I have just bought a recon wiper motor and wheel boxes, from Robsport, for my '81 TR7 DHC as the old motor was so slow and unreliable. Fitting the unit was a bit fiddly but relatively straight forward. However, when testing the unit I found that the motor started but would not stop until I switched off the ignition!!!
I have removed the motor again and found that the black supply wire was abraded, leading me to think that it was shorting out; I duly repaired the abrasion and now find that whilst I have 'normal' speed and 'high' speed on the wheel box drive shafts, the da****d thing still
