923 will not stay runnig...?

[MAGNUM]

I'm looking at a 923. It starts with jump but dies when cable is unhooked. The voltage meter, in the dash, shows it is charging. Would completley dead batteries do this? I always thought the batteries just started the motor then the alternater took over.? Any ideas?

If its a 923 or 923a1 I believe there needs to be some battery voltage to keep the fuel solenoid engaged. I believe if you cage the fuel solenoid it will stay running. Does it have hawkers or the 6tmf batteries?

Four tan colered batteries. I didnt see any marks.?

Your Fuel Solenoid Shut off valve needs power to operate correctly. If your batteries are shot then it's a no go. When you're in a bind you can turn the knob on the shutoff valve to over ride the electronics (opens the fuel valve manually). However, you'll need to use the Emergency Shutoff handle in the cab to shut her down. Be sure to reset the shut off valve lever on the unit if you do use the Emergency Shut off handle.

And, you will most likely burn out your voltage regulator!

So four new bayyeries sounds like the answer. Are they 6 volt? Thanks.

They are 12 volt.
