Wendell,

There is = some=20 benefit to using a starter relay in addition to the starter = solenoid. =20 The argument is that this arrangement will keep the fat wire going = to the=20 starter from being always hot. Also, I’ve heard stories = of starter=20 solenoids sticking with no way to stop the starter until it runs the = battery=20 dead. Not sure I buy that argument though. I tied my = alternator=20 B+ wire to the battery terminal on the solenoid (mounted on = firewall) rather=20 than running it all the way back to the battery (in the tail). = I also=20 picked up on the same B+ terminal to provide power to the Main Power = Buss. This saved about 25’ of heavy gauge wire, = offsetting the weight=20 of the solenoid.

Wendell, I would say that is = still a=20 standard for aircraft - for some on the reasons already = mentioned. =20 With a relay(Contactor) you can break the circuit to the starter = should it=20 stick or short.
