Wayne,

I only have two breakers that are labled Battery chargers. None are labled "Inverters". I checked all the breakers and none had tripped. This is a real puzzler. The fact that the voltage is rising on the driver dash guages disturbs me. It is at 17 volts according to the guages but I measured the voltage at a lamp socket and it was 16 volts. That is still too high for a 12 volt bulb. One has blown already. I don't know why the voltage is rising like it is. It is a very slow rise. It started rising yesterday when we parked at this RV park and between 2pm and 10pm it had risen from 14 volts to 16 volts. and today as of 9:30 PM it is slightly over 17 volts.

If I am going down the road with the engine power it is 14 volts. Go figger.

Did you check all the breakers in your 120 volt panel, sometimes you can't tell that one is tripped and your two inverters should be on 2 seperate 120 volt breakers.

Pete,

I have checked the pop out resets on the two Inverters and they were all in so no need to reset them I pressed them anyway just to make sure and they were solid in.

What switch was it that you accidentally hit. I have looked at everything on the dasboard console and didn't notice anything that jumped out at me.

It appears that a breaker has been tripped. I did check those 4 breakers you mentiobned and tripped all of them off then back on and it didn't chanbge a thing. The Inverter panely that is next to the drivers seat (two of them) , the bottom one is off. No indicators are lit at all. Evidently your coach has a different Inverter than mine. Mine is a Heart Interface, Freedom, Model # 25.

I think the Inverter has a breaker tripped somewhere. I have some 120 volt outlets with no voltage even though I am plugged into shore power so that is a clue to the
problem I would think. It appears that the shore powerr has a leg that is non functinbal.

Got to go pick up the wife at the laudry right now but be back shortly.

I had a similar situation not long ago. After troubleshooting, I thought I'd have to replace the inverter. Eventually, I discovered that a switch on the control panel (next to the driver) had been accidently turned off. Turned it back on -- and now it works just fine. (I guess I must have bumped the switch while working with the HWH level controller right next to it.)

I don't know what controller you have -- but a P.O. had installed a (Heart) Link 2000R controller. It manages the power output of the chargers and limits the charge rate to the batteries (I have AGMs and they require a lower voltage than regular wet cell batteries). On the downside, the Link 2000R controller takes an electrical engineer to operate it -- the manual is very difficult -- but I've been able to puzzle out the way to get it set up right for my batteries.

The standard interface is not as adjustable -- but I'm not really familiar with it.

The inverters have a small breaker on the front (inverters are inside a metal box just above the batteries inside the curb side battery compartment) . Push in to reset. There are dual breakers for each inverter. Mine are located in the bedroom on the engine bulkhead below the main 120 V electrical panel behind a carpet covered door (with an obvious handle). (I have a side-island bed.) 2 breakers for each inverter. These protect the inverter from an overload on an inverted circuit since the inverter power is NOT routed through the main 120 V panel.

The back closet has a removable wooden panel which you might think is to access the engine from inside. You would be incorrect. I removed the panel the other day (in exploration) and discovered it covers a bunch (9 or 10) of 120 vac relays. I have no idea what they all serve (I didn't look for a wiring diagram -- I was just exploring). To remove the panel, you must remove about 6 screws in a gray felt covered strip, then remove 4 or so s! crews al ong the top edge and 2 screws further down -- but you probably don't need to get in there for this problem -- you should just be aware it's there.

Good morning,

I guess that when you go out on a trip is when everything really gets a workout. I left Texas 2 weeks ago and I have finally made my way to Eugene, Or. on my way to Alaska. I have had different kinds of problems arise and corrected them but I have now lost one of my Inverters This is not good for the batteries I would predict.

I think that maybe the inverter is fused or has a breaker in the circuit but I have no idea where to look for that.

If there is anyone out there familiar with the Inverter power circuits, transfer swithches, etc. please advise me. I would like to reset the Inverter that is down and see if it will hold.

The type Inverter I have is the, Heart Interface, Freedom Model 25. There are two of them and one is offline. I don't have any schematics with me or location diag!
rams.&nb sp; Maybe someone on the forum can help me in identifying how this system works and where the transfer switches are if there is such a thing on this coach.

My coach is a 1995, WLWB, 42'. There must be a transfer switch somewhere that senses when shore power is available nad turns the 120 VAC from the Inverter off. That may be where the problem is.

My greatest fear right now is that the Inverter that is still powered up is producing 16 volts to the batteries. That can't be good for the batteries I would think. My next fear is that the Inverter that is down will have to be replaced if it can't be restarted. That will cause me a delay for sure waiting for one to be shipped in and installed.

All the other sytems seem to be okay, except for the LPG gas shut off valve that I presented to the forum about 2 weeks ago. I have not done
anything about pulling that panel to see if the main shut off valve is turned off. I don't really have a need so far for it since my generator is now functioning properly.

Any help with this will be appreciated. I am on a WIFI that finally works as it should. I am in Eugene, Or. at the Shamrock RV park located on Old Franklin Blvd. just off I-5. Nice cool weather here.

Thanks again for your assistance.
