Well gentlemen, I am back. Been away for a few years. Everything has been working on my generator relatively well. Recap. I have a mep004 that I converted to 240/120 and eliminated the VRM and replaced with a SX-460. At the time I also added a relay so that when in "start" it would use the...

I love all the input on the governor. I will ditch the idea. As for the solar charger, I would love to but my yard is filled with big oaks so no sun hits the ground. I will check the alternator wires. I checked the fuse a while back. Thanks all!

"since the original system is pretty good" Does the utility have a mechanical governor? I though that was only the precision units. Maybe the precision has a better governor. It was my understanding that the utility model was a fixed throttle set by me at startup.

So I haven't put a meter on everything but the charge meter is always showing negative when the genset is running. Does that mean it's drawing more than charging? I would assume that it's not charging at all and using the battery a bit. i don't remember the amps in the negative. The...

Today was wiring and test day. I wired the genset to the house with 6 guage wire into a 60 amp breaker. I know it's not a transfer switch but I'm not ready to spend that kind of money yet. I switched off the main breaker of my house and on the 60 to the genset. I kicked the gen on and double...

So I finally had some time and ambition to work on the genset again. I ordered a new sx460 since I fried the other one. I ordered a nice 24v 10a DPDT relay. Took 24v off the SRS switch in the start position to trigger the relay. So the sx460 is hooked up to the 120vac and the relay. The...

OK so j13(L) was just a made up example BUT page 4 of what? I have 4 PDFs and the first several pages are always a bunch of repeat junk :)

I'll try to decipher if I can use that to do what I need. I have a really hard time figuring out the wiring based on the manuals. I only have 20 minutes here and there to look at it so I don't get to trace the wires manually. I have an electonics background and can read a schematic no...

Right after I got the sx460 I removed the stock AVR. Unscrewed 2 plugs and physically removed it from the genset. Wired the sx460 streight to the field and 220v. When I cranked the genset it runs great. No output. When I measure the output at the 220v its 1.5vac so not enough to get the new...

I finally started doing some educated guessing. I just cant find the information I need. I have now blown up my sx460. Not that it's the end of the world but I am frustrated. I tried wiring it in with a diode in place but wasnt sure how I should connect it. I ended up just using a full wave...

Thanks! I may just give it a try. The AVR was $25. Right now the genset is an expensive boat anchor making my front yard look redneck. If I fry the avr then I'll just grab a new one. I know which pins on the old avr control the functions but I don't know if I can simply unsolder the old...

So you gave me enough to move forward. The S9 (speed switch) controls all the timing and connections during startup. The main thing that frustrates me is that there is nothing I have found that tells me where the wires go then they leave the AVR. When I added the new AVR, I wired it...

As I understand it, most household generators start producing because there is enough residual magnatism to create a small voltage that the AVR uses to power itself and "builds" the voltage from. I know these have a field flash built into the AVR which makes sense because you don't want to be...

So AVR is in and works wonderful... as long as I manually flash the field. I plugged a corded drill in the convenience plug and gave it a little spin and everything comes to life. I was able to set the voltage and steady everything out. Works great until I shut it down. When I start it back...

Tonight was fun. I finally got to convert to single phase. Mine was a tiny bit different than the youtube video. My copper bar was on the bottom of the board and had all the wires over it. Made it interesting to cut. I used a dremel and cut it in place and then removed one nut to remove it...

So now that I know the genset works, I think I will convert it to single phase and replace the AVR with a sx-460. I wasn't overly happy with the stability to the voltage when running and I think I would be better off with newer technology. I understand I wasted $40 getting the old AVR...

When I said it took 9 days to ship it, I meant it took them 9 days to put it in the mail and 10 more days to get to me. I am working on getting my $4 (woohoo) back from them. I don't care about the $4 I just want them to pay. I got the new part today from the US vendor and soldered it in. IT...

I have not been in the military. It was more that I looked for a US based company because I didn't want to wait. Everything on their site was US including their address. After I ordered it took them 9 days to even ship the item and it was shipped from China. When I asked them about it they...

I found this to be very enlightening. I was struggling to figure out how the AVR controlled the large current load. I understood how it was modifying the voltage. http://portable.generatorguide.net/avr.html

So been a while. I ordered all new semiconductors for the VR. At least the ones I couldn't test with a good level of certainty in-circuit. Well 19 days later they showed up from China (long story - wasn't supposed to be from China). There is a DC voltage regulator on the board that as soon...
