Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, my name is ***** ***** I am going to assist you with this.
What is the actual model number of the unit, from the data label?
Those are the numbers of the engine itself.
I need the model number of the genset.
Yes, that is the number I need.
Make up 2 jumper wires that will attach to the brushes, with a 5A fuse in one of the jumpers.Connect the fused jumper to the positive (outer) brush and to the positive terminal of a 12V battery.Connect the other jumper to the negative (inner) brush, but do not connect it to the battery at this time.Gain access to the exciter wires.Start the set, and connect the negative jumper to the negative terminal of the battery.Set your meter to VAC and measure the AC output at the receptacle of the set.
How much voltage do you get?
Sorry, I forgot to take that part out. Just ignore the exciter wire.
No, a genset puts out AC voltage. You need to set the meter to VAC.
Is there any chance you can get a couple of good, clear pictures and post them here?
I would like to see inside the end cover of the alternator, as well as a couple good shots of the back of the control panel, so I can see how the receptacles are wired.
Everything appears to be right, so due to the fact that the genset will not produce power on its own, but does produce power when you jump 12V to the brushes, it means your voltage regulator is bad.
