For awhile the parallel application worked fine. Now, even without any load, the red overload indicator will appear on one of the connected generators, and it will shut down its AC output (but engine continues to run). Then, on a restart it may happen with the other generator. No set pattern. Suggestions? Thanks
SPARKY, Looks like a poor connection somewhere in the jumper wires or terminals. When they are running OK under a load, try wiggling/bending the jumper wires along their length and at the connection to their terminals.
