My Pramac S5000 runs fine but is not ramping up on its own in response to load.
My Pramac S5000 runs fine but is not producing voltage unless I manually idle it up. Also, the GFCI 110v outlet does not work at all, the other 110v outlet works when the set is idled up. Also, in the past when you plug something in, the generator automatically runs faster to compensate for the load, as stated earlier I am having to manually speed up the engine to produce power.
I spoke to an EE at work today that repairs these generators and he thinks it may be a bad/weak capacitor. He may have one I can try to verify the problem befor ordering. I will update when I have more info. Oh - the GFCI not resetting may have been due to no voltage present (according to an instrument tech at work), so I will try running the generator manually at a decent voltage and see if the GFCI resets at that time.I spoke to an EE at work today that repairs these generators and he thinks it may be a bad/weak capacitor.

Just got the test caacitor from my co worker. Will report back after trying out tonight.Just got the test caacitor from my co worker. Will report back after trying out tonight.
Not the capacitor. Swapped them out with the same results. What could be causing the engine to run slow and not respond to load?Not the capacitor. Swapped them out with the same results. What could be causing the engine to run slow and not respond to load?

get the service manual from them no way to fix a hacked 6000w generator. engine RPM and HZ correct and voltage taps. wired wrong is huge danger to all. for sure grounds connected wrong./ or 250vac to any 120vac load devices.
Based on the information provided, it seems that the generator is producing voltage but not delivering it to the connected devices. Here are a few troubleshooting steps you can try:
Check the circuit breakers: Make sure the circuit breakers on the generator are not tripped. If they are, reset them and try again.
Check the connections: Ensure that all the connections between the generator and the devices you are trying to power are secure and not loose.
Check the voltage regulator: The voltage regulator controls the output voltage of the generator. If it is faulty, it may not be allowing voltage to pass through to the connected devices. You may need to have it tested or replaced.
Check the automatic voltage regulator (AVR): If your generator has an AVR, it may be malfunctioning and preventing power from reaching the connected devices.
Check the capacitor: While a visual inspection may not always be enough to detect a faulty capacitor, it is worth checking it with a capacitor tester to make sure it is functioning properly.
Check the wiring: Inspect the wiring for any signs of damage, such as frayed or broken wires. If you find any, you will need to repair or replace the affected wires.
If none of these steps resolve the issue, you may need to consult with a qualified technician to diagnose and fix the problem.
It could be several things but it sounds like it just running too slow. I would the engine rpms first. Depending if is a two pole or four pole and if your 60hz or 50 Hz on the needed unloaded rpms.
Example: 2 pole 60 hz. Engine needs to be running at 3600 rpm loaded and 3750 rpm unloaded; unless, it has a fuel saving mode.
A 4 pole 60 hz would running half this rpm. The 2 pole producing 50hz would have the engine running at 3000 rpm loaded (about 3100 rpm unloaded)
Now in order for the 50 hz system to produce the same output voltage it requires a different alternator than the 60 hz version; otherwords, You simply can't convert a 60 hz to 50 hz version without changing the alternator by changing the engine speed.
The first thing I would look for would be internal fuses blown. This sounds like a 460 volt 12,000 watt industrial generator and you probably should call the installing contractor for service. My 15,000 watt generator is over 30 years old and has less than 700 hours on it and those are mostly test-run hours.
inside the gen head in the back their will be a 1x1x3/8" black
with 4 wire conn thing it is a rectifiertheirs a hole in the center for mounting as well replace that and should be ok a big surge and age will take them out try this i willing to bet that's it unless it is smoked the part is common and avail by ebay as well as radio shack numbers will cross ref on the item good luck hope this helps
The volt meter indicates voltage when I idle the engine up.
