Update
Got my MMM last week. Installed it and race this last weekend with everything running great. Convienced the MMM is a keeper I decided to pop the lid and make some of the mods mentioned in these forums. I unplugged the fan and ran the wiring directly to my receiver's ch3. I made the lid's opening a little bigger for the wires and that's about it. I plugged everything in and I get nothing from the MMM;ie no arming. I raced it last weekend and it did fine. I switched out receivers and do difference. Thinking maybe the switch went bad, I cut it off and soldered the two wires together and still nothing. I checked the batteries (the RX and the main) both are charged. Steering servo and fan works fine just no arming of the MMM. I've disabled the BEC and using power from 2S RX lipo (was doing that before with the MMM and it ran fine). When connected to Castle Link, the software still sees the MMM and can write to it. Any ideas?
-----------------------------------------------
UPDATE: I was just about ready to box up the MMM and send to Castle then decided I'd try one more thing. I ran the 3-wire cable from the MMM directly to ch2 of the receiver and it armed and worked fine. Prior to this I was connecting this cable to ch2 via an extension with the middle (red) wire cut. This was because I did not want to use the onboard BEC and was using a 2S 950 Lipo and a voltage regulator to power the receiver. This/that setup worked great as I went through 4-5 battery packs over the last week prior to the MMM dying. The MMM will now only run with the 3-wire cable directly connected to ch2 (with red wire intact) AND with the 2S 950 Lipo/volt regulator connected to the Batt input of the receiver. When I throw the switch on the voltage regulator the MMM arms completely even with the switch on the MMM being OFF. Even though the ESC arms completely it of course will not respond to throttle until I throw the switch on the ESC. Can someone explain what happened between my first set up (explained in 1st post) and the new set up that I must use now to get proper response out of my MMM?
