Is a enduromaxvx7000i generator non sinusoidal?

generator set will occasionally encounter generator failure in the process of use thatCummins generator setis not generating electricity. What is the cause of it? And what to do about it? In fact, there are a lot of reasons that Cummins generator set is not generating electricity. The following is compiled by Jiangsu Starlight Electricity Equipment Co.,Ltd to summarize the main reasons for generator not to generate electricity and the treatment methods.

what car? and year>? and country , so we can look it up in our
great online sources. (all 3 must be known)
in the USA we use alldata.com (or the dealer FSM)

i guess you dont know that some heads are not torqued, or use TTY bolts, right? some are set by ANGLE degree.
that is covered in the FSM all that. the facts.
most head failures result from guessing.
or asking here, with no facts on car.
some engine run different heads, and different if turbo.

case in point, all this Mitsubishi engines

• 8 4D56
  • 8.1 Non-Turbo
  • 8.2 Non-intercooled Turbo
  • 8.3 Non-intercooled Turbo (TD04 Turbo)
  • 8.4 Intercooled Turbo (TD04 water-cooled Turbo)
  • 8.5 Intercooled Turbo (1st Generation DI-D)
  • 8.6 Intercooled Turbo (2nd Generation DI-D)
  • 8.7 Intercooled Turbo (3rd Generation DI-D with variable geometry turbo)
  which one?

my guess
Mitsubishi Triton

Not sure where you got 9.63 V from but if think about it - you are measuring about half the value then what you are putting in, so if you are putting in about 14 V you will get about 7 V half rectified (half as many sine peaks). There is nothing wrong with your multimeter and oscilloscope would be better for measurement than DMM.

use premium non-ethanol fuel(shell,BPS etc).Many stations to the west & north (,Hustisford & many other town's PREMIUM are non-ethanol) and add some sea foam to it. that ethanol is junk. If not used in 30 days toss it. nothin' but trouble.

Make sure your generator is outputing the correct voltage and frequency. There should be NO reason this will not operate off a generator of the correct voltage and frequency. You say it "will not run"... exactly what does it do? Some generators may cause noise in audio equipment... Also what brand generator and power handling are you using? Some generators use an invertor at the output and those MIGHT not like the starting surge of this speaker. With two of these you will probably want a 2KW generator. These likely will NOT run from an invertor unless it has at least a 1 KW rating and is sinusoidal.

Many of the MTH Protosounds 1 and 2 and Trainmaster will not work with the Lionel CW-80 electronic power source. The output waveform is so non-like sinusoidal. The electronic sound systems will not usually respond to this waveform and when they do, the sound will be garbled. Use another power source.

The CW-80 is not suited for electronic sound systems. The output is non-sinusoidal. When electronic sounds are generated for some locos, the sound will be garbled. Use another power source. The Z1000 MTH power source or similar is recommended as are many other older Lionel standard power xfmrs. For the sound stay on problem with switch off, try putting a fixed load on the tracks ie: An accessory of some kind (lights etc). Usually a fixed electrical load will fix this problem. Overall, I would recommend changing out the power source and save yourself a lot of headache..

Check and replace the brushes, this a 95% fix on most protable generators.

Speed, unless VERY low will not cause your problem.

You likely have a failure in the generator section.

You need to determine if the unit is a permanent magnet rotor or a brushless type. IF it is a brushlesss type with rotating diodes on the rotor, it is likely one of the diodes has shorted. Also the capacitor across the regulating winding may have gone bad. either shorted or open.

You need to check the voltage.you are getting out. Unfortunately, mist meters will not read correctely unless the wave is sinusoidal and if a diode is out, the waveform will not be.

If the unit is a permanent magnet type, you may have a shorted field winding.

Your generator may be putting out a square wave instead of a true sinusoidal (sine) wave.

There is usually a circuit in the microwave which monitors the AC line for timing purposes, and a square wave may not be interpreted correctly.

I would consult the manual or contact the manufacturer or installer.
