Guest Posted June 20, 2004 Report Share Posted June 20, 2004 The heater fan on my '69 six isn't working. there's power to the switch, which is working.there's a green/brown and green/yellow going into the heater box together with an all white wire. I can't find the white wire on any wiring diagram I have...whats it for? where does the earth for the fan motor attach to the car? could it be a bad earth? Any help/ideas greatly appreciated as I don't want to take all the dash out. Cheers chris Quote Link to post Share on other sites
Guest harry dent Posted June 20, 2004 Report Share Posted June 20, 2004 The white wire connects to earth.Triumph in their wisdom connected a white from the motor then black to earth. Regards Harry TR5 nutter Quote Link to post Share on other sites
wheeler Posted June 20, 2004 Report Share Posted June 20, 2004 Chris Have a look at this web site http://members.aol.com/danmas6/ it's actually an advert for Dan Masters TR Electrics book but does give a very good description of the heater motor control circuit as a sample. Hope this helps. Best regards Bill Quote Link to post Share on other sites
Guest Posted June 21, 2004 Report Share Posted June 21, 2004 Thanks both. Harry, are you sure the white is earth...I took off the nearside hose, looked up into the fan housing and the white APPEARED to be soldered to the same terminal as one of the other wires (green/brown, green/yellow...can't remember which) Thats why I dismissed it as being something else. It does, however look like an original joint. Cheers Chris Quote Link to post Share on other sites
Guest harry dent Posted June 21, 2004 Report Share Posted June 21, 2004 That's the one. Regards Harry TR5 nutter Quote Link to post Share on other sites
Guest Posted June 21, 2004 Report Share Posted June 21, 2004 harry, so, IS the white on the same terminal or have I not seen correctly. If it's on the same terminal it will take the power coming from the switch straight to ground surely! Quote Link to post Share on other sites

Guest harry dent Posted June 23, 2004 Report Share Posted June 23, 2004 Chris I have the motor in my hands.Green and brown goes to one side of the ballast resistor,green and yellow to the other side or resistor,with the yellow/green looped into push on spade terminal on the motor.Black (in my case but white on my TR5 motor)spade terminal on the other side of the motor which is the earth lead.If you are still confused I will take a digital photo and send it to you.harrydenttr5@aol.com regards Harry Quote Link to post Share on other sites
Guest ron Posted June 23, 2004 Report Share Posted June 23, 2004 My TR6 ['75] had the same colour coding and fixture as Harry said, and the earth wire was black. if I remember right the earth was quite a long wire with a 1/4" ring on the end. I wonder if some previous owner has replaced the earth with a white wire?? Ron Quote Link to post Share on other sites
