No power on right side of bus.

[LarryB]

Denny, I saw your post on the other thread and just now found it here. Sorry I missed it---trying to attend a reuinon and trouble shoot this Bus I'm spread thin.

I will be back in the World today and will have the inverter checked out. All the breakers, CBs, fuses have been checked so it seems to be down to the inverter.
The problem is the same as you describe so, it seems logical to have that inverter checked. I am wondering if the 'Reverse Polarity' incident cooked the inverter? I was thinking that power never made it onto the bus and was stopped by the Surge-Guard.

Thanks for the info.

Larry, Just a thought. Have you checked all your GFI equipped plugs especailly on either side of the bed? We had a incident with CC #60449 when we owned it.

[LarryB]

Jim, yes we hav e checked all GFI in the coach. Thanks for the thoughts.

Was going to start a new thread but found this one that is right on target for my problem.

I have one inverter "out" somehow right now too. I have been trouble shooting. I've read through all the posts. I checked GFI already and I'm getting power through the J class 350 amp fuse ok but what I seem to notice that is most strange is that when I took off one of the terminals on that aforementioned J class fuse, the remote for that inverter didn't go blank. The LED's where still lit up. The "A/C" in light is on. My Levitron surge protector went bad about a month ago and I haven't replaced it yet which was unwise but I THINK that component should be replaced and yet not essential. The one inverter (passenger side if it matters on a Royal) was just working a few days ago.

I changed out my batteries but don't THINK anything bot mis-wired but I'm going to look at it again now. I'm in the bus and traveling so I'd really like to sort it out. At least the fridge, TV work but the main inconvenience is the toilet is out.

Would it be a major no no to turn everything off and take the terminals off the J Class fuse, then put some jumper cables to those terminals off the 2nd (good) Inverter at the J Class fuse just long enough to let me get the toilet fllushed until I can find the real culprit ? I can use the bathroom at the RV park until I sort it out but the potty.......it be stinky. I won't attempt that until I get a reply here. That might be adding insult to injury.

I just went out and tried something before hitting "Submit". I have a Progressive Industries Surge protector Mode: EMS-PT50C that I have not been in the habit of using. I just went and put that in line and it would not let power to the bus. I tried to video the codes but I did it wrong so I have to go back out and get the codes and check the owners manual to see what's up but meanwhile, is that a blatant clue ? I also check the inverter with the generator on and on batteries only and no change. The part about the remote staying on when I disconnect that one J class fuse has to part of the problem I would think.

Jeff. Is your toilet 12 or 24 volt or 120 volt? The inverter is for 120 volt loads. What else is not working?
It sounds like yo have identified several issues;
1. Your shore power surge protector no longer works. Are you still getting 240 volt into the Panel?
2. Your buss fuses on the battery side of the Invertor is OK. These batteries are usually in parrallel so your going to get readings on the battery side of the fuses.
3. You can not get correct voltage from the shore recepticle to the bus. Hve management test shore power.
4. You checked Generator which when started should run all 120 volt loads as well.
5. You replaced coach batteries recently. Check wires.

So, it sounds like a transfer switch problem, circuit breaker, or possibly a reset on a inverter itself.

Larry,

This will help make sure the power is clean before it reaches the bus.

Mike- That is the same unit I have however it's spent it's life in the box until yesterday when I put it in line to help troubleshoot. With that very surge protector in place, it wouldn't allow any power (on either side) to pass through). I just moved to a different RV Park and am getting back to troubleshooting again. I put the surge protector in line and a pen to go record the codes. I could hear that no roof A/C's went back on so I went inside to check the inputs on both inverters. Then, the power kicked on. Upon further reading of the owners manual I now learned that the surge protector takes a pause before allowing power through. So shore power and generator power are both eliminated as I also have input power on both legs on the panels.

I think I may have a bad GFI on one of the 110 outlets. I'm not sure but I'll explain.

Each side of the bus (on my Royal) has multiple 110 outlets of course. Only one of them as a GFI outlet. If that GFI is tripped, all the other outlets loose power also. We'll the GFI on the passenger side (the side I'm having trouble with) is not making any clicking noise when I push it from Test to On like the other (working correctly) does when I "Test" it.

Question: If no power is being supplied to that outlet, should I still be able to detect a clicking upon toggling the buttons ? I don't know. There is no clicking so I don't know if it is because of no power thorough or bad GFI.

(Answers to Gary's Questions follow)

Jeff. Is your toilet 12 or 24 volt or 120 volt? The inverter is for 120 volt loads.
>>>> When I read this I thought "Hmmm. I didn't notice anything electrical at all on the toilet when I removed it and rebuild the guts a few years ago". It's a Microphor. I believe it is totally air powered. I do not have a breaker anywhere for the toilet but there is a 5 amp breaker for the air pump for the toilet on the 12 volt panel. The light on the switch for the air pump comes on, but the pump doesn't come on.

What else is not working?

>>>>> The microwave, washer and dryer, and all the outlets on the passenger side. The TV in bedroom IS working along with all that A/V that goes with it (DVD, Bose, ETC) and that is on the passenger side). Not sure if relevant or related yet.

It sounds like yo have identified several issues;
1. Your shore power surge protector no longer works. Are you still getting 240 volt into the Panel?

>>>>>> Yes

2. Your buss fuses on the battery side of the Invertor is OK. These batteries are usually in parrallel so your going to get readings on the battery side of the fuses.

>>>>>> Not positive what you mean here but I do believe I've eliminated those fuses as being the problem.

3. You can not get correct voltage from the shore recepticle to the bus. Hve management test shore power.

>>>>>> Addressed I think and shore power at two different RV parks with same symptoms. Same symptoms on Gen power as well.


4. You checked Generator which when started should run all 120 volt loads as well.

>>>>>>>> Yes

5. You replaced coach batteries recently. Check wires.

>>>>>> Checked. However could possibly still be something in the battery bay. Still trouble shooting.


Further: My inclination is that it is not an inverter problem but I'm not sure. There is a tiny red LED viewable on the interior of the inverter though the grate. It goes on and off when I turn the inverter to the "off" mode on the remote as it should. It's just the toilet and the passenger side outlets and the microwave. Water pump working and everything else that I can tell. Continuing the battle and trouble shooting.

Any input on the GFI not making the clicking would be very useful. Replacing that is an easy and cheap attempt at the remedy even if it wind us not being the problem. Will check back here and wait until tomorrow for any additional input however before changing it out.

Jeff,

On my Royale, The secondary panel in the bedroom that feeds all the circuits from the inverters has a yellow button on each breaker. I have had trouble with 2 of the breakers occasionally tripping when going from 1 power source to another. ( gen to shore, shore to Gen, etc). When that happens I lose one side of the bus. Reseting the breaker has always worked for me.

[MangoMike]

Jeff,
That unit takes about 3 minutes to check the voltage and initialize itself. You'll see a blinking dot on the display as it's doing it's check. Once the power starts flowing thru the dot will stop blinking.

Initially I thought mine wasn't working either.

Mike

Had I read the rest of your first paragraph, you're good to go.

Hi Jeff. The GFI will not re set if there is no power to it. you will have to unscrew the gfi to test the wires at the back of the recepticle. But, because your microwave, washer/dryer do not work, it has something to do with your panel power. Have you tested your transfer switch to verify you have 240 volt to your panel?
It is more than one circuit so it is possible it is your inverter, but I don't think your washer/dryer are on your inverter.
