  Vibration witchhunt

I picked up 512 at Miami. Marc was nice enough to deliver it there because I wanted Newell to install a rear sway bar. First so all super thanks to Tuga for taking such great care of the coach. Thanks Marc for babysitting it till I had the chance to buy it It was even nicer thn what I remembered. Rhonda is very happy.

In addition the sway bar I asked Newell to put new tires on the rear. Yeah I know, advantage program would have been far cheaper but my local Michelin truck guy employs gorillas and I didn't like the way they handled the rims last time I used them. Plus I was looking at 800 miles of snowy weather and I wanted the best shoes I could have . Other than the normall Newell pace everything is great. I was able to take advantage of being over the pit to get a real good look under and install my toad brake line.

All is well until we hit the interstate in Joplin Hmmm. A low freq vibration that starts at 62 and gets stronger until about 72. This won't do for Mr OCD. So we turn around and head back. Test drive with techs confirms vibration. There is much discussion and theorizing about tires or sway bar being the culprit. Next morning sway bar is removed and test drive is repeated. The vibration is still there. That's kinda good because the sway bar makes a huge difference in the handling. Ok we check runout on the tires and one is out of spec. A deflate, spin 180, and reflate brings it in spec . We are really pushing the weather to get back home so we leave for the second time. Hit the slab in Joplin and no difference Stopped in Springfield and had tires spin balanced. No difference. Those of you who know my legendary patience are crying laughing right now. Stopped and pumped universal joints full of grease and it seemed to get a little better. I could feel a little slop in one of them just a tiny bit maybe a couple of thou. Stopped in St. Louis at Inland truck parts. A drive train specialist. Cept I picked the only shop that did not have a service bay. Oh yeah it's now sleeting and snowing at 25 degrees. They did loan me some specialized tools to get the drive shaft out. Three hours in the snow under the coach later I have it out. One bad diff, runout out of spec and corrected, and a spin balance gets me ready for the reinstall. 30 minutes tops! It's now fixed. Woo hoo! My apologies to the whole crew at Newell for putting them through the paces on the problem solving effort. They were real troopers. The winners prize goes to Pete who correctly Indentified it as drivetrain. So if you have a low frequency rumble / vibration at highway speeds it may be worth looking at the driveshaft especially if the frequency is 9.3 hz at 65 mph. Not that I used some high powered vibration phone app to find the root cause.

All the vibrating and driving has me reall tuned into the difference in road feel between 512 and 390. My theory is the two coaches have different resonance frequencies because of the difference in wheelbase and slides. Although the drive shaft fix cured the constant vibration , now that I am tuned to that frequency I. Oit e road imperfections cause the same resonance. It is a muc different resonance than 390

Suzy & I have developed a conflict with the NASCAR Talladega race. We have two tickets to three days of racing and a campsite in the Family campground. The campground opens on Tuesday April 29th. Racing is May 2nd, 3rd & 4th. Our seat tickets are just three rows from the top of OV Tower--you can see the whole track. Package includes the camping spot for 6 days, 2 tickets for Fridays, Sat & Sunday. We will sell them for 1/2 price. That would be $215.00 If interested email me.

  blowing start fuse

When activating the start switch on the generator it immediately blows the 'start fuse', it's the 15 amp slow blow. Engine never even turns over.

It's a 12kw Kohler w/the 4 cy Perkins, if anyone has a wiring diagram - or has had a similar issue that will get me started the correct direction.

  Swipe & Save card

I guess Flying J/Pilot has redone their RV program. The old RV Preferred customer program has been or is being dropped. It has been replaced with a "swipe & save" card that is issued through the Good Sam Club. Has any one used the new card? Do we still have "pump start" so you don't have to go to the cashier prior to fueling?

For any of you with Cesana showers and that is most of you, they are out of business completely now, but the molds for all parts were purchased by Luxury Marketing who has previously sold parts in the USA for them. I bought a roller for my shower from Liberty Coach a month ago and unfortunately it was the last in stock for $49.90. I do want a spare as you never know and asked Newell today how much and Chuck said "I wasn't going to like it"... $190. each, but if you call Luxury Marketing direct they want $225 each.... Huh

When one cuts the pre-heat switch on, is there a way to check to be sure it is working?

  Ammeter problem

Posted by: folivier

The ammeter on my dash doesn't work properly. With the engine running it usually shows a discharge anywhere from 100-200 amps. The voltmeter is showing 13+ volts so I know the alternator is charging. I've even used my clamp-on ammeter and it is charging.
So I'm assuming the gauge is bad. It's a VDO 0-250 ammeter. Looks like it might be a type b which has an external shunt. No idea where the shunt is located, any ideas?
The gauge has 2 red wires and a brown and orange. I found a VDO document which shows this type but has a + and - wire with 2 sense wires. So not sure if this is the right one or not.
Suggestions?

As I get closer to getting a coach . I may already have a stacker trailer lined up.. Looking at different options for it.. I'm looking at something called a trailer toad.. Would keep all the weight of the trailer off the coach and would allow me to tow with my sequoia. But there is also something called idrive which actually brings the trailer to the tow vehicle.. While I would like to have both only one may be financially doable.. If I get the trailer toad I can actually move it to he stacker with an atv negating the need for the idrive... If any of you smart people would look at both and give me your opinion I would appreciate it.

If y'all ever get bored on I-40 and you are near Amarillo, TX be sure to drop down a few miles and see the second largest canyon in the U.S.
Good campground (a TX state park) and the scenery is spectacular.
Hiking and biking trails and you can even rent horses. The canyon itself is about 800' deep and the spectacular views break up the monotony of the Texas panhandle. For more details and info:
