I am having electrical issues in my touring car, I need some ideas or direction on solving them. This is what I have and some ideas. The speed control just stops working and does not transmit any power to anything. Turning on and off doesn't work, once the power is gone it doesn't come back. All electronics are less than a year old.

Possible issues discussed so far....
-X-12 motor has seen temps around 220
-X-12 motor has had soldiering iron press on tabs for too long
-X-12 motor may have has a small drop of soldier run down the wire tab. (no obvious signs though)
-Bad speed control (multiple tried and all failed)
-Possible issue with servo

-Team Associated TC6
-LRP SXX Stock Spec (new version)
-Futaba BLS551 servo
-Spektrum SR3100 receiver
-LRP X-12 17.5 stock spec
-DX3R Remote
-AMB transponder
-Much more high speed fan

Please help
