Well you pointed out a valuable point, that if the starter brushes aren't
making good contact, the pull in winding on the solenoid wont be grounded
and it wont engage, but if this is the case the lights wont dim in the dash
because no current will be drawn, or little current.  I could see and feel
mine drawing what I felt was enough to engage something anyway but I didn't
even get a click from it.   The braid often rots away too and causes the
same symptoms.

I don't know what causes them to stick, but they really aren't serviceable.
Whenever Ive taken them off they seem nice and free, but when they get good
and hot or cold they seem to bind.  This one had delayed engagement for the
past few thousand miles at all temps, but since it got good and stuck hot,
its been fine since.

I don't know why I queried your diagnosis, Keith, knowing that you're an ace
electronics guy!   Still, it might have helped someone else on here I guess.

Is it just mechanical wear in the linkage that makes them sticky, or a bad
copper contact pad maybe?   Adjustment possible?

Yes, that's true.  I had this motor apart when I did the resto and it was in
great shape, even after 150K+mi, so I doubt the last 10 have caused
problems.  IT DOES draw current, which means that the motor brushes are
making contact and the braid is intact, the lights dim pretty good when I
hit start so Im pretty sure its sticking.

This car has a '72 ignition switch on it, with 250K+mi, they are pretty
bulletproof and still available for replacement so I haven't used the relay.

Ive beefed up the electricals in this car a bit too... :-)

Don't forget the starter motor is part of the pre-engaged circuit - maybe
you've got the usual brush hang-up or whatever it is that we all seem to get
at some point.

Alternatively add a hard-start relay in the solenoid circuit?  That saves
your ignition switch too.

Anybody have any sourcing suggestions for a Bosch solenoid?  I got back from
a trip to PA Sunday and after a long heat soak it wouldn't engage, no way no
how.  It did start when cooled down but its been 'delaying' its engagement
for a while now.

Looking thru my stash they are all labeled "sticks when cold"
"sticks when hot"
"engages slowly"
"sticks engaged"

Etc. etc.  

Any good sources for NEW Bosch units?  Looks like im all out of good used
ones.

Thanks,

Keith
