dude its fixed the bigest trouble is bin seeing it , there aint nothing wrong with the motors ive since found out, just a dump valve sticking open so when it pumped it just dumped,
it seams the switch for front pair sometimes sticks to dump, then when useing independent switch didnt pump no where so nothing moved.
its me being thick

ill be back in themorning , hope ya coming back
dont forget the woofie
cheers mate
