"Ignition switches are junk"
Regularly hear this and similar consternation. I have continuously owned one or more 914s since 1998...think I have replaced only 1 ignition switches over that time, in one car. My current primary car I have had for over twenty years, still on the original switch as far as I know, I have not replaced it during my ownership. None my cars have ever had the added relay although I'm not against it. For those switches removed and in other key ignition switches I have opened up, what I see is part of the housing is cracked in similar locations. Maybe from years of torquing the key over? Not sure. I don't see melted housings (believe they are nylon), no smoke residue or anything out of line, just the cracked housing. Suspect the cracked housing causes some internal misalignment of the internal contacts...i.e. the switch goes bad and needs replacement. I am thinking the problem is the switch housings that break, not anything to do with excessive current flow through the switch. Educate me please. |
