Green is Onan. Yellow is Powertech. Now for to state you have only seen it once. How long have you owned the RV? Do you not check the fluid levels in the Onan????????? Doug

You need to post which Genset you have. Do you have the Powertech? If so, Powertech sells a plug in charge module to keep the chassis batteries charged and supplies the necessary 12 volts to keep the Genset running, when on Genset. If you do NOT have this module on a Newmar Powertech genset and you run the Genset for more than 6 hours, the chassis batteries will be depleted and go dead and when that happens the genset stops.

1. 2000 DSDP, will NOT always keep the chassis batteries fully charged while plugged in. The DSDP uses an Intellitec bi charge relay system to engage BOTH battery banks to charge from the Converter OR Inverter/Charger which ever you have. The Converter was standard and the Inverter/Charger was an option back then. The problem with the Bi directional charge system is simple, the Charger MUST be OVER 13.2 volts for the system to charge the chassis batteries. BUT, once the charge voltage goes to float, that charge voltage drops below 13.1 and the chassis doe not stay in the loop.
2. 2000 DSDP has a small solar charger above the drivers seat with a charge LED indicator on the dash by the radio. THAT small solar charger is installed to overcome the very small parasitic 12 volt draws caused by the Diesel chassis 12 volt controls. Odds are THAT solar charger is NOT working due to the age of your unit.
3. The Genset (Either ONAN or Powertech) do NOT have a battery charger. They also start from the chassis battery bank on your DSDP
4. YOU DO NOT HAVE A FULLY CHARGED BATTERY/S ON THE CHASSIS BANK.
5. You need to connect a small 10 to 20 amp battery charger to the chassis battery bank and charge for 24 to 48 hours to get those batteries back up to full charge. Doing what you did only put a small surface charge on the chassis bank and they will go dead in a few days.
6. The reason the Genset cut off when you released the button was because the Gensets do NOT produce any 12 volt power and NEED the power from a 12 volt source to stay running. Doug
It is NOT unusual for the chassis engine to NOT start from the Battery Boost switch. The POWER it takes coupled with DEAD batteries(the batteries pull some of the needed current) means that the starter will not engage. What you need to do, is, use a toothpick to keep the Battery Boost switch engaged and then let the Shore Power or Genset run for 30 to 60 minutes to get a surface charge on the Chassis battery bank, then the engine will start.

What type of batteries do you have ? Wet cell or AGM or ???
And when you put in the new ones did you "manually" charge them fully first ??
First check that the batteries are really charging when you think they are. Most configurations charge BOTH sets when the engine is on but only the house batteries when on gen or shore power.
You may have a situation where you need to physically disconnect a main cable at both battery sets when not in use. This is often MUCH easier than trying to trace down parasitic draws when you think everything is OFF.
It takes WAY longer than an hour to recharge the batteries if they are substantially discharged.
