CAN- 0.7v

Not sure you want to chase all these down. Also, not sure how long the dealer would have to find the issue. Most service shops are backed up.

Logic tells me that the vision screen is not sending the signal to turn on either RGB controller.

The LL has a red and black wire to a terminal block on the controller, 12V across that block.

Rain forecast for all next week, it’s going in Monday.

My last conversation with Rob @ LL, was that their RGB integration module takes the color commands that would go to an LED, and process it and then send out the command to the lights connected to their box.

So with the ITC controller posted above, say zone-4 is the underwater lights. Those 4 circuits (B+, R-, B- and G-) would go to the LL controller, get interpreted, then sent to the LL underwater lights.

Thats how it was explained to me.

This supports that the ITC controller is master and LL controller is slave?

If ITC doesn’t work, then LL won’t work.

The good news is the ITC controller, if bad, is super easy to swap out.
