In the past my S3 has had a catastrophic wiring overheating and melting incident (not of my doing I hasten to add) which now needs sorting out (read rewire). As part of this I was intending to replace the ignition and associated mechanics with a push button start. However, I do not want a repeat of the melty thing so just wanted to clarify a few things before I get going.
Brown wire = direct feed from battery +ve
Brown/red = feed to glow plugs
White/red = feed to starter solenoid
White = Everything else (via fuses)
So, one switch to connect brown to brown/red and brown to white (or should that be two so that glow plugs are switched off independently) and push button for brown to white/red connection. Hey presto, flick switches to arm system and then push button to start . . . . . . .
Have I got it right, or should I get ready for more smoke and melted plastic?
Thank you for any help that will put my mind at rest.
