2000 613 starts fine when warm,cold mornings it turns over decent. But no smoke put the charger on it an it will light right off.  When you turn key on it goes through all the motions (anti-lock ) turn on to start turns over when you let off the key it goes through the motions again that isn’t right.  So is there a selinoid week or is the batteries that close to not holding voltage up?

Does it go through the motions again when you let off the key with the charger on it? Could be a battery issue, a starter solenoid, or ignition switch. I would look at those closely first.

If your batteries get too low the ECM may go quiet. Not sure what the threshold voltage is, but I recall Cummins use to be high, like 10 volts or lower is a no go.

I don’t think it goes through all the clicking again with the charger but it will always start then. Cant hear anything!   I noticed when I put the charger on it says 10 volts so I’m betting there isn’t near 12 volts to the ecm.  Started good yesterday at 50 degrees out.

I would remove the battery terminals from all 3 batteries and check each one individually one by one with a volt meter. There may be weak or dead cells in them. I would get them tested at your local auto parts store if you cant test yourself, this would be the least expensive diagnostic step to take imo.
