RE: What Did I Do to Break My Generators???

Wow. What a disaster!!! How could I have fixed so many small and large engines in my life, even done rebuilds and never run into this problem before?? I had absolutely no idea you had to keep a small engine level at all times even when it’s not running. 4 stroke Outboard engines all tell you how to move them and store them. Lawnmowers? They don’t necessarily stay upright as you put them into a pickup truck. I’ve moved these generators around on end many times. Just never stood them up for 20 minute like that before. I also didn’t know scratching off deposits on a modern plug could damage them. I can’t understand how I had these huge holes in my knowledge of engines. Especially after I’ve fixed dozens. What the heck? Guess there’s always something new to learn. The air filters were full of oil, so the carbs must have also been full of oil. Thank you for the posts. They have all been really helpful. I am doing a really big, full time project right now and didn’t feel like cleaning out the carbs because it’ll take too long. I’ve cleaned carbs countless times on these small engines and know how long that takes. So I’ll let the Northen Tools service department do that while they put in the new AVR which was all I was doing. Can’t believe swapping a pair of AVRs between 2 generators resulted in this because of the way I tipped them.

RE: What Did I Do to Break My Generators???

Have you topped off the oil since losing some into the cylinder? Jerry Yup. First thing I did. It wouldn’t start if it had low oil. It’s got one of those sensors.

RE: What Did I Do to Break My Generators???

Ok. I’ll replace the plugs. Also, I only rotated it about 15-20 degrees backward by hand to check what the issue was.

RE: What Did I Do to Break My Generators???

One problem remains. It now runs like ****. It’ll only run full choke and has good moments and sputtering moments. I ran it for about 40 mins now at no load and full choke. It just died after a sputtering, Smokey 40 minute run. It stopped smoking after 5 minutes or so. I also sanded away any fouling on the plug’s business end after the smoking stopped. It’s not running well at all. What’s next? New plug, even though it’s not too badly gunked up? Please tell me I don’t need to do a carb cleaning.

RE: What Did I Do to Break My Generators???

Pull out the spark plugs on both machines. You hydro-locked them with oil. Pull the recoil cord to get as much as possible out. Replace the plugs, start them up. Expect lots of smoke, as the oil burns off. Expect to replace the plugs with new ones, after the smoke quits. Also a genius. That’s exactly what it was. Burning off the oil right now.

RE: What Did I Do to Break My Generators???

Combustion chamber full of oil now? Pull a sparkplug and see if it will turn Solved!! You’re a genius. Got the oil out of the cylinder and trying to burn it off so the thing runs right again. It’s putting out a nice 120v when it’s not sputtering.

What Did I Do to Break My Generators???

I’m at a complete loss. I broke BOTH of my generators doing something very simple. I currently have 3 (qty) 2400 watt Nothstar Generators. They have always run like a Swiss watch for me over the years. I have owned 2 others before these over the decades. I currently need 3 because I’m off grid and have a living area and a workshop area to air condition. Meet the generators: Generator 1: bought 2 years ago. Ran for thousands of hours trouble free. Ran any time it was above 85F in Florida. Hard to even imagine how well this generator performed for a gasoline portable. Recently, the AVR (automatic voltage regulator) went bad delivering 90V instead of its normal 120. Generator 2: Bought 6 weeks ago. in the work area running like a Swiss watch. Generator 3: Bought 6 weeks ago. Carb started spraying fuel out the top after about 4 hours of use. What I did: I put generator 1 and generator 3 next to each other and set them on their ends so the power heads were sticking up in the air. Oil cane out the breather tubes. Whoops. I then took off the face plate from the generator heads, took out the AVRs and swapped them. Now neither generator will turn!!! I cannot pull the pull start. It’s jammed!! I can turn the generator in the opposite direction from normal rotation. I can even pull the pull start to turn it back to where it is jammed. But I can’t pass the jammed area in the rotation. My mind is BLOWN. I definitely caused this problem, but all I did was stand the generators on end and swap the AVRs. Then close them back up to test. How on Earth can swapping AVRs on an identical pair of generators cause both of them to lock up at a certain point in their rotation, but still be able to turn backwards??? My head hurts. Can’t find the logic here.

RE: Basic Question About AC Power Wiring

Problem came back. Watched the external generator brown out to 90V. During a warm day yesterday after a couple hours running the air conditioning. Was able to finally do a comprehensive test of everything since it stayed at 90 for a long time. Confirmed the on board generator is functioning ok. Not perfect. Needs to be sped up. It’s putting out 110/109 at 56hz. But the power is stable and working properly. The wiring is not currently an issue from the external generator to the air conditioner. The wiring inside the external generator isn’t an issue. That leaves one and only one thing to be the problem. The AVR inside the generator is misbehaving. That’s why it’s so intermittent. It’s an electronics problem. Replacing the AVR as soon as I can get one. Not sure what a AVR is but I’m glad you’re on top of it...However as I recall this malady occured when using either generator - is this not the case?? 3 tons The AVR is the electronic circuit board that replaces the capacitor in modern generators. Like most things electronic, it’s a piece of junk. Ha ha But yes. I had initially thought the two generators behaved the same because by crazy coincidence, the onboard onan genset decided to cut out at the same time the other one was misbehaving. I like to post a conclusion to any threads a start so that if other people run into the same problem, they find an answer.

RE: Basic Question About AC Power Wiring

The problem seems to be gone. Had a good afternoon of generator running to run the air conditioner. External generator was at 120 under load at 58.5Hz. I left it there. That seems to be making the transfer switch happy. I think the onboard generator deciding to shut down a couple times may have been some kind of fluke. So it’s working, but I don’t have a full understanding of what happened. Possibly all the wires I tightened played a role as well.

RE: Basic Question About AC Power Wiring

Status report: Since the problem is transitory, it’s going to take a long time to test. I got that plug in voltmeter from up thread. I also got a new multimeter for testing. I tightened every single connection everywhere throughout the power system. Immediately on startup of the generator for fine tuning, I saw 70 volts on the plug in meter as it cycled on and off about once a second. No appliances at all were on except he battery charger, which is tiny and a default. While it was cycling and not harming anything I checked some connections. Once the issue went away, I finally did what I had set out to do which was to adjust the generator speed to get perfect power. It was at 108 which is a little low. The frequency also was low. I moved it around but and ended up at 120v and 58.5Hz, under the load of the electric hot water heater. Good power. I couldn’t get exactly 60Hz without going above 120v so I stayed at those figures. I haven’t seen the issue again yet, but have only used the microwave very briefly. It hasn’t been air conditioning weather in Florida lately. Ha ha. I’ll update with new info in case anyone else has a problem like this.

RE: Basic Question About AC Power Wiring

I find it odd to be the transfer switch since both the utility cord and on-board generator have the same issue. Maybe start with isolating some circuits like setting the fridge and water heater to propane only. You are not understanding a Transfer switch and also HOW the OP is doing his 120 power. 1. He states that his ONBOARD Gen is having the problem 2. He states his stand alone genset has the same problem 3. YES, his Stand alone uses the Shore power cord 4. BUT!!!!! His Stand Alone STILL uses the ATS relay with its contac points. The INPUT points are on BOTH sides of the relay. So, over the years he has probably pitted the points on Shore side and also on On Board Genset side. That is why I suggested he BYPASS the ATS and wire direct. That will determine very quickly what his problem is. Doug Exactly.

RE: Basic Question About AC Power Wiring

Most transfer switches only uses logic on the auxiliary power supply. The OP uses shore power to feed rig from portable gensets. Transfer switch logic would also not cause brown out type issue. only thing in transfer switch that could cause problem is contacts. This little tidbit is just the kind of stuff I was hoping to learn on this thread. Thank you. That was actually my first guess. The contacts.

Maybe start with isolating some circuits like setting the fridge and water heater to propane only. Way ahead of you. Being off grid/boondocking, it’s always all set to propane. Generators only come on when we need to microwave or use air conditioning. The rest is propane and solar.

RE: Basic Question About AC Power Wiring

If your transfer switch is readily accessible, you might try connecting your shore power cord wires directly to the wires going to the distribution panel using wire nuts. The using portable genset see what happens. By doing this to take the transfer switch out of the equation. By passing was suggested by others, X2 “Unfortunately, I’m guessing I’m down to eliminating components at this point.” Since it happens with either genny I would doubt it’s the shore power cord. Do not dismiss connections at the main panel and the possibility of a defective main breaker... 3 tons Ok. That’s what my post was originally about. I asked how the wiring went coming into an RV typically. . Main panel? I just have power coming into a circuit breaker panel. That panel has a main breaker which may or may not be bad. I tightened and checked every AC connection on the panel. And on the ATS. Everything looks like it wires directly to the ATS first. No main panel. Just the one panel. I’m down to isolating components and the ATS is the first one I need to do.

RE: Basic Question About AC Power Wiring

Exploratory done. No results. All wires to ATS and breaker panel tightened, paying special attention to neutral. None of the main supply lines were loose at all. I was able to get 1/2 or 1/4 turn on a couple neutrals and hots in the circuit branches. All wires to and from the ATS were securely connected inside. I scraped the connectors inside the ATS a little bit to see if maybe they had some corrosion. Unfortunately, I’m guessing I’m down to eliminating components at this point.

RE: Basic Question About AC Power Wiring

How would that be possible when the behavior happens with the air conditioner OFF??? AGAIN, IT’S AN ELECTRICAL PROBLEM My Mistake, Thought he said it happend with Air Conditinoer on. Ok true story time Now in my case it was the A/C's (50 amp rig 2 of them) sometimes one worked, sometimes the other, both or neither. First stop on the tribble search was the power distribution panel (Breaker box) also, as it turned out, the last stop. The wires clamp to the bus bars and to the breakers with screws. One of 'em took over THREE FULL TURNS before I Called it tight. The result of this is I have a saying: Many RVers have a few screws loose And no you know EXACTLY what Screws I'm speaking of. Mine took either a #2 Phillips or Square (Also #2) square worked best As my favorite RV-Girl (That's the license plate on her work van) says "When I tighten them they don't come loose" (We think alike on many repair jobs). Excellent! My first stop because it’s so easy. Sorry to have been short with you. Up thread I had just got done saying it was an electrical problem a couple times.

RE: Basic Question About AC Power Wiring

You could also eliminate the transfer switch by connecting power directly to your electrical panel and see if the issue is still there. Check to make sure your Neutral connection is tight, breaker is not shorting out where it snaps onto bus bar, and also lug where your 120v line connects at bus bar is tight. Definitely. Thank you. I’m going to work through this ASAP on a cool morning. Maybe tomorrow

RE: Basic Question About AC Power Wiring

Consider a voltage monitor so next episode you can just glance over and observe. https://m.media-amazon.com/images/I/51-wdZF0M7L._AC_UL640_QL65_.jpg width=300 https://www.amazon.com/Monitor-HOMREE-Voltmeter Done!!! That’s a good idea. I can never get my meter on it in time. Being able to instantly see will help a lot. It’s arriving tomorrow
