PIPER CHEROKEE SIX / LANCE SERVICE MANUAL
NOTE: In the past, aluminum cable was used in wiring the battery circuit, battery to ground,
battery to master relay, master relay to starter solenoid, starter solenoid to starter, and
engine return ground wire to airframe. See schematics for your airplane.
If, during inspection, a fault in the aluminum cable is found, Piper considers it mandatory
that the complete cable assembly be replaced with copper wire and suitable terminals.
