A couple ?'s about electrical wiring

I was checking out the distribution panel and converter yesterday in my GH31SS, and came across some electrical wires that raised some ?'s for me.

I found a black wire, probably 6-8awg just laying in between the black box w/ the label LPT30 and the converter, and the black wire has the orange tape on it. The end of the wire has copper strands exposed like something was going to be connected (ring connector) but the wire is just laying in the compartment. The black wire leads over to several wires that come from the distribution panel and then goes thru a hole in the floor.

Any idea's as to what this wire is supposed to do. It looks like a main ground wire for one of the systems, but my lack of experience/knowledge with MH's is the reason for the post.





Second ? deals with the black & white wires I found just laying in the same compartment with the wire above (closed off area under the bed for the backside of the distribution panel/ and the converter)




Third ? is:
what are these white boxes that look like receptacles mounted upside down?

Could be for an option that you didn't get. Do you have the inverter?

I agree with GRumpy , have u checked the black and white wires to see if voltage present because they definatly look cut by a tool of some kind

No inverter found, just the black box labeled as shown and the Iota DLS 45 in this "compartment" which is the back side of the DP and it's wiring. I had to remove some screws in the cover to gain access to this area which is under the bed.

No I have not checked to see if any of the wires in ? are carrying current. I think the large black wire with orange tape on it is a 12v ground wire based on size and appearance but since it disappears to the underside of the MH thru a hole in the floor, I haven't tried to trace it due to weather (rain).

Have had been on one trip in the GH, and everything worked that trip, no funny smells or electrical issues of any type. I'm thinking the wiring is for options not installed but feel the wires should have wire nuts on the ends to prevent any accidental shorts/arcing, etc. when in transit.

*Usually* black in the RV world would be the HOT wire, and white would be ground. I would check that black wire to see if it has current to it. Is that LPT30 a transfer switch of some sort? Maybe that black wire is for an indicator and is supposed to be hooked up inside following that white wire?

The black box is the transfer switch. The extra wires probably run to the battery compartment and would feed the inverter if one was ordered when the coach was built that was why I ask. They will not have any voltage on them or at least they shouldn't. The wiring harnesses are usually all the same for that series of RV and there are extra wires for all the various options.

Does the inverter feed into the transfer switch as well?

No. The inverter would have wires coming from the battery as well as to and from the breaker panel(standard 110v wiring either white or yellow). As I said there may be other options that were available that the coach is pre-wired for. If everything is working and the wire in question has no voltage on it I wouldn't worry about it. JMHO

Which black wire are you referring to, the black wire laying in between the black box (LPT30) with orange on it or the one bundled up with the white wire??


So the black box (LPT30) is the auto transfer switch between shore power and the generator correct??

Is there any way to tell "who" made the auto xfer switch, since Iota had a recall on theirs, not all that interested in having theirs in my MH unless it's been replaced, etc.
