Topic: balancing volumes on an HSH Ibanez/Strat own-build guitar.

Hi, I`ve just finished building an HSH Ibanez bodied( and neck), guitar, with coil-splits on both humbuckers, and a strat 5 way switch( the coil splits are by mini-toggles).
Everything seems to be wired up OK, as all 5 positions are working, as are the coil-splits ( checked by tapping pick-ups with screwdriver in all combinations).
The problem is with positions 2 and 4, both with and without coil-splits - they are very quiet compared to any other position( with and without coil-splits).The middle single coil is well balanced with the 2 humbuckers on its own, but something is dropping the volume down considerably when its combined with either the neck or bridge humbucker.(The guitar has 1 vol, and 1 tone pot, wired conventionally - 250k pots).
I`ve tried different pick-ups in the middle position, with different polarity, but the problem persists.
Anybody got any ideas as to what`s happening here?Any advice would be most gratefully received - thanks.

make sure the middle pick up is not being connected in series with the 2 other pick ups
when switched in
can you post a schematic

I thought this was normal.  Certainly my SSS Strat and HSS Aria suffer a volume drop in positions 2 & 4.
