With the engine running (initial start) but prior to turning the power output on, the hertz meter on the 531a is pegged far right, no indication of load or volts on either 531a meter. On the mm, hertz or voltage are 0. When the electric power switch is turned on, the 531a’s hz meter is still...

I recently acquired a 531A and was able to get it running .... using the TM .... but have run into an issue I can’t find addressed in the TM. The engine appears to be running correctly but on initial start up, the Hertz meter is pegged to the far right and volts and % power are barely...
