Generac Generator

[roachcoach]

Installed a new starter in my generator and started up right away the first 2 tries then started to drag and click . I checked with a generator repair shop and was told to check my voltage at the batteries while cranking and to check my grounds. Is there anything else I should do?
Ok I tried starting up my generator with the engine running and it started right up. Not sure what to make of this but my mechanic is coming by tomorrow.

It does sound like low voltage to the battery that the generator is connected to. While the engine is running then the alternator is putting out 13.5 volts (or more) and that will allow it to start quickly. It will be a expensive mechanic call to have them tell you the same thing, if nothing is wrong with the battery. Yet if you have a defective battery, the mechanic might be able to tell.
