RE: splenoid=relay

[Ferdinando Di Matteo <aroctech@domain.elided>]

	The big difference is that Solenoids  handle large loads mechanically 
and electrically.  Relays as we know them in vehicles switch on 
relatively lighter loads but heavier than many  manual switches we find 
in our cars.  When you ask why the Spica coild start solenoid draws 
more current that the starter solenoid, the simple answer is size and 
mechanical load.  The starter solenoid has many more coil turns with 
larger wire to do the job of moving the Bendix drive as well as sending 
very heavy current to turn the motor.  The Spica cold start solenoid 
must push down a very strong spring where space is limited so without 
getting into how it's built, trust me it is strong enough for that job. 
 However. the load for the ignition switch is a bit much  to operate 
both especially withh a battery not fully charged or when it is cold, 
freezing, and motor oil turns to jello whiich loads the starter more 
then not enough juice from the battery which loses much due to the 
cold.  I could go on but you should get the points.   Mr. Elliott  too.
