Wendell,
There is some benefit to using a starter relay
in addition to the starter solenoid. The argument is that this
arrangement will keep the fat wire going to the starter from being always
hot. Also, I’ve heard stories of starter solenoids sticking with no
way to stop the starter until it runs the battery dead. Not sure I buy
that argument though. I tied my alternator B+ wire to the battery terminal
on the solenoid (mounted on firewall) rather than running it all the way back
to the battery (in the tail). I also 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 of the solenoid.

Refering to the battery going directly to
the starter, most all starters with built in solinoids are so
wired. I remember having a starter to hang on occasion and drain the
battery or ruin the starter. Is it practicle to use a relay in
conjunction with the starter/solenoid set up?
