HELP!!! DEX410 electrical problems

[dasbo]

Hi folks,

I am having a hell of a time with the electrics in my Durango at the moment. I have an intermittent fault which is causing me a lot of DNF results.

Basically, my car will cut out without warning and I will lose all power, even steering. On picking the car up, I notice that the speedo power light is on, but the receiver light is not. If left on, it will come back to life after anything from 20 seconds to 20 minutes. Its got so bad that I recently had to borrow another car to be able to compete at a local meeting.

Over the course of the last 3 months I have tried combinations of two 6.5 motors (one brand new), three speedos (Nosram Pearl ITSC - brand new, my spare LRP SPX super reverse and LRP SPX Stock Spec from my TC) and two receivers (Futaba 603FF and 603FS from my TC). I have also made sure the connectors which plug into the receiver are on properly, and that the motor sensor lead has been replaced. The only thing I havent changed is my Futaba 2.4Ghz transmitter and Demon lipos.

I thought I had it cracked after having more than a dozen 5 minute test runs last week (after installing my LRP Stoc Spec speedo from my TC) but unfortunately it happened again this weekend. My temperatures after a 5 minute run (checked everytime) are well within limits so it cant be a thermal shutdown. I am not a complete novice but this has got me stumped.

Has anyone got any ideas, as its getting to the stage where I'm seriously thinking of giving up offroad, even though I prefer it to TC, and love the car.
