screen pump connections

[simonfraser]

bought this on line, which connection is +ve ?



going to solder some tails on and seal them with glue and heatshrink - easier to do in the workshop than hanging upside down and testing which way round to connect the motor ...

tnx

Simon

ah, answering my own Q

 

[Refueler]

Often in RC - we used Car Screen pumps to refuel the model aircraft ... a simple 3 position switch that decided which way to pump .. fill model or transfer from shop container to flight container.
But last pumps I bought - it made no difference which way I connected - the pump delivered same direction regardless !
