[Mgs] Ignition light always on, low glow

[Hans Duinhoven]

My 71 GT had the same and besides the brushes and the diode pack, the rings 
had to be replaced, whereto the brushes are making contact to.
Bit more work - I had it done by a specialist - I needed more tools than you 
recommended.

Cheers,

Hans
