Generator Now Running but……. more issues.
Finally got my generator running. Put on new filters re-bled and she started right up.
The last two months or so I have had my bus connected to Shore Power. Well I have looked at my genny voltage gauges for the last two months while plugged into shorepower and they have been perfect at 120 Volts per leg and 60 Hertz.
Today when I started the Genny everything looked great on gauges. Keep in mind bus still plugged into shore power.
I un-plugged shore power to take bus out and I get a warning instantly- ‘DANGER- SHOREPOWER REVERSE POLARITY’…… This is with the genny running and un-plugging the bus.
1) Why does the bus still think it is plugged in and giving me this warning?
Now when the genny is running I am getting above warning and leg one on gauge is pegged at 150 volts and leg two is showing zero.
I am getting worn down by all this. I would take it to a shop to simply have all these electrical issued taken care of but there is nothing in the Chicagoland area. I do not want to pay someone to learn on my dime.
Sounds like a ?
Any ideas or input?
Help!

You could take it to Royale Phoenix in Elkhart IN call them Glen Bergen is a electrical genius they have a shop not to far from you they worked for royale for years and have a shop that works on prevost give them a call he will know when he tests it 1-574-206-1216 work or cell 1-574-612-6057
Liberty is in Chicago do not know if they work on anything else but Libertys Jeff Rowes is not that far from u either he is in Knoxville 541 miles away from you I would take it to him first if that’s to far take it to Glen in Elkhart IN either one will do great job for u they are 112 miles from Chicago to Elkhart

Thanks for the follow up I think that’s an awesome recommendation. At this point I don’t know where else to turn in going to take a pro to check this thing out. They do all types of electrical like inverters house batteries etc.?

Yes they do they have done work for me on my Royale I put how far it is from u on the last post there is two guys there Glen and Dan they are both good

My guess would be your transfer switch did not switch neutrals as you disconnected shore power with the generator running. I’d disconnect the generator via breaker. Check if voltages are ok on inverters. If so, connect the generator breaker. If problem reappears, I’d suspect the transfer switch.
A bad neutral connection will cause very weird voltages on split phases. The voltages will depend on what devices are turned on. Very easy to fry your appliances and electronics.

I have a 1990 Country Coach- will they work on something that old and not Royal related?
Yes, the Nasville it a little too far.
I just do not want to take it to an RV repair facility and have them “try” and see what is wrong and end up with a HUGE bill and a “we tried to give it a shot”… sorry.

I think so they work on all kinds of prevost

Thanks for that lead… I am going to check into it.

Tully,
I assume you have an automatic transfer switch. Your current problem does not sound too complex and I agree the focus should be on the transfer switch. There are times (often due to inactivity) that some stuff on our coaches doesn’t work as intended, but cycling the devices often loosens up the device and gets things back to normal.
Most of the time it is the suspension Norgren valves that suffer from inactivity, but I can envision a contactor acting up also. The training on your dime won’t be done if you use a shop that has a background in your conversion. I know Jeff Rowe has the experience because his former employer was a dealer for CC.
However, if your coach was “updated” to have a transfer switch or to replace the original or if someone updated the inverter systems whoever works on the coach is going to have to first understand what was done if it was modified. Your coach is of an age that the original systems could well have been modified.

has anyone found an amount of time that having their coach sit without system use, that there is a system exercise timeline that helps keep things operational and in a working order. If a coach sits idle what would be the exercise regiment that people suggest for it.
Not sure I am asking this correct, but sure folks will understand what I mean.

It is our practice to stop traveling in spring (around April) and not resume travel until September. The coach is in our garage, sheltered from temperature extremes, but rarely touched. I do not start it, use it, but generally fiddle with it meaning I will do maintenance, make needed repairs or make mods we decide we would like.
Usually when we are ready to travel I start the bus and we head on down the road with no ill effects from the inactivity. We have had lazy Norgrens such that when I went to level it it would not respond, but cycling through the range of motions the coach begins to operate as it should. That has happened maybe twice in 24 years.
I do not start the engine unless I absolutely need to, usually to check for leaks after replacing filters. If I do get a burning desire to start the engine for other than maintenance then I make sure I am driving long enough to heat everything up fully, usually at least 50 miles or more.
That is only my experience and by no means do I think that is typical. There are too many variables.
