GT6 ignition light mystery

[lincolnsix]

My ignition light does not illuminate when I turn on the ignition,  however when I use the car and stop, 

 

turn off and then turn on again the light comes on. The light never shows while the engines running.

 

The alternator is charging fine,  I have cleaned the alternator contacts and tried a new bulb,  it seems 

 

as if something is temperature related.

 

Any ideas?    Thanks           John.

Unable to check the wiring diagram right now but if the bulb does not light you could have uncontrolled charging the wl monitors the cut in charge speed / voltage

 

ie a bigger bulb early cut in smaller bulb makes it later , good if you have wrong pulley sizes

 

doesnt help your problem.

if you disconnect and feed the wl lead from a battery the thing should light

 

sounds more like bulb holder and its earths is part to blame

 

or the regulator is failing

If I disconnect  the brown/yellow wire and earth it,  the light comes on with the ignition on.

 

Could this be a regulator fault?         Thanks Pete,        John
