No problem, I hold several mechanics licences, its just that I am a military mechanic, no dimmer switch in a tank (well yeah there is but not the same)
Unless I owned it I probably never worked on it...
That is why I am asking, I understand too much, got no book, and never worked on it...
I am thinking of the master light switch, and checking it with a meter, other than that and some other visuals I am almost done, without a having a book.
thanks
