67 Dart Headlight Switch Demystified
Ok Steve stop crying. (This one had a broken wire in the rheostat and the sweep contact fell off while I was cleaning)
So I started cleaning my newly aquired parts. This 67 ish headlight switch looked good but the rheostat had really high resistance, in the megaohm range, I looked at it under magnification, and saw that the lead under the river was broken.
SOOOO, what to do, take it apart!
This is what it should look like
This is the front plastic spacer that also stops the knob from rotating too far
This part engages with the knob shaft and the rheostat.
Spring that puts pressure on the rheostat
Rehostat, the coil should be uniform, I tweeked it when I removed it, turns out it is imbedded in some plaster in 3 spots.
Contacts inside the switch
Sweep that makes the contacts and moves with the knob stem
Frame (nubs are where the ball bearing rides and creates the stops)
Rivets
