Bendix cruise control on mid 80s PT

[bluesteelll]

Does anyone know where the cruise control off/on switch picks up 12
volts dc? I read only 11.6 volts at the switch and the batteries are
on float at 13.6 or so. The cc worked when last I drove the coach, the
end of July, and wouldn't set at all yesterday.
