hi,my backpack is dead,when i hold my finger on the power switch the red light flashes quick and stops flashing once i remove my finger,the battery is fully charged-any suggestions-thanks

If your battery is good, then open up the backpack (2 screws) bypass the circuit board and if the pump operates with no problems, then your circuit board is at fault, if the pump fails to operate then its your pump at fault.

Before doing the above, I would make 100% sure its not my battery at fault.

cheeers jeff,do you know if batteries are easily damaged when dropped

[jeff1]

You can break the cells inside a battery by dropping it, only one cell has to be damaged and the whole battery becomes naff.

Check that you got it connected !

Not being funny, when I first had mine, I was trying to switch the thing on without the pole being connected - just to see if it worked - then had a strop when it didn't !

Aparently it needs backpressure from being connecte to something to work !
