62 Dash lights

[bandmgrinding@xxxxxxxx]

Hi John,
    Thanks for the info. You don't happen to know what the output of the
" black box " should be and how it varies the dash lights? Is it the
cycles per second or the output voltage that changes. The shop manual
just says 200 volts and 250 cps in the radio diagram, nothing about what
controls it.
  Thanks
