Instrumentation - Current Generator not Generating Voltage

Not enough voltage for the x-ray machine to image properly or none at all? After e-testing the gen output, then you might bench test the generator, and then under load equal to the x-ray voltage reqmnt.

I would assume that this is a generator with a voltage regulator. If it is open the output breaker, remove a cover and expose the output breaker, put a digital multimeter, preferably with frequency function, phase to phase at the top of the breaker, start the genset and run it up to rated speed, check the output, the rule of thumb is 10% output without the regulator operating, its usually closer to 5%, if you see a voltage output in this range with the proper frequency, you have a defective voltage regulator. Try this and get back to us so we can see where to go from here, also if the frequency is low bring the engine up to rated speed, most quality regulators have under frequency protection

Is there some reason why the original equipment manufacturer can't help over the telephone?
