It seems to be battery related. If I pulled the battery back a little bit it would work intermittently. I ended up shimming up the contacts on the driver and it seems to be working better.It seems to be battery related. If I pulled the battery back a little bit it would work intermittently.

Depends on how fast you're seeing. Cheap LED power supplies are what we call, "half wave". This means that they only work on half the AC cycle, and do blink 25 or 30 times per second (depending on where you are). If that's what you're seeing, it would be normal.
If they're blinking at some other rate, do you have them on a dimmer? Some dimmers don't get along well with LED power supplies, and blink at 1 to 10 per second.
Giving 2 short beaps and 2 red leds on it blinked .
If its a EY7440 ? the control pcb must be the problem itself , but if its a brushless model then the 6 mosfets on the motor could be short circuit EY754* was oft the cause, but they have modified the motor for the new EY75** models with brushless motors .
