Depending on the storage location mice can wreak havoc.
You might have to re flash the field...

Field flashing is used when the exciter poles of generator lose their
magnetism and will not allow gen set to build voltage.. This sometimes
happens if a machine has not been run for long periods of time. To
rectify this problem we use a 12vdc battery to repolarize the exciter
poles by applying voltage to the exciter circuit directly. The gen-set
must be offline and proper polarity must be observed.. The gen-set or
voltage regulator manufacturer usually has procedure for this in manual..
