All solenoid/starter combination is lever/linkage design. The only way the starter to energize is by solenoid’s contacts. Also solenoid pulls the lever to slide the bendix drive into ring gear. You will never have close circuit until the bendix drive is fully engaged. In other words, no starter will spin or cranking until first bendix drive is engaged before the solenoid’s contact is closed to energize starter motor.

Read the “Electric starter”

Read the paragraph “A freewheel assembly……” under “Uses” subject.

Attachment of the cross-section of a Delco solenoid/lever with motor.

On following your suggestions and muddleing with this as best I can, I could not find a problem. I pulled the starter and took it to the local shop for further testing. 
 They hooked up power to the starter and on the first test it made a "clunk" sound and did notheing! This is the second time I have found "the" problem.
 A complete rebuild is $260, I told them to go ahead and do It, I can pick it up tomorrow, if the shop is still there after Fay goes through Grin   Will keep you posted.  Jim

Sounds like a solenoid failure.   GM style solenoids get old and that's how they act.  Often hitting the button repeatedly will result in starting. 
There a big plated washer on the end of the solenoid plunger that closes the battery main to the starter motor when it pulls all the way in.  If the washer/contactor is burnt, it'll pull in but the motor may not turn, or the starter may not turn at starting speed. 
On the brighter side, if you keep "finding" the "problem", you're gonna get it fixed sooner or later...if it takes every dollar you got!  Wink
Good luck, JR

I am @$# u me ing  that becuse the starter is attempting to start, ie the bendix is wrinnnninnnnn spinning. That the fuel pressure switch is good Huh
Mean bad bendix drive.

They hooked up power to the starter and on the first test it made a "clunk" sound and did notheing! This is the second time I have found "the" problem.
 
Mean solenoid's relay contact is worn out to a point partial or no contact.

Usually if one thing is worn out mean the rest of the starter/solenoid needs to be completely rebuild.

This is off topic, but, ...

ROAD SIDE FIX...

Turn the washer in the solenoid around... it will give you a clean slate to start from.

I have indeed had the situation on my 4104 where low voltage would allow the starter to spin but not fast enough to engage the Bendix.

I just had my starter gone through, bad solenoid, $119 total price. Could have happened because of low voltage, as my batts were in sad shape. Got the starter repaired, new batts and she fired right up! That is the second time I have done this in 5 years. Them suckers are HEAVY! I need to invest in a battery minder, or whatever you call it.  Grin

Hope yours is fixed and ready to make that diesel rumble.

Jim,

It isn't clear, was the solenoid still on the starter when it was tested? If so the problem still could be the solenoid.

Paul,

I solved the heavy battery problem by going to two Group 31s to replace the monster 8Ds. I only used two but three will easily fit into the one 8D space. I live in a mild climate so I only need two. Cold climates probably call for three or four G31s. This also gave me space for more house batteries, a very nice setup.

Well, at least you will have an overhauled starter (Maybe?) that you won't have to worry about for a while!!

Gus,

That is exactly what I did several years ago, replace two dead and tired 8D's with two group 31's. Much easier to handle too!

Paul
