I've recently bought the 8015 two-outlet smoke pump from Tower Hobbies. I've just hooked it up and plugged it in for the first time, and it appears to failed right out of the box.
2S LiFe battery freshly charged, brand new tubing, and only removed the inlet/outlet protectors moments before hookup, so contamination is unlikely.
Pump started out at high rate, then quickly slowed down and stopped at full setting on transmitter (30 seconds). Now will not turn at all. Is this thing toast? What steps can I take to investigate?
