Looking at the pic, I don't think that's the same starter I have.
I'll snap some pics tomorrow, I'd do it now but I'm experiencing a nasty thunderstorm here in Cajun country.

 

My solenoid is on the starter, I wonder if 2005 was the last year they put them on the firewall.

 

Solenoid is on the starter. Starter relay is on the firewall. My 07 had the starter relay still on the firewall. If you jump it and engine starts, bad relay.

 

No start from a jump, tried that early on yesterday.

 

You jumped the starter relay using a screwdriver across the two big posts? Not talking about jumping the batteries. If so, still sounds like a bad ground.

 

Maybe I mean relay instead of solenoid...I do remember it was on the firewall. I'm not very mechanical. I just know we thought our starter was bad and it ended up being a $30 part changed in less than 30 minutes.

 

Sounds like a bad bendix to me. Idk about on the new 39mt but on a 42 that's 50 bucks. The 39s are much lighter but every one i know that turns wrenches says they don't hold up. I'd put a 42 back on it.

 

A relay looks like a fuse with prongs. The thing on the firewall with two finger sized cables going to it is a solenoid. It also will have a small ground wire or ground direct to the body.

 

You either have a 39 identical to the one Oscar posted or a 42. The input 2 starters i habe ever seen on a large diesel engine and I've worked on almost every common diesel from the early 60s 238 Detroit's to this series 60 in my 03. Cat cummins detroit... All the same starters, just different nose cones.

 

Anyone at the yard?
