I use this in my Rv repair business. https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwid56bwoq3gAhWNwmQKHXS0AkIYABAIGgJwag&ohost=www.google.com&cid=CAASE-RofQExxp4-kxFkEpLt6zeaetQ&sig=AOD64_1h97Cd2h9CeX36279Q-mm2MT48Qw&ctype=5&q=&ved=2ahUKEwjo6qHwoq3gAhXAHTQIHb_9Cb8Qwg96BAgIEBM&adurl= I normally tell them about it or if I have some on the service vehicle, I give it to them . Just fill the bowl with water, pour a tablespoon or less in and let site. I have let ours get really bad for a test. It took 12 applications, but never taken it apart in 7 years. If you scrape it do not call me to fix it. Vern

I will suggest to put something like cardboard under the exhaust area under the coach. Put.it on the ground and make sure it cannot move up against the exhaust pipe. Then fill the system and operate the unit. If anything is leaking from the unit itself it should come out of the drain pan around the exhaust pipe or the intake air screen area. It maybe leaking from the rear of the unit where the hot water exits the unit. I had one last summer that was doing that. just a thought ,. Vern

On the unit that I was working was apparently a profit rig. Never did find that fuse. Now what was the real problem was the sense wiring for the alternator had a bad connection. That connection was over in the passenger side of the engine compartment. I do not remember exactly where. It was in a box that had relays inside. But when talking to the tech person at the rebuild facility recognized that I was working on a motor home. He was the clue where to look for the end of the sense wire. And no it was not to be at the batteries. Just a thought, Vern

Now this little trick may or may not help. There is a little 1/4" drive screw holding the ignight assembly to the tank. It is on top. Loosen that and tighten it. Maybe three times. Now another little trick for that style water heater is to make sure the igniter wire is not touching the outside door when the door is closed. You can look at the door on the inside and possibly see a trace where the wire is leaving a mark. just a thought,. Vern Dino board would be better also

Customer has a build sheet for said Rv. It calls for a 500 amp fuse. Engine alternator was producing 17 plus volts. Killed the chassis batteries. I think. So I removed the alternator and ordered a rebuilt unit. Got my tone generator out to follow the battery cable to the inverter. My batteries in the tone generator were dead. Tomorrow is another day. Buuut still no sign on a fuse. Vern

That may be

I am working on a 2003 Monaco Dynasty Motorhome . I cannot locate the fuse between the inverter and the battery bank. Both me and my customer would appreciate any advice where it maybe located. There should be a large fuse, say 300 amps or more in line from the inverter and battery bank. I have called several tech phone numbers that I have. Just for general info on Monaco and related coaches, Rev RV no longer helps with older coaches. Thanks in advance,. Vern

First thing I would do is to unplug the unit from 110 vac. Make sure the fridge is turned off. Then pull both fuses and polish the ends where they make contact in the board . Check for dull finish on the fuse holders. If dullness is there polish the contact area. Next if you at the wire ends on the right of the picture that attach to the board. The white cover will open up so you can test the power to those wires. Use a little hook to open them up for acces to test power. Now plug the unit in and operate it on 110 vac. Test to see if 110 vac is going to the heating element. And test all testable spots for 110 vac to the heating element. Then test amperage to the element. Now use two weeks ago I had a customer call and his fridge would only operate on gas. Another mobile RV tech said the contro board inside was bad. I check real quick for 110 vac as I am telling you. I had another board for the control inside the fridge. Installed it and still no amperage to the heating elements. Hooked the elements directly to 110 vac and the elements worked. Installed old control board inside. Did fuse test polish and replace. Finally took a pair of pliers and twisted the plug ends that plugged into the 110 vac. Installed plug back into outlet. Fridge is still operating on 110 vac today. Just saying if you have the system operating on 110 vac and have the fridge on auto you can unplug the 110 vac plug and it should switch to gas automatically. That is if the unit is calling for cooling operation. Safe Travels, Vern

If you had a tone generator you could trace where toes wires go.https://www.amazon.com/Extech-TG20-Wire-Tracer-Generator/dp/B00APD16D2 with the power off you could find where those wires go. Just used one the other day to trace a wire to a jack controller on an orphan rig. Safe Travels,. Vern

Try this, http://www.twinslan.net/~n0nas/manuals/onan/ I hope this helps. Some times my iPad mini just takes me to the correct site. My 1970 Miller welder generator that has a on an gas engine is even in the documents. Safe Travels. Vern

I finally remembered the other name. Flight systems, they doe repair boards and make some aftermarket Oman boards. Did you take a look at the Twinslan site . Vern

If you search Twinslan.net Lockmup, You may find your service document there. Kirk you may want to save this site. Now you also could contact. (. ). Really this name is outside floating around somewhere. When I find it I will post it. Safe Travels, Vern

Great idea for the crime committed Vern

After driving on some ice on I -90 just west of Butt Montana on Tuesday , we are at Nephi Utaw. On I-15 at Mike marker 222. 337 or so miles from Clark county shooting preserve in Las Vegas. Hopefully be there tomorrow night. Vern

Check and see if your outside shower is turned off at the handles. Also when it is not producing heat see if the pump has stoped working for the zone that is calling for heat. What year is your coach. See if you have 105 model pumps

You may have an issue with the sensor for the domestic hot water tripping the heat off. They do that so that when the hot water is used the heat shuts down to save the energy for the water. Just a quick thought. Vern Do the fans still blow air. If they do you may have a pump problem.

If you have trouble with a Atwood water heater, that will ignite, but then the flame goes out. It most likely the little 1/4" screw on top of the burner tube that holds the igniter assembly on to the burner tube. The board is not sensing flame because of it not having a ground for the sense probe. When there is a flame covering the igniter probe and the ground probe it send a signal to the power board that there is a flame. It does this by send a few milivolts to the power board. Loosen the screw and retighten it three times. And then try the water heater. Just a thought,. Vern

What engine do you have. That would help for info. Vern

Yes that is it. I could not get it to copy on this forum. Thank' s. Vern

This company provides rv's for the movie industries for movable living quarters. The were sold to Quixote studios. But they have mid 2000' s Tetons that are remodeled. So if one wants to remodel your RV, this will show how much things can change. Sorry there is direct link but this site will not let me post a direct link. Safe Travels,. Vern

In real world expierence With the power to the fridge disconnected, disconnect wires to the heater, plug the power in and repeat what sequence was making it blow the fuse. See if it does or not blow the fuse. That will determine where the problem is. Board or heating element. But I would bet there is a problem with the element shorting to the side of the heating element . Remove the heating element and look for a swollen area on the element itself. You could check the ohms on the unit. Also check wires to ground But I have seen them be intermittent and really make you think. It can test good but still have its fits and occasionally short out and blow the fuse. If you try and wiggle the element when it is cool and it is stuck or hard to remove that is an indication that it has a problem safe travels,. Vern

That gps thing did it Renee, Keep quite about our plans. Big 5r may find me. And that blank problem has with me may catch up to me. Be nice Big 5r,

Leaving Florida forever. Someone tried to steel our jeep while it was in a well lit area just in front of our 5thweel. So off to Arizona. Vern

We are now hiding in Florida. We may just make an appearance at the Tampa RV show. But we are going to hide for some rest this winter. Safe Travels to all, Vern
