1995 S6 starting issue
 

1995 S6 manual
Having trouble identifying starting problem
Turn key, lights come on, then a click, then occasionally starter spins once and starts
Repeat, sometimes it takes two times, sometimes twenty
Took out starter, tested it, it is ok. Cleaned contacts, and tightened ground wire.
Still doing it.
I have heard it is the ignition switch, so, open to ideas.
Is there a separate part of the switch that's easily replaced, and does anyone have info/diagramhow to do it?
Could it be the ignition module? Where is that located?
Thanks,
Bruce
