Wild Generator Oil Pressure

[freewill2008]

Hi Gus -

The oil pressure guage is surely electric. The genset engine
controls would also be electric and possibly electronic.

Now, you also mention the battery is low or dead. Your electric
guages and engine controls will certainly be erratic if the voltage
is wrong.

Try charging (and doing whatever is needed to KEEP a charge) and then
see how everything works.

Best of luck.
