Hi everybody. Thanks for taking the time to help. I have an M929 with Cummins NCH-259 engine. I have had no start, and no crank for some time. I haven't had a lot of time to mess around with it, after I killed a set of batteries while switched off. I now have 24 volts, and 10 amps going to the starter constantly with the switch turned off. When I try to start, I only get a quiet click from the electrical box behind the washer fluid reservoir. No action, or sound from the starter. Is there a relay in that box that is the problem? Do I need to replace the entire box?

You might try opening the start box on the firewall. It may be corroded and has taken a turn for the worse. There is a rebuild thread on how to replace the contents of the start box...

Smack the box with a hammer a couple times and try to start it.
Thanks Elk. I tried that back a few months ago. But it's worth trying again before taking the thing apart

Look for thread "Ever see inside the protective control box".

Took me a bit to get the right solinoids. I tried just replacing the starter solinoid, but that didn't work. Finally got the abs solinoids replaced today. Starter cranked! So happy to hear that sound again. After a couple of long cranks with no start, I went to the zero start. Got it to fire, but the rpms went crazy, nothing I did could bring them down. When I shut down, the temp gauge blasted out at me with a spark. Has anyone else ever experienced this? What did I do wrong?
