Title says it all. Our 'farm' truck has decided for a second time to not crank. Last time I charged the battery and it didn't help. Then a random try to start it and its been working for weeks. Then yesterday no crank.

Anyone have the diagrams with the ignition switch and relays and whatnot?

My brothers yukon has a random no start issue. Pretty sure it was the crummy side post battery terminals and probably not so good of grounds on the body/egine/frame. After cleaning the scuzzy terminals the prob was lessened. Not sure if he ever went at the grounds because it worked most of the time.

I think I figured out its a weak starter.

I used the "trouble finding pokey screw driver with a lightbulb and a lead thingy" to verify that starter was seeing voltage at both big post during starting.

Then I hit it with a hammer and it started.

Incorrect.  That's what it USED to be called.  From this point forward it is now called the trouble finding pokey screwdriver with a lightbulb and lead thingy.

To wrap this up. I crawled under the vehicle, then decided I needed it up on jack stands. Pulled the battery to charge it since I was cranking it so much, then got the truck up in the air. Pulled the two long starter bolts and the bolt that holds a plastic shroud around it. Then had to figure out how to get it out and get the wires disconnected. Ultimately pulling the passenger wheel and inner wheel well gave me enough room to get some socket extension in there to get the wires off. Once the big cable was off of the stud, the starter can almost fall out. 

The cross member below the starter ate multiple dropped tools. I found them but swears were had.

Installation was the reverse. Got the truck out and the daily driver back in the heated spot. Life is good.

I have found having Cleetus Mcfarland on makes wrenching much more enjoyable. #hellyeahbrother
