Electrical problems still

[larryh]

Just installed a Heart 2000 inverter and was kicking in and out like a short or a overload. If You recall I had problems last year with coach shocking if you touched it and ground in anyway. Well I told electrical about that and told him what everybody said about isolated ground.

Well I just took cover off electrical panel and all ground wires go to the standard ground panel bar. all the neutral  white wires go to a floating bar not attached to ground anywhere . IS THIS RIGHT???

some guidane please I think it's all screwed up

Thanks in advance this is on a 4905 Buffaslo all bus equipt 24 volt but this is trouble in AC only.

Yes, Larry, that is correct.

The easy way to figure coach electrical setup is to consider it as just a large appliance, like a lamp or a toaster. Appliances have a hot (black wire), neutral (white wire), and ground (green or bare wire). The hot goes through the filiment of the light bulb (in this case your coach is the lamp) to the neutral. The ground is there ONLY as a safety factor and is connected to the body of the lamp.

Bonding (Neutral and ground hooked together) is accomplished when on the power pole at the main breaker panel only.

Bonding when on the generator is done at the GENERATOR only.

Bonding when using the inverter is done at the INVERTER only.

The neutral and ground are never bonded together in any other place.

With your inverter problem you may want to stasrt by looking at the 12v connections at the batteries and at the inverter itself. Also make certain you have cable that is large enough to carry the load you are trying to use.
What are you trying to run from your inverter? Is it possible you are trying to start too large a load with it? Items like roof air may only draw 13 amps when running, but can draw twice that much when trying to start.
Try disconnecting all of the loads you have on it and see if it will start. Next, add one load at a time until you reach a point that it starts screwing up. Add up alll the current draw from all the loads and see if you are within the inverters capabilities.

I hope this helps.

Dallas I turned all loads off and inverter is still acting like something is shorted volt meter goes of momentary all cables are sized correct

Larry, since you just installed the inverter, I would suggest you remove all the AC output cable(s) from the inverter to make sure there is not a short in your wiring somewhere. I sure sounds like a short and that would indicate something is not wired up properly.

I have to agree with Richard, it sure sounds like one of the circuits is going to ground

[larryh]

I.ve checked all circuits with a tester all show the two yellow lights. everything runs ok on AC but when I plug into the inverter circuit this problem shows up I redid all output wires and soldered all circuits and no change. Plug into shore power plug and all fine.

You should start with square one and disconnect the load wires from the inverter and see if it works without a load then if that works reconnect the load and then trip all the breakers in the load panel.. then step three is to add loads by adding breakers on one at a time. Jerry

Ok found the problem.

The new ouput wire 6 gauge to plug from inverter was bad shorted on inside wire some place bypassed it and all working as should nhave a heavy wire by passing it in temporary now will fish old wire out and pull new wire after I get up north for grandsons graduation.

He's been accepted into the Navy Seal training he's following his granpa and his dad service in special forces. Proud of the lad hope to be on road tomorrow sometime heaed for the North west coolness.

Thanks for all the input who would of thought a brand new wire problem.
