Electrical problem: no crank

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...

Thank you Chucky. I'll see if I can find that thread. I'll crack that box open and see what's going on in there too. It might be into next week before I get to it
