Seems far more likely that there is no power getting as far as the neon. Have you checked the switch? Start at the basics first! Neons can fail of course but it seems highly unlikely it would fail at the same time as everything else....it is after all only an indicator and wouldn't stop the generator from working even if it did fail.

Most neons dim down over the years mainly because they turn black but they rarely just stop working unless they get broken.

No AC getting to the rectifier and the neon not lighting suggests a fault either just after the switch, the switch itself or possibly a mains filter coil if there is one fitted. There really can't be much left to check.
