another MMM problem thread!

[E-Revonut]

I know...another one! I'm clueless as to what happened here. Lately I've been having an issue with my rx losing its bind when the truck sits for a day. Truck ran fine last night, my first run on 6s. charged batteries up and brought to show my friend tonight, no communication between rx/tx, so I rebound it. I hit the throttle quick and it worked as did the steering servos. I then unhooked the battery to get ready to go outside, then said nope I don't want it losing its bind again so I hooked it back up quick and it still worked. I left it plugged in for about a minute just sitting there as I put the body back on and my shoes on. It gave a beep reminding me that it's all hooked up and not in use (annoying feature but I guess it's a good reminder) then went to drive it out the door and got nothing! Not a beep, stutter, or led! I gave up and came home. It still links with my castle link, yellow light comes on and it programs but when I hook up a battery no beeps or leds, and no power to anything! I hooked my MM up to my rx and that still works as do my servos. Is my MMM dead? I thought when they died they also wouldn't link with the castle link? I have already eliminated the switch but to confirm I pulled the case of the MMM and checked for continuity across the switch leads and thats all good. So now I'm asking you guys and Patrick. It sucks that I just got my 3s batteries and this happens!

Same thing happened to my MMM V2, except I was already driving for about 7 or 8 minutes when I lost power. BEC is dead...

[MetalMan]

Yep, BEC. I actually watched my V2's BEC die through its voltage fluctuations that my Nomadio React displayed through its telemetry.

im about to be REAL optimistic here... try shorting the switch.

removed the switch weeks ago, already used a voltmeter to check continuity across leads to rule that out

sadly mine is on the way back to its maker... i was late to work doing final tests to determine what it was. even a 7.4v lipo was too much for it. cut out and rolled to a halt... no more lights no more sound... heres to 4 weeks wait... at least :P
