murrayec Posted June 6, 2022 Share Posted June 6, 2022 Installing LED strip DC coach lights in Cravens;- The coach body is held on by the floor side dents which slot into the glazing- 4 to each side, use cocktail sticks to disengage the dents and the body lifts off. The bogies pop off by rotating them 90 deg and levering one end up. Setting up the electrical pickup boards which are epoxied to the underside of the bogies, the jig is for soldering the .3mm NS wire to the boards. Holes are drilled in the bogies, the chassis and the floor between the toilets for the wiring. Bogies wired up. Chassis wired up. The wires run along the side of the weight. Floor on and the wiring threaded up through the hole in the floor at the toilets. Wires from the bogies have a generous loop to allow the bogie free rotation, before running up through the chassis. The electronics- stay alive capacitor, a resistor to bring down the LED strip brightness a bit, and a rectifier for polarity control. Electronics assembled. The tops of the coach dividers are trimmed a bit to allow for the LED strip to pass through. LED strip installed. The LED strip has a mini connector to the electronics so that the body can be disconnected. Testing. With lights installed one needs a few passengers!

Nice to see anti-flicker capacitor installed. Make a big difference when they are running. On some I've put a micro pot in so lighting level can be adjusted. 1 1 Quote Link to comment Share on other sites More sharing options...

Billycan Posted June 7, 2022 Share Posted June 7, 2022 Agreed a to-do project. Lighting makes a huge difference. Three dedicated drills so no changing of bits as you go. Nice idea Eoin. 1 Quote Link to comment Share on other sites More sharing options...
