the 'ambient' lighting over the kitchen area in my swift challenger 480 How do I get at it to repair it? I changed the tube, with difficulty! but still not working so how do I replace the unit?
The tube should not be difficult to remove. From the working position, it should be turned 90 degrees, so that you can see the pins at the ends, then pull out. Reverse when fitting the new tube, and you should feel the pins clip into place
If it still doesn't work, test the spade connectors to the tube with a voltmeter which should show 12-13volts.
If you have power then its the unit;no power troubleshoot the wiring
