WouterVessies Posted October 9, 2020 Posted October 9, 2020 Is it possible to power a power functions IR receiver with an 9v LEGO train speed regulator or an other non-LEGO 9v power supply, instead of a power functions battery box? I tried the 9v train speed regulator, it doesn't work, but the power function lights and motors are running well on it. Quote
1963maniac Posted October 9, 2020 Posted October 9, 2020 SavaTheAggie's response may help you. I have seen someone on Youtube use the battery box for this. Sariel has good info too. Quote
dr_spock Posted October 10, 2020 Posted October 10, 2020 The 9V train speed regulator would output to the C1/C2 pins on the PF connector. The IR Receiver needs power on the +9V and ground pins of the PF connector to work. The PF LEDs and motors are powered by the C1/C2 pins that's why they work with the train controller. Quote
WouterVessies Posted October 13, 2020 Author Posted October 13, 2020 Thanks for the information. I added a battery box as shown in the first Youtube movie and this works. Quote
