Typical amp draw for old Onan 2500 when starting?

My Onan has a hard time electric crank starting. I can start it by hand though without to much trouble. Would anyone know. ball park figure,  how many amps needed to crank the Gen. over?

I was running the gen. today and watching the 12 volt output. Which was typicaly 14.8 volts. Occasionally dropping to 14.3. I gather there's no built in regulator on these units? I assume I will need to add a regulator asap to protect the starter/ house batteries.

I would say the same amount of amps for an automobile.  it's happened that I had managed to draw my house batteries too low to crank mine over and had to use the ASSIST button on my dash to kick in the Chassis battery to start it.

Sorry, was not able to find the cranking amp specs anywhere.

The charging voltage is not regulated

Thanks guys. I'll have to post a pic and serial number etc. Just refreshing my memory on voltage regulators now.
