I've been noticing some strange behaviour with my custom cliffjumper. He has 4 white LEDs in his chest, and one blue one in his eyes. The 4 white LEDs are all wired through one 100ohm resistor, the blue one is on its own resistor (I think its a 50 ohm). Power is supplied from a 3v battery pack, there are 5 other figures running of this pack with no issues. I turn the LEDs on but every now and then the 4 chest LEDs will flash intermittently/drop in brighness or go out altogether. The head LED always remains constant and has no problems. I removed all the wiring and resistors and redid it all, the problem is still there. There are no shorts or dodgy connections anywhere. The only thing I can think of is a dodgy LED in the chest, I will replace them tomorrow but I'm curious to know exactly whats happening here. Any ideas?? hakka.
