You only need two tools 1) WD-40 and 2) Duct Tape:

 

If it doesn't move and should, use the WD-40;

 

if it shouldn't move and does, use the duct tape.

 

 


 

 

Allison High Efficiency Filters

 

Allison Transmission has introduced a line of high capacity filters that can, if used along with an Allison approved synthetic automatic transmission fluid, allow owners to extend their fluid change intervals. (Click here to go to Allison's website for a list of currently Allison Approved TES 295 automatic transmission fluids.) 

 

Transmissions built with the new filters do not require an initial Main Filter change at 5,000 miles/200 hours.

 

The new filters were introduced over the last couple of years and there is no clear manufacturing date to tell if your Allison Transmission has the new high capacity filters.  If you have a 3000 series transmission, serial number 6510670912 or higher, or a 4000 series transmission, serial number, 6610205144 or higher, then you should have the new filters.  A general rule would be if your FCCC chassis was built after September 1, 2006 then you have the new high capacity filters installed.

Rear Brake Lights not working on your coach?

 
[Here's some recent info via the FCOC Yahoo discussion group - ]

I had hazards, turn signals and tail lights, but no brake bar, no brake lights,

no engine brake light.


The problem was diagnosed by the F-liner help desk as being bad diodes. 

The problem was neither Fliner nor Winny could tell me where
they were located.  Well, we found them.


So, for those of you who wanted the info, the suspect diodes are
located at the base of the steering column, in their own harness which
is about 9" long, 1/2" wide with spade connector clips on each end.
The good folks at Sterling Truck in Tallahassee found them and they
were cooked!  Ordered replacement o-night from Fliner, snapped in the
new 9" segment and Voila!  Brake lights again!  Fliner picked up the tab

for both parts and labor.
So there it is, FWIW.
Paul

 

Editor's note - According to FCCC tech support, this problem was mostly 1997 - 1998 model chassis. The original design used only one diode that sometimes got overloaded and blew out. The design changed in 1998 and a 2nd diode was added making this problem a pretty rare occurrence.

Looking for fuses for your TOW plug wiring?

Here's some recent info via the FCOC Yahoo discussion group -

On our 04 Horizon (sister coach) those fuses and fuses for the tow plug are
located on the drivers side of the coach behind the electric shore plug
compartment.  In our coach there are 4 boxes full of fuses behind the dash
AC evaporator coil (below the engine air intake)
.  To open that compartment
you need to remove a couple screws on the bottom of the door and a couple on
the side where the electric compartment door opens (the door swings up). 

It cost me an hour of a technician's time to find those fuses.  I hope this helps.

[Note your exact location may vary depending on where the coach builder located them]

New Bedroom slide-out

got your

Satellite Remote 'snookered'?

 

Our new bedroom slider is great...adds so much more room. However, my DBS satellite remote control is Infrared (IR) and doesn't go around corners very well. Our bed is at right angles and our TV center is also side-mounted in the living area which means my satellite remote must traverse TWO right angle turns. . . so, I can not control the satellite channels from the bedroom!?

 

Here is a nifty DBS satellite accessory called a Remote Control Signal Sender.  This device places a remote IR/RF (Radio) sensor near you and a complimentary sensor RF/IR near your satellite receiver. Your satellite remote control sends it's IR signal to the new sensor in the bedroom which converts the output to Radio waves (RF) which is transmitted to the other sensor up front near your satellite receiver. That sensor or base unit, converts the RF back to IR which is picked up by your satellite receiver...bingo works like a champ.

DBS Satellite Remote Control Signal Sender

 

Best news of all. . .found this unit at Wal-Mart on sale for only $35!  After searching the internet...there are several similar systems out there, but many were $80 to $150 dollars. This particular model may have been a discontinued item and may not be available anymore. However, the regular price was only $40 and if discontinued, there should be similar units on the shelf at Wal-Mart, Best Buy or Circuit City.

 

There was no programming to do, no model #s to enter. . .it was truly 'plug 'n play'.

New C93 Light Bulbs. . .

Have you encountered one of these new light bulbs...maybe your porch light burned out and you went to change it. A CEF 93...what?  Looks like a regular 1146 or 1156 bulb...but is says CEF 93 and made in China. I tried to find this bulb at auto parts stores, Wal-Mart...no one carried this bulb!? Having been 'burned' in years past by substituting an 1156 for a 1141 and melting my porch light fixture...I was a little cautious about getting the right bulb. The fixture had stamped on the back plate, substitute was a 1003 bulb. So I tried the smaller 1003LL which I hoped would not melt things. It worked ok but seemed to burn out faster than the C93. Well I finally made time to research light bulbs and compare specs. Here is the result.

 

Bulb Amps Light Output MSCP Energy Used Watts Life Avg. Hours Watts < over C93 Remarks
C93 1.04 15 13.3W 700   New bulb used in outside RV lites
1003LL 0.94 15 12W 400   RV recommended replacement for C93
1093 1.19 15 15.2W 1,000 7% Good replacement only 1.9W more & much longer life
1142 1.44 21 18.4W 1,000 38% Old standby bulb easy to find at any auto parts store
1141 1.44 21 18.4W 1,000 38% Old standby bulb easy to find at any auto parts store
1156 2.1 32 26.9W 1,200 100% Old standby bulb but too hot - could melt your fixture

 

Yes, the 1003 would not melt the fixture, but look at it's avg. life...only 400 hours! The data reveals a much better choice, the 1093 and I had thought they are available at most stores that sell auto parts. However, recent experience has shown that the 1093 is also hard to find. So, I thought the old regular 1141 and 1142 are brighter and probably will work fine in most RV light fixtures - WRONG!  Been using an 1141 and it too MELTED part of the top of the snap in lens...not bad, but just enough that it will allow rain to enter the fixture!  That will break the bulb if you have your porch light turned on in a rain storm. . . so, back to the easy to find 1003 (but short lived), or trying to find the elusive 93 or 1093 bulbs.  The RV industry doesn't make it easy...I was just at Camping World today, NO C93s, no 1003LL (LongLife), just regular 1003s.

 

BTW be careful with the 1156 or 1157...they are too hot for most RV light fixtures, they are designed for tail light fixtures and they WILL MELT your plastic light fixture!

 

Hope this helps.
