Ive received you email and picture.

Calum

Your motors dont appear to have a built in earth to the chassis.
You simply want TWO seperate speed controllers or one DUAL controller.

Ive added you on Messenger should you wish to chat.

the speed controller ive been testing the robot out on is a dual one, which because of the motors using an earth( 4 volts--- which i tested using a multimetre) it only allows one motor to operate at a time,

i think if i was to get 2 seperate speed controllers like woody mentioned above i think that should work because they would be both using an earth but they would be on a seperate circuit does that seem like it would work???

but if not ill have to make the motor brackets out of poly

The motors have two wires and I can see no reason for the scooter motors having an extra internal connection to their casing.
Did the donor scooter have an earth wire from the battery to the chassis?
If not Id suggest that the motor armatures have a fault ... did the windings look a little cooked in the motor you took apart?

hi, there wasnt an earthwire from the battery to the chassis, and as for the motors windings i think they were fine i cant remember anything looking damaged ,ill have to have another look.

it works!!!!!!!!!! ive wired it all up again and for some reason it now works with the dual speed controller that i have, but i need to get a better one as it is ment for combat robots up to 6 kg.

calum, sounds like you had a loose wire or somthing shorting on the chassis.. go through all your wires and connectos etc and check for no stray cables or scratched wire insulation..
