Vertex 7500 not generate energy - Coleman Powermate Powermate 5000W Generator

Have you let it set for a long period? I have heard that if you do not use a generator that it will simply stop working(generator portion itself). Make sure no breakers are tripped and the wiring looks OK.

Hi!

It might be the Magnetism in the alternator has dropped out if it was stored for a long time.

We suggest you "Flash" your alternator. Follow the steps below:

1. To re-excite your alternator, we suggest you only use this method, as described by our friend DonyBoy7 on YouTube: https://www.youtube.com/watch?v=lsN9S1luQzA
2. Run the generator for 20 minutes without load to stabilize the magnetic field in the Alternator.
3. Test with a suitable appliance to make sure the load is stable. If not change your AVR/Capacitor. (Depends on what is fitted to your generator. 2-4 wires = capacitor. 5+ wires = AVR)
4. If burns out replacement use our tests to determine the fault: http://www.generatorguru.com/help-me-fix-my-generator-repair-advice/.

If results are below 1 Vac, repeat step 1. If this continues please contact us.
If results are between 1-7 Vac, but you are not getting full voltage at the sockets, then you will need to replace your AVR/Capacitor.
If results are above 8-10 Vac range, then you will need to replace your AVR/Capacitor. But be warned that the high reading will damage the AVR/Capacitor over time. This could result in it lasting a fraction of the time expected on a stable alternator.
If results are above 10 Vac range, be sure you removed the AVR/Capacitor before testing. If you have and are receiving this result, we suggest you take your generator to a "Motor Rewind" company for repair. You can find your local Motor Rewinding company by doing a search on the internet for "Motor Rewind." It is worth asking for a quote from a few Motor Rewind companies as their prices can vary greatly.

Next try to decide why it is failing to prevent the next one from burning out:

1) You overloaded the Alternator Output - Please be aware unless you own a Honda, Pramac, SDMO, Suzuki, Yanmar or Kawasaki, who stated the running watts on the generator along with the max watts, then you might have only been told the max the generator can give out. If there is only one rating on the Generator this is a good indication of showing the Maximum Watts only. In this case please try to run the generator at 3/4 the max power. This allows for surges when you start equipment and prevents the Alternator and AVR from being overloaded/blowing.

i.e. 6000 watts on a Chinese Generator = 4500 running watts with a max surge to 6000w for a short time while the equipment starts.

If you run over the 3/4 you will continuously blow AVR/Capacitors (depending on what is fitted to your generator) and could end up blowing your equipment and the generator alternator. This could create a fire in the alternator and, as it is under the fuel tank, can be very dangerous indeed!!!
Please also be aware this wattage is split between the 2 lowest voltage sockets (windings) i.e. in our example the 4500 running watts would be 2250running watts per plug. You also CANNOT use the 230/240v socket at the same time as any of the 110/115v/120v sockets, as this winding is used to make the higher voltage. This is the case on all generators!!

2) What you are plugging in has an electrical fault. - Try another piece of equipment. If the AVR/Capacitor keeps blowing, run the test in this video to determine if there is a fault in the alternator. https://www.youtube.com/watch?v=tC_LrrZcx38&lc=Ugw379k2UvCOdfICcM14AaABAg

3) AVR was faulty - If alternator test gives good results, replace the AVR.

Hope this helps!
