I have a 2006 Beaver Marquis with a C-13 engine. Yesterday driving east on I-10 running about 68mph and the engine just stops running. slows down to about 40mph starts up and it runs for another hour or so and does the same thing. anyone have this happen? Also I am scheduled to have engine serviced and was wondering if the cat dealer will be able to see any codes that might give a clue. All help apprcicated. The Forum is a great tool. Thanks to all who support it.

Bobby,
Had the exact same thing happen to my coach, did it a few times and then just got worse. Had Cat dump the ECM no codes. When it finally got real bad I figured out that it was the Intellitec Start control board #1 in the rear run box, its the board with the switches on it for the rear start. Bought one from Northwest Rv supply for $75 plus $30 for two day shipping. The board number is 73-00825 it is real easy to install, just be very careful with the hot wires in the rear run box, there is a hot wire hooked to the board that supplies power the the rest of the cards in the rear run box.

Bobby,
If you lose all dash gauges and anything else powered by key on 12v your ignition solenoid may be failing intermittently.

Bobby, engine shut down while driving. There is a Cat bulletin on your Key switch that
wil shut down engine. Will pinpoint correct code tomorrow when I get back home from
Phoenix and will put information on Ask Dave technical site. Dave Atherton Retired Cat Mechanic

Bobby, looking into your problem but will need engine serial number. There are several
reasons that could be causing your problem. Mentioned bulletin on key switch, wiring as
Lee indicated. Atmosphere pressure sensor that is shutting engine down than restart of
which is very possible. Cannot go any further untill I have correct engine S/N.

If this was happening with my car, the first thing I would check would be the fuel filter. It's a classic set of symptoms for a clogged filter. Could this also be true of a C13?

Dave my engine is a 2005 Serial Number KCB34949. Will have a filters changed within the next 2 weeks.
Thanks for all the help.

Bobby, engine shut down than restart. Looking into problem shutting down and restart, you
have what is called a event code. ( problem happens than will go away and runs fine ). Cat
ET sometimes will pick up logged event code and many times will not. Which in most cases
sensor problem or dirty connection or frayed wire grounding. First looking at Key Switch event
code 43-02 Cat bulletin interment shut down ( power ). Possible many keys hanging on key
ring. Atmosphere pressure sensor, fuel pressure temperature sensor, fuel manifold return fuel
check valve. If Cat ET picks up on event code and occurs high count, check connections at
Sensor involved. This is information can be helpful if you stop at Cat Service and cannot find
anything wrong. Dave Atherton Retired Cat Mechanic

After letting coach sit for 24 hrs. I was going to back into my shed. Turned key on and nothing, did this 4 times and then everything came to life, started engine and everything was normal. Have a startinig selonid ordered will receive tomorrow. It has never been changed so hope this is the problem. Thanks for all the help.

Bobby,,The next time it will not start or stops running don't turn the key off don't do a thing except set the brakes. Go to the rear run box and open it up and see if all is lite up. If nothing is lite up try switching the rear start switch to the rear and back to the front. If all comes to life all lights on and coach will start I would almost bet money it is the PCB #1 Start Run board. You can also push and pull on the board to see it the system will light up.
I would not think it would be the starter solenoid, if the rear run boards are not lite up it will not start or run. It is probably one of the relays on the #1 board.

Thanks for the info. My 06 Marquis seems to be diffrent in the run box. the only board in the box is 73-00839. Also do not have a rear engine start?? Thanks again

Bobby,
Just clarifying; you mentioned a new starting solenoid. The starter solenoid would not cause the engine to quit running as it's purpose is to supply battery voltage to the starter only when the key is in the start position. The ignition solenoid will cause the engine to quit when running if it opens. From what you posted, it sounds like it may be you culprit.

Steve thanks for the info. Anoter question. I purchased new solonoid and it does not work. Hooked old one up and all is well. What am I missing. Took pics and made sure everything hooked up same. Took old one to parts house when ordered new one. Go figure ???

Bobby,
Be sure you didn't get some wires crossed. Smaller gauge wires should be on the small posts and large gauge on the large posts. Also make sure that the diode is hooked up correctly with the band in the same direction as on the original unit.
With key on you should have 12v on one of the small terminals and ground on the other. The 2 large terminals should both have 12v on them. With key off only one large terminal should have 12v and neither of the small terminals should have any voltage.

Well that figures, that they would build them completely different. Same year almost the same coach go figure.
