on the OLD solenoid (The one on the car)  I got 2.0 ohm on the lowest setting.

 

The NEW solenoid didnt register at all from Little terminal to case. However it was not installed at the time.  Not sure if that makes any difference.

Installation makes no difference, if   it is actually case grounded.  Only one small terminal?

 

What is your smallest ohm range on your meter?

I found this on the internet.

If you take a meter reading set to ohms on the lowest setting one lead on 3 the other on 1 disconnect the battery feed for the sol and battery on the starter relay and press your start button you should get a reading. If it is OL then the contacts are open and no current will flow. You are looking for the lowest number .03 would be great.

Next, take a reading on your starter sol between your wire from the Starter relay and a good ground or the body of the starter. you should get a reading. If you get OL there is a break in the wire or a bad ground.

 

NOTE this diagram is a - ground battery. just ignore this or switch the symbols if yours is a + ground

Bit of a thought last night.  What would happen if ONE of the brush leads in the starter was contacting the side of the starter?

 

It seems to me (An electronicnition with literal seconds of experience) that the lead would ground out stopping the motor from turning.  With enough voltage pushing through the other brushes could overcome the drop caused by the short and turn the starter.

 

Does that sound remotely possible?

Might be better if you had a known good spare or borrow that you could temporarily swap out to try it out.  Getting into it might cause more problems if you're not use to working on these.

Whelp.  I feel stupid.  

 

Starting to remove the starter to check the brush leads.  When I pulled the battery cable off the starter terminal it was bolted to came loose.

 

I thought to my self "Thats odd".  and started to tighten it down. While I am tightening it down I was wondering how much of an effect that could have on the starting cycle. Got it tightened down, replaced the leads to the starter and battery.  Sat in the cab and hit the key.

 

Turned right over. 

 

Thank you all for your suggestions advice and support. Turns out that it wouldnt start cause I'm an idiot.

I was just getting ready to bite the bullet and buy another engine until I adjusted the valves yesterday for the third time.  Turned out to not be a bad bearing!  We all have been there!  Best to own it and just laugh!  Glad to hear it is fixed!

I was a service engineer for 40 years in the commercial printing trade. I learned to check all the basic stuff first. It just might save you a huge amount of grief. Glade your up and running!

There were also times when I have taken something apart and after struggling to get it all back together I have said, "I wish I had never taken that apart" or " I didn't need to do that"!

 

I was once building on a 25' Trickle Impregnator or the Electric Motor Manufacturing Industry. Upon attempting to lever a rail with a large soft mallet I missed the bar and hit my forehead. I started to laugh because if I had seen someone else do it I would have laughed. When the other guy I was working with returned, he saw this huge bump on my forehead and said, "What did you do"? When I explained he had a good laugh.

 

We are all learning and all make silly mistakes. It helps to laugh at ourselves as we make those mistakes. I have often heard myself saying to myself, "Stupid boy"!

Reminds me of the time I was working on a creeper under a car at Dad's shop after working all night at my 'day' job.  Woke up with a sharp pain and large knot on my forehead.  Courtesy of the 1/2" drive ratchet and socket I had been holding over my head when I went to sleep!

So. I drove her to the "Corner store",  About 4.4 miles.  Put some gas in her.  Aaaaaand the starter was dragging... Got a jump from a guy in a big diesel 4x4.  Drove home and sure enough, the SAME terminal is loose.  Tighten it up and she turns right over.

 

 

I KNOW I tightened it down sufficiently.  I considered Thread locking the bolt but I am unsure what that would do to conductivity. my Buddy suggested putting a lock washer under the terminal.

 

I figured I would run the issue passed the experts.

 

What do you guys think?  Thread lock, a lock washer or some other sorcery?

Its probably no coincidence that it has loosened again, the post probably has another nut (and insulating washers/bushes) on the other side of the main casing which probably needs tightening  or needs a lock washer as well.

It might be possible that the threads are worn. You might try a known good one (new) and also use a lock washer
