Thank you Jraef for the two speed motor diagrams.
If OP does have a 2 speed motor and connects like he mentioned - input to 1,2,3 and thought he was connecting in a wye and joined 4,5,6, he would drastically changing the phasing of each coil with these improper connections. May or may not draw high input current, but current won't flow through the motor as was intended, and looks like you would have some coils working against others basically trying to turn the rotor in opposite direction at same time, that would heat up windings. Similar can happen with typical 9 or 12 lead motor if you get all the right pairs for coils but happen to connect one of them with reverse polarity from where it should be.
