Hi! Hoping someone can help- my stArship trooper is blowing fuse f21. I’m pretty sure it is a problem with the auto launcher. If the auto launch is disconnected, the fuse doesn’t blow. If it is connected, it engages as soon as the machine is turned on and pop goes the fuse instantly. I’ve replaced the diode and I’ve replaced the transistor. I’m at a loss for the next step. Any ideas or suggestions?
