Audio and Cigar Lighter

General Description

The circuit consists of the starter switch, radio, cigar
lighter and the relay.
The audio circuit is designed for the current to flow
through the receiver circuit when the radio switch is
turned on with the starter switch in “ACC” or “ON”. Cur-
rent runs through the memory circuit of the audio regard-
less of the position of the starter switch.
When the cigar lighter is pushed in with the starter
switch at either “ACC” or “ON” position, a circuit is
formed in the cigar lighter case to heat the lighter coil.
The cigar lighter is spring back to its original position af-
ter the lighter coil is heated.
