Starter Problems

[k20]

Hey guys, working on my m1008 and am trying to get it to start. It still has the military 24v starter on it, I have the batteries in and wired for 24v. Batteries are in good shape. When I try to start it, the starter engages the flexplate, and it will turn over, approximately 6 or 7 teeth, and then it will stop and sit there making a buzz/click sound. Let off the key (ok ok, screwdriver) and let it 'reset' and it will turn over the 6 or 7 teeth again before it stops.

When it is turning over it is very slow. I checked the voltage at the junction block on the firewall it was 23.76v and at the starter I had 23.74v. When I turn the key to start that voltage drops to <1v. Is this the starter, wires, or starter switch gone bad? Thanks guys.

Not sure about 24v stuff but a 12v system will usually show 13 to 14v, so I assume a good 24v system would show more???
Check all the earth connections and the wiring. The motor is ok is it? Not hydraulic'd?
Maybe try a booster battery as well to eliminate the possability of your batteries being bad?

Well got it turning over, replaced all the cables and she spins like a top

I'm wondering why these guys that convert to 12v don't run a series switch to keep the starter 24v... Much better in a diesel app...
