Good morning!!!!

The big news here is Walmart opened this morning at 9:00. It closed thursday afternoon. We have a lot to be thankful for. Here we all have homes to come home to, even if the power is off. Saw a video from southwest Va and they showed a twig that with the ice was 1 1/2" to 2" thick. We didn't have anything like that.

Ron, don't do the falling thing, it hurts. Prayers sent.

Buppies, Prayers for the shoulder.

Welcome new guys.

Prayers sent. Ed

"Ron, don't do the falling thing, it hurts."

Nope Ed. Falling doesn't hurt. It's that sudden stop, by the ground, ..... that hurts!

Good morning. I'm up early and ready for a good breakfast, in preparation for a hard day of physical activity ahead.
More firewood collecting, chainsawing, post digging ? Nope, something far more tiring - the grandkids are coming :laughing:

David, not much experience with faulty generators so sorry I can't be sure what that is. This would be my first guess from looking at the picture on the scope.

[1] Red arrow. The little discontinuity at each positive and negative zero crossover is typical of a circuit with rectification (guessing diodes in the excitation winding) . Although the voltage waveform is at zero at crossover point, current will still be flowing through a diode and it doesn't "want" to stop immediately. Eventually though the current does stop quite abruptly, so the magnetic field producing the voltage waveform dips, hence the little blips. This suggest both that the diodes are working and that if it uses only a single excitation winding, it has not gone open circuit.


[2] Purple arrow. Voltage has stopped increasing sinusoidally, magnetic field must not be increasing as normal. The field is made up of two parts and much of it is produced by the excitation winding, so very likely not enough current flowing in this winding. But you have already tried another AVR and it doesn't look like the winding is open circuit. Is there a capacitor associated with the excitation winding that is not in the avr circuit you swapped out ? They often have one in series with one, or sometimes two, excitation windings. Alternatively, shorted turns in the winding would lead to early saturation of the magnetic field and give that flat top to the sinusoid - but if that was the problem, I can't think why it would build up in that non linear manner.

Thanks Eric,
Going to pass this along to my resident experts. I guess main questions becomes is it fixable and if not can i continue to use to power my chargers without damage.

I can tell you why I fell in a 3 page essay. :confused3: But best I can say is be careful. :thumbsup:

Ron, I hope you're alright as can be. I watched a lot of news videos of cars sliding, people slipping, and wreck after wreck the last couple of days. Seems this storm caught many offguard.


I need to go get diesel. I saw it in Bastrop Texas for $2.79/gallon. Many places it is still over $3/gallon. My buddy and I have noticed that this year, diesel is staying about $.70 - .90 cents a gallon higher than regular gas. It used to fluctuate lower, and higher than regular, but the last 10 years or so, it seemed to be maybe $.35 per gallon more. I told him I wish I had a gasoline powered tractor too.

So my daughter's 8th grade science class had a "balloon powered car" competition. All of the materials for building it were her idea. She wanted foam for the body, picked some 5 mm x 220mm wooden dowels, and last but not least, she chose mason jar lids for wheels. Not the whole lid, but the 2 part ring and lid type where we just used the lid part. Walmart had them in the 2.75" diameter size. So she told me to saw the basic shape of the car foam body on the bandsaw. Now comes the advantage part of having a machinist for a dad. I took the lids and dowels to work and drilled a hole for the axle "push pins" to fit through. I had just the right sized drill, and used my 6 jaw chuck on the lathe to grasp the lids and drill the hole very close to true center. I then drilled some undersized holes in the ends of the wooden dowels, so that the push pins would be a light press fit. Also put the car's foam body in the mill to drill the axle through holes as true as possible. She painted the body and I showed her how to assemble the wheels and pins for the least amount of friction. I also had a 6" piece of 10mm diameter nylon tubing that I heated and bent a curl on one end. We used some orings to connect the balloons. She told me the teacher says they could use 2 balloons. Since we only had 1 tube, I said we would put 1 balloon inside the other for more flow. After some different tube configuration testing we settled on the best and then took the car apart for transport to school. She put her car on a shelf in the science class when she got to school, and some boy stole her wheels and axles when she was in another class. It was found out that he took them, and she was able to get them back and complete her first day's competition. I went up to the school and complained that the kid should be in some form of trouble or another, and they said they would handle it. But my daughter doesn't believe they did anything to the punk. Anyway, she won the first days initial competition, and then the 2nd day's she said she won by even larger margins. So she ended up winning the fastest, the furthest, and the best looking by the class's vote.

I'm planning on teaching her to drive my 4310 tractor today, so she can help me mow. She's very mature, will stay clear of obstacles, and has been driving the riding mower for 2 years now.

RNG, I'm guessing there will be a shortage of N95 masks, so use them until you can't stand them before you throw them away. So sad about all the deceased and missing. What a horrible catastrophe. I remember the Japanese sent over balloons, hoping to start such fires. I'm still so glad you took so many precautions with fire prepping your land/home. Maybe a good reason to build a pool and have an automated fire suppression sprinkler system around the home. Sadly, not much left to burn. And we were worried about dam's breaking and earthquakes prior to this.....

Don, the war on weeds is a difficult situation that has manifested itself to GMO herbicide resistant varieties. I was told early on that roundup was in the chemical family Getting more and more bushels per acre has driven the ag industry to these extremes. There are no easy answers for this. And hay farmers put all kinds of chemicals on their fields to kill weeds too. Which ends up in meat, and Drew's garden. But some of the weeds have toxicities and need to be curtailed from getting harvested with the crop, so what do you do? Then, top it all off with the use of pesticides and we really have some bad stuff going in our bodies. I eat Oat cereal daily, and don't buy any special stuff, so who knows what will happen...

Have a blessed day all.

Thanks, Drew, but not quite accurate. I have no clue how to run nor read the oscilloscope. Hoping I can find people that do, like Eric

We bought a big sack of Thanksgiving groceries for a church wide effort to provide 50 families meals on Thursday. Our church bought the actual turkeys and got everything to the food bank yesterday.

Hopefully someone will have a better Thanksgiving day because of it.

With Thanksgiving and Christmas coming up, we have a chance to be selfish and create big smiles for ourselves by helping some folks, that for whatever reason, can稚 help themselves. If it痴 dropping off a turkey or a bag of potatoes at the shelter, or making sure some kid that thinks Christmas is just for other kids, finds out Santa loves him too, or slipping $5 to a homeless guy that might buy a burger, or might by a bottle of wine. Either way, if do what we feel is right, what others do is out of our control.
We get the feel good and someone gets helped. We are all so fortunate while many are not. :thumbsup:

Amen, Brother...

Hey Guys, just a reminder but falling is NOT good for us guys. Let’s be careful out there. And be thankful we still recover - eventually.

Welcome Paul
Like Drew said, we like pictures

Drew, have you looked into some sort of solar for the barn? Maybe not enough to actually heat, just keep above freezing? Even if just a portion you keep the freezables.

46° here this morning with forecast high of 73°. This is our "normal" range for this time of year.

Still have one section of driveway, near the house, to regrade but should finish that today.

Sorry to hear about your fall Ron.

Everyone please ..... have a great day!

Prayers to all.

Looks really good.
If you desire more practice I have a few hundred feet in need. Not high enough on priority list to get my attention in near future ☹️
