I would start with a can of gasoline and a short piece of hose to place in the can and other end directly connected to the fuel pump. If the pump now pumps to the carb, then I would look next at fuel filters, then at the fuel line. If this fuel line has never been replaced and the coach is 18 years old, at that age they have a tendency to collapse. Of course if the can fuel does not pump, then the pump would obviously be bad, much easier to test first before going to the trouble of pulling the fuel pump.

Probably the Generator at this stage of the game. Unless this is an inverter generator, the rpm should not change, but yes more fuel is required to keep at the same speed, therefore the governor does call up more fuel which will make a definite change in the sound. As Rich said a frequency counter would be helpful in determining that it remains at sixty cycles.

Brett, you are correct if this an RV generator, most 5500's are only 120 volt, that's why there is a 25 amp and a 30 amp breaker. I don't know what model he has, or if this a 30 or 50 amp coach. Onan does make a commercial model 5500 that is a true 240 volt, and if this one is, the breaker would be double gang attached together. The thought that I am having is that it is a 120 volt model, and that both AC's are on the same leg causing an overload condition, but that doesn't explain why the breaker on the generator isn't tripping. My only other guess is that there is some type of intelligent device that is supposed to shed loads is breaking down instead of doing it's job.

The only other concern that I have is that the inverter is set for 240, is that sometime possibly you have used a 30 to 50 amp pigtail in order to be plugged into a 30 amp pedestal, in this event the current is only 120 volts because the pigtail breaks out 120 to both L1 and L2. In this event the inverter may have "starved" for voltage. In this event, the inverter should sense the shortage and simply shut out the supply, if it doesn't, then that would be a fault in the design of the unit.

Jason, what else is running at the same time that you are running the two AC's? Brett was typing at the same time as me so I deleted that part of my post. Well one other to add, while checking the ATS, be sure to check the voltage between the red and black connections.

There are several inexpensive wireless rearview camera systems on e-bay that would work very well.

Sarasota to Tampa is 61 miles, there will be more choices in Tampa. You may also want to check with a mobile tire service, they are usually available 24/7.

Yes have heard of that, Brett and Joe have posted on that issue before, it was posted in this post, maybe they will be back on soon. As Carl said, WELCOME TO THE FORUM. My First Experience With Coach-Net

Thanks Carl, the single wire is not to help with inverter issue, it only will help get rid of the AC tingle when touching the metal of the coach while in a wet condition.

If no continuity between ground and neutral with coach unplugged from the pedestal, this is correct wiring. The ground and neutral are bonded at the pedestal, which is where that is supposed to happen. This condition will now show continuity all the way back into the coach with shore power plugged up, throwing the breaker at the pedestal will not effect the continuity reading back inside the coach as the breaker only opens the two hots (L1 and L2). Electricity will use the least resistant path to ground in all cases. If there was continuity while unplugged between the two with the inverter in place, then the culprit is the inverter itself. I noticed in the manual that the battery DC wires must not touch the AC wires, this can be another source of backfeed, not their words but mine, this is a known fact.

Rock collectors seem to have the most problem with this, don't believe it, ask Rickey. The long long trailer, 1953.

Keith, is the computer a desktop (stand alone computer with separate monitor) or laptop? If laptop, what brand and model? There are chargers available for some laptops that can use 12 volt DC and transforms upward to 19 volts.

Bearings in rear axel?

That sounds as though 120 applied to either L1 or L2 and 120 applied to common/neutral with the common input into the other leg of the 240 circuit. Everything that was in the on position of the hot leg would have received the full 240, ouch!

It doesn't matter that L1 and L2 (red/black) are inverted in a 240 volt circuit, both are 120 volts to common (neutral), either side will do just fine. The neutral making way to ground after leaving the CG post is still the most likely culprit, by the way if you want to ground the chassis directly to the pedestal by means of a separate wire, simply use a single wire attach it to the chassis and terminate the other end to the round of a standard 120 volt male plug, plug this into the 120 outlet on the pedestal, breaker can be on or off as you are only using the ground anyway. The generator is most often a culprit of this grounding to neutral because many don't realize that it makes a difference, I have even found times that someone put a strap from the generator straight to the chassis. Inside all breaker boxes after entering the coach as mentioned earlier there must be separate ground bus which must not be bonded to neutral in any manner for safety sake, remember that there is an equal load as the appliances on a circuit carried back to ground in a 120 circuit, ie. if you use 5 amps, 5 amps are carried back to ground, enough to cause that tingle when you are standing in a wet condition outside the coach. One other thing that I forgot to mention earlier to test for backfeed to DC, set your digital volt meter to the lowest setting, make sure you are plugged into shore power, and turn on several high amp draw appliances, now hold the test leads to your 12 or 24 volt DC source that powers the inverter, if you read any AC voltage, that is backfeed, it should read no voltage at AC. An analog meter will not show this because there is too little voltage for you to be able to see the movement. Hope this helps, and the chassis to ground has helped several with bus conversions over the years.

Just the valve, the dryer appears to be in very good condition outside. It actually has a nice guard underneath that looks like took most of the winter blunt.

There should be absolutely no continuity between green or chassis to neutral. If you are seeing this, then there is a problem. Could be a blown diode within the inverter, or within any circuit breaker box someone may have accidentally placed a ground wire to a neutral bus, there is supposed an additional bus bar everywhere in the coach, this is only supposed to take place at the the CG pedestal. Since your batteries negative are supposed to be grounded to the chassis, if ac gets to the chassis at any point other than the pedestal, it will cause the feedback condition. Sometimes this condition will actually cause that tingling sensation in wet conditions, don't want that to happen. The surge guard is not supposed to bond neutral to ground, as mentioned earlier this should not happen before the campground pedestal, although there may be an electronic circuitry to make this happen in the absence of electrical connection, without schematics of the surge guard it would be hard to tell. One other place that comes to mind, the generator is supposed to be mounted in rubber with no metal touching the bus chassis or not even bonded with a wire, the green (ground) wire on the generator should be attached at the transfer switch ground circuit, I have seen over the years an installer put that wire to neutral which is incorrect.

Joe, I was in the insurance sales industry for two years, I got out of that for the same reason that you left dealerships. I started to call you last weekend, had to change out the dryer purge valve on my coach, stuck open, ouch.

You may want to also consider adding extra batteries also, as Lenp pointed out that 10 amps at 120 volts consumes at least 100 amps, I usually calculate 20% extra for the overhead of the inverter, as it uses some of the 12 volts to actually invert to 120 plus fans for cooling. If your coach was designed to use only the onboard 12 volt appliances, then extra 12 volt capacity will be needed to power the addition of the 120 volt appliances. You may want to actually incorporate a stand alone scenario for the inverter purpose. If you decide to go this route we will be happy to advise what will be needed to acheive this goal.

Bill, sorry to take so long to get back. AC feedback is a term used meaning that there is a ac entering the dc side of the device, meaning of course that there is probably a neutral side of the ac circuit somehow touching or maybe miswired and making way to the frame of the inverter. With shore power disconnected and generator not running, test for continuity at the two blades of the shore power cord, neutral and ground are the two blades. Continuity can mean any amount of resistance between the two, not just 0 ohms, if this occurs check for bonding al all junction boxes, there should be none, if there is that will be the source of the feedback. If possible please include the model number of the inverter.

Bill, I use IE11 and your signature appears there. I just logged in with chrome, your signature was not there when not signed into my account, logged in and viola your signature is now in chrome. Suggest that you log out of your account then log back in to see if it comes back.

Bill, is this a 240 volt output inverter, or is it a 120 volt inverter with two connections? The inverter should be labeled either 240 or 120 volts, also how many watts is the inverter? Will answer the first question when I know the specs on the inverter. Also, is there any device in the coach which is a true 240 volt device?

He probably wishes that it had been his Sony instead of the hub cap. He wouldn't be worrying about the gorilla tape coming loos anymore.

Yes, there are ways to parallel, or stack by using a parallel harness. These devices are designed to electronically set the phase between the two or more inverters so that they are perfectly in sync. And in most cases the inverters must be of the same size and manufacturer. Honda inverter generators are famous for this as they were first to use this technology.

Since 12 volt side is direct current, it would ok to have both of them to charge the battery bank at the same time. And with smart technology, both will be sensing to prevent an overcharge situation. What will not work is for both inverters to supply the same AC circuit at the same time, that would in almost any case cause the inverters to trip because of the inability to be in perfect phase with each other.
