Grahamgl Posted November 8, 2014 Share Posted November 8, 2014 Can anyone advise me what the sweep angle is on the DR3A wiper system on the GT6 please? Also, I have downloaded a wiring diagram for a GT6 and it shows a Blue/Light Green wire going from the switch to the wiper motor.what is the purpose of this wire please?I am trying to find a DR3A wiper motor that is suitable to fit to my TR4A, after mine packed up on the RBRR causing a forced retirement, and the one off the GT6, DR3A No.75607B, seems that it might be suitable. The 4A DR3A has a sweep angle of 120 degrees.ThanksGraham Quote Link to comment Share on other sites More sharing options...
Rallyspit Posted November 9, 2014 Share Posted November 9, 2014 The TR4,5 & 6 and GT6 mk 1 & 2 (and Spitfires 1,2,& 3) share the same windscreen so I would assume that the wiper sweep would be the same. Quote Link to comment Share on other sites More sharing options...
