Roel J Posted January 27, 2009 Share Posted January 27, 2009 Hi there, I have placed some Carling switches from Mudstuff to my Defender 90. I have the X-Eng fan controller unit and I have for this used a switch ON-OFF-ON. Funnily enough, only on the manual override, the tiny red light goes on, so in auto mode I have no visual indication that the auto-mode is on. Can anyone tell how to get the red light working also on the other ON? What have you guys done to get it working? Thanks!

Ex Member Posted January 27, 2009 Share Posted January 27, 2009 That depends on the switch. The switches are available with a large variation in the way they are wired. If yours does not have a separate light circuit, you are probably stuck with the way it is working now. If I understood what you did, you should be able to wire it in to allow the light to come on in both manual and auto. The "OFF" position should be manual off. How about you show us how you have wired it and supply information on the specific switch and we can help. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 27, 2009 Share Posted January 27, 2009 Just a thought... the 'auto' mode, the power feed to the switch, is it being switched by the fan switch before it reaches the Carling switch and therefore would only work once the fan switch kicks in? Again, without knowing how it's wired up it's difficult to diagnose the problem. Apologies if I am pointing out the obvious there....

Orange Posted January 27, 2009 Share Posted January 27, 2009 That's exactly what I was thinking Bowie!! The little red light should only glow when the fan is on, therefore if it's a diesel Defender and you leave the switch on auto, you'll hardly ever see the red light as the fan is seldom needed.

Roel J Posted January 28, 2009 Author Share Posted January 28, 2009 Well, thanks already for the answers! I shall try to draw a diagram over te next WE, 'cos a mate of mine is mainly working on the wiring... The note that the red light goes only on under full load is obvious, but will be tested! Keep you posted! Quote Link to comment Share on other sites More sharing options...
Ex Member Posted January 28, 2009 Share Posted January 28, 2009 As stated, the fan should not normally come on with driving on the road in a TDI, so if you are waiting to see the light, it will be quite a while. The only time my fan runs is off road in the summer. Quote Link to comment Share on other sites More sharing options...
Roel J Posted February 4, 2009 Author Share Posted February 4, 2009 This is the reply I got from Mud on my question regarding the switches: Hi This is something we noticed only recently ourselves. We contacted Carling and have been informed that is the correct way for the switches to work. Only one 'on' position will illuminate the warning light. Carling does not offer an alternative switch that will light the LED on both 'on' positions.
