Someone built me a NG1000/P4 MagAA module using the mariposaoyako copper heatsink. It functions well in general, but causes some flickering especally with the bezel fully screwed down under certain conditions. The flickering eventually disappeared with the module properly (and firmly) clamped to the MagAA body.
However, after switching MagAA bodies a few times, the flickering came back, and eventually the module is dead. Even worse, although the LED won't light up, there is still electricity flow when powered up, but a measure of tailcap (battery) current yields dangerously high levels. With the module operating normally, tailcap current remains at around slightly above 1A. Now the current jumps up to a whopping 6.4x-7.xA. Running L91 batteries for ~10 seconds will render them very warm. And yet the P4 still wouldn't light up.
I hardwired the SSC P4 with a separate battery pack and the emitter lights up nicely. So the LED is not the problem, but something else. I suspect some form of short-circuiting inside the system, or the driver board simply got fried or whatever.
Can someone tell me what's going on? I intend to have someone open op the module and check. What steps should be taken? Please advise.
