Oh my. I cracked open my Regulator because it suddenly stopped working the other day, and came across this hot hot mess.

As I surmised, there's a pesky optical sensor behind the flywheel cage, just above the clip. You've also got a controller board, a thermistor board, and various leads going to the rev trigger and LEDs. Yikes.

This is the first blaster I've encountered that uses a rev trigger sensor rather than a good old-fashioned flywheel motor switch. The rev trigger sensor activates a circuit on the controller that turns on the flywheels. I'm sure it has something to do with the logistics associated with the burst fire mode, and keeping the flywheels going even when you let go of the rev trigger. Thanks Hasbro.

The dart trigger is also a different kind of bird. It is partly mechanical, and partly electrical. The trigger pulls back on a rod that activates a switch buried under the controller board which starts the conveyor. Simple. Um, right ?

I've been able to determine that the thermistor is cutting out as soon as batteries are inserted. It gets hot. So hot, I can hardly touch it. Sorry about the camera angle, but it's located just to the left of the battery box on the upper half of the shell. (The red, gray, and black wires go from the thermistor board to the controller board)

So the question I'm faced with now is, what's causing this, and what to do about it. And that my friends, due to my BAC, will remain a mystery for another night.
