Why, in all of Bob Nuckol s wiring diagrams, is there a starter contactor

switching the heavy current to the starter?  There is already a contactor
in the solenoid.  What am I missing here?

Al, Note that the current to the HOLDING COIL OF THE SOLENOID is through a hard wired circuit. The
inrush current of 35 amps is taken through the starter contactor, which on the secondary circuit
can easily manage the 35 amp inrush while the SWITCH be it a turn-key or pushbutton can easily
handle the 3 amps to energize the contactor.  Pardon me if this was already explained. Bill Jepson
