On early (eg. 1963) Ramblers, the dash voltage regulator is a 19th century
style make/break thermostatic device. They fail, and are made of
Unobtainium. They can easily be replaced with a modern "three terminal"
regulator, ala LM7805 or equiv. I did this years ago. I recently had to take
out the dash gauge cluster for another reason so I too the opp. to
photograph it. To the right is how I mounted it under an existing screw,
also grounding the unit; to the left is a closeup. You can get 'em at Radio
Shack. You have to solder wires on it. Clip off the center pin. With the
mounting tab at the top, the left pin is "IN", connect to battery on gauge
PC board. The right pin is "OUT", 5 volts. Connect to regulator trace on
PCB. IMPORTANT: mount the tab onto a GROUNDED screw as I did (tab is GROUND,
same as middle pin cut off). Gently bend up pins and insulate/protect with
epoxy. This works well with almost any AMC.
