Hello all. First time posting and impressed with the help on this forum.
Also I started a new topic, This one is so huge it's hard to find anything in the tons of knowledge listed. However I thought better put on here also as my other might get overlooked. new topic is also in test issues.
I'm trying to re-wire a HF generator to parallel. I have tried many things I found on this site as well as others and I just cant seem to get it to work. I have the wiring diagram but not sure how to get it on this forum. If anyone can help I can e-mail it to you.
What I have tried was to switch the wires as explained in the 3000W Chinese Gensets Info. topic on this site. I do that and I get 20 volts across the two outputs. I also read that if you get 0 to 50ish volts to switch a set of leads. I didn't try this and I'm not 100% clear on which two leads to switch??
To try and explain without the diagram, I have 4 wires coming out of gen head. Coil 1 has Red and White. Coil 2 has white and black. Red and black are power and whites are neutrals. Coil 2 is the only coil that the AVR monitors.
So at the terminal block, I take coil 1 red and coil 2 white and put them together, and coil 2 black and coil 1 white and put them together. When metering across the two I get 20 volts.
I have been testing at the terminal block figuring if I can get it to 120 volts there then I will worry about the rest of the plugs and things down stream.
Any help would be greatly appreciated.
Thanks all..
Does your 240V outlet have TWO wires on the Neutral connection?
If so, you should be able to isolate the two 120V windings that are in series for 240V. The Neutral connector is the "center tap" if you will. Breaking that connection separates the two 120V windings but keep in mind that to get both windings together you must observe that the windings are not reversed "phase".
Easiest way to determine proper phase would be the use of a O' scope so you can observe the waveforms.
The following website talks about a Coleman 120/240V gen being converted to 120V only and has some good diagrams and info on the conversion that you might find helpful.
