Installing a voltage regulator in a 218 series movement


Voltage regulator components
These are the main parts that need to be identified for the installation of the voltage regulator.  Clockwise from top, left: Coil Lead-Strap Screw, insulation (supplied with regulator), and the voltage regulator.
Starting point for installation
When installing the coils and tuning fork, be sure the cell coil lead-strap is under the component coil lead-strap.
Installing the insulator
Using one pair of tweezers, lift the component coil lead-strap so the insulator can be inserted in the fork of the cell coil lead-strap.  Be gentle so as not to over stress the lead-straps.
Placing the regulator in position
Lifting the component coil lead-strap again, place the regulator between the lead-straps and over the insulator.
Install screw
Using the tweezers to hold the screw in position at the insulator, screw it into place and...
Final placement of regulator
...move the regulator to with 0.5mm of the cup of the tuning fork before tightening fully.  Be careful not to tighten any more than needed to be secure and make good electrical contact.  Test by verifying that continuity exists between the lead-straps in one direction only.
