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 registering, even with a load. The low electrical output indication appears correct as the output will barely start a portable fan.
Sometimes (more often than not), the HZ meter will reverse (peg far left) and the volts will simultaneously move to the green and the % power indicates correctly. At this time, the unit has enough power to run a chop saw .... % power initially jumps to 110%+ on start-up of the saw but drops to sub 50% once the saw is running. Again, appears to be operating correctly at this point with the exception of the HZ meter pegged low. Any suggestions?
