My truck did this after a hard landing, wreck, etc. when the steering servo would draw a lot of amps trying to keep things in line (drawing more amps than the BEC can hope to supply). You don't happen to use a Savox servo, do you?
KO servo.
We looked for LED flashing and couldn't see any, although it is possible.
Thanks for the ideas, I'm not sure what to do with it now though, as its a perfectly good speedo, but l one out of warranty and I don't know where to get it repaired.
