Xantrex inverter dead?

[Trendycat]

Thanks for all of the help so far - it appears the problem is a blown fuse - one of the fuses is only showing voltage on one side when everything is shut down and running on inverters only. (Batteries are all fine - I have 6 Lifeline AGM's that are less than 2 years old)

Next issue:

The Bluebird plant cut some corners on the electrical when they built all of the units and wrapped the fuses in electrical tape and clamped them in place rather than using a fuse holder. I would like to redo them with proper fuse holders, but don't have the tools/expertise to make the new cables I would need to reposition and insert new fuse holders.

I asked on the Wanderlodge forum, but most of those guys are big into DIY - so they had no suggestions of a shop to do the work (other than one in FL).

So, any suggestions on who would be competent to do this kind of work and located somewhere on a line from So Cal to Dallas, TX? I had a great deal of non-electrical work done at Prevost Fort Worth in Jan of this year and was very pleased - could they handle this?

Here are a couple of photos of a '95 Wanderlodge with a similar wiring setup to mine. The first photo shows the original setup, the second after the fuse holders have been installed.

Thanks for all of the help so far.

BTW although I'm not setup to handle this repair/upgrade, I am an authorized AquaHot / Webasto mobile service center. If you ever need AquaHot / Webasto parts or service, let me know. (I offer a special discount to fellow POGgers.)

Bruce,

If you want to try to fix it yourself, look for a local NAPA store that carries truck parts. I have had good luck getting cables and hoses made for very reasonable prices.

Here is 1 source for the fuze and holders.

If you don't mind wandering a little farther north to Tulsa Oklahoma, we have good friends at Tulsa RV in Catoosa (suburb to the east) which is completely capable of performing any work you need done along the lines of battery cabling/wiring/fusing. Let me know and I'll look up the phone number for you.

The other scary situation I have seen on Wanderlodge units is that generic conduit clamps, with no loom or rubber or other insulating material were used to fasten down battery power cables to the metal structure of the coach. Over time, the clamps tend to wear through the insulation and poof, literally. The instance I witnessed most recently gave the strongest motivation for the customer to trade out of the coach I think I have ever seen! My stongest advise, no matter what brand/make/model coach someone owns is to have the battery cabling and terminals inspected for abrasion and all terminals tightened REGULARLY. That is probably the only reason I haven't seen more birds burnt up...the fact that most of the owners, being do-it-yourselfers, perform inspections regularly and catch those issues.

Ben,

Thanks for the info about Tulsa - that's well out of the way of where I prefer to be, but if it turns out to be the only recommendation in the area, then I'll try to detour up to there.

I followed the issues surrounding the fires in some of the mid-90's birds last year and checked all of the cables and connections I could see on mine. Strangely, almost all of my cables seem to be wrapped in plastic loom - I don't know whether it came from the factory that way or was done later. My chassis number predates a couple of the buses that had problems and a number of my wiring runs look significantly different than the photos I've seen of those. However, I still plan on having the fuse blocks redone properly (similar to the photos I posted earlier) and all the wiring runs reviewed/checked as thoroughly as possible at that time, as well.

Prior commitments prevent me from making it to FL this year or I'd visit Coachworx for the repairs. I'm trying to get this work done in a narrow window at the end of September / beginning of October so that I can make it back to ABQ for the balloon fiesta - which is why I'm trying to find a shop no further than Texas. I figure I can make the run from Arizona either west to So Cal or (preferably) east to Texas and back to Albuquerque in that window, but probably no farther than that.

Thanks,
Bruce

Again I think this is something Desert West in Phoenix can do for you. Just show them the before and after pictures.

Bruce,

Your wiring loom is original. Blue Bird did a good job with chassis wiring as the evidence points out: been building Wanderlodges since 1964, most of which are still on the road, wiring fires can be counted on one hand. I'm still looking for the conduit clamps, can't find any.

I went over to what used to be Desert West Coach in Phoenix today. They went out of business in February 2010. According to the few people left there, a new owner took over in May 2010 and the business is now named Divine Coach Care. I saw a few seated coaches there with "Divine Coach Transport" on them, so I assume it may be a small local transport / bus line operation.

Their "inverter tech" wasn't in this week so I'll evaluate whether I'll return there next week.

It's always sad to see these businesses that were once obviously quite successful reduced to a small staff and a bunch of empty, decaying buildings.

I want to thank everyone for the tips and help provided here, I finally got my inverter issues sorted out.

I had John Bata at Divine Coach (formerly Desert West) replace my strange factory fuse arrangement with proper fuse holders. However, replacing the blown fuse didn't fix the problem - leaving the Xantrex inverter as the prime suspect. Divine had no inverters in stock, but after calling around I found some units at Tekris in Gilbert, AZ.

Although they carry Xantrex, I opted to go with Magnum for the replacement, since they are made and supported here in the US. Once the failed Xantex unit was removed, I looked at the other inverter (a Heart Freedom 25) and discovered it was original to my bus. Figuring a 15 year old unit was likely to be approaching the end of its functional life, I had it replaced, as well.

So, I now have 2 new Magnum ME3112 inverters along with new remote panels for them. Magnums also come with battery temperature monitors, included so that should help avoid some issues that could develop with my Lifeline AGM's if they underwent non-temperature compensated charging. The new remotes are great - they have a screen that provides way more status information (including battery, FET and transformer temperatures at the inverter) than the LED display bars on the old inverters.

I highly recommend Brian (who runs the branch) and Vince (the tech) at Tekris Power in Gilbert, AZ. In my opinion, the price for the units and labor was more than fair. Whether you need work done or just want to order inverters and parts, I would strongly suggest you give them a call. I don't know if their main operation in NJ is of the same quality, but I would certainly check them out, as well, if I were on the East Coast.

Hi Bruce,
Did you ever figure out what the problem was? I'm getting no power to my appliances and electrical sockets when using the house batteries. The lights and toilet will work, but no refrigerator, radio, or outlets.

Everything works when connected to shore power or when the generator is running. I have two Xantrex Heart Freedom 25 inverters and a Marathon 5600 emergency management system remote on the dash. I turn the inverter switches off in the bay when powered up and turn the inverters on/off from the remote on the dash.

I've already disconnected the power to both inverters and let them sit for about an hour before reconnecting them to the batteries. No change...

Ant suggestions?

Bruce,

I'm surprised anyone would have sold you modified sine wave inverters. Although your coach came with MSW units, the added cost of a pure or true sine wave inverter today is almost nothing when compared to the MSW version from the same manufacturer.
