Hi, Mark....unfortunately, I am presently working
as a heavy truck mechanic (18 wheelers), and I have been on many a road call
where the starter was stuck engaged.On a few units, once I disconnected the
batteries (4 of them) the starter would be OK to use again. On two of
the trucks, I could not get to them in time, and it burned the wiring harness so
badly that the whole harness had to be replaced. The other tractor burned
to the ground. Melted all the tires, all windows gone, all fiberglass hood and
fender parts melted....not a pretty picture.
I have a quick
disconnect on the negative terminal on my motor home so that if the starter
solenoid should hang up, I can simply open the blade-style switch and disconnect
the battery. Hopefully I will never need it, but it's nice to know it's there
just in case. I have been looking at the various battery switches/quick
disconnects at West Marine, and have been considering one for my aircraft.
Heck, it's convenient jus to be able to quick-disconnect the battery when
working on the panel, fuel pumps, spark plugs/wires, etc. Just a
thought. Paul Conner

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?
