Electrical Help!!

I realize I may have posted this in the wrong section so I am copying it over here:


Electrical HELP!!!
Here is my issue. When I plug into shore power (most times), I get a "HIGH VAC IN" fault in the Magnum inverter, and all the 12V stuff is barely lit- most lights won't come on.

From basic troubleshooting I've found that I cannot have 2 breakers on at the same time, which are these:
1. Progressive Dynamics Conv
2. ODS
I don't even know what the ODS is connected to or where the converter is located. I can't have these two breakers on at the same time, and I have no interior lights that way!

I would sure appreciate any suggestions! I have already checked all the breaker connections for being tight as well as all the battery cables. I also checked the AC connections inside the inverter.

Thank You!
Mark

So- Lights are OK if you turn the battery switch back on when troubleshooting..oops.

Problem is something on the "ODS" breaker circuit- anyone know what the heck that is??

So I know that both the ODS and Prog Dyn breaker are making the outlet in the Microwave cabinet hot, one on each side. Wonder how this just 'started' happening after a few years????

One thing that would help us is the year and model of your coach, and are you the original owner or subsequent owner?

2015 38RL. I'm the second owner, but this problem just popped up. I've been on 3 trips before with no issue...

I believe ODS means off door slide, which on your coach is the driver side kitchen slide. Please try and list all problems and symptoms. Some part of your symptoms may have been the battery switch was off. Do you have a surge and electrical protector? If not do you have a way to measure battery voltage. I think you can energize the hydraulic jacks to read the current battery voltage. These things will help you diagnose the problem.

I ran thru all the breakers individually. The problems is I have a few neutral (white) wires that are getting hot, so there is something touching at some junction I suspect...

There are three breakers that make the inverter neutral in and the nuetrals on the fireplace and living room circuits at the connection underneath on the slide hot.
1. Ceiling Fan/Bed
2. Living Room
3. Progressive Dyn Conv

I can't find all the junctions underneath, but I assume one spot there is a black wire exposed to a neutral. I have the underside cover open a little and the basement wall out...

I know those goofy clear plugs at the rear slide have been an issue, but I am checking the feed side with those disconnect.

Any suggestions on junctions/locations to inspect?
Thanks

sounds like your park power has a issue or possibly your automatic transfer switch . I think you have a open neutral on the incoming power. running anything for length of time with this condition will ruin electronics. Get a voltage meter and check your incoming service . Open white wire and a slightly unbalance load will show roughly 90 volts hot to white and 150 volt to white on the other leg. you should have less then 10 volts from white to ground.


my inverter on our RL is located on the driver side basement , check the voltage at the input side of the 120v. You could also try disconnecting the park 120/240 volt power and then disconnect the 12 volts DC from the batteries . I have had my Magnum give me a few codes the needed a cold restart to clear.

With only the "ODS" breaker on, I get 120V at the black wire that is going to the inverter input, and nothing on the white.

When I connect the black supply wire to the input on the invert, both the black and the white output side of the inverter have 120V.

Something must be gone in the inverter...?

No experience on inverters since our RW has a Norcold refrigerator. But ‘DS’ stands for ‘door side’ and ‘ODS’ stands for ‘off door side’. So the breaker labeled ods is for 110 volt wiring on the off door side of your coach. Hope that helps some.
