Fuel on the ground under engine!!??

[Busted Knuckle]

Does this apply to DDECs?   I was under the impression (however mistaken it may be) that the override switch would keep the bus running for several minutes as long as it was held in the on position.  Is wrong?  May be that the shutdown system on an MUI operates differently?

JR you are correct with the DDEC unit you should be able to just hold the overide button in and get it off the road, if my memory serves me right it gives you like 30-60 seconds. Then it dies & you'll have to turn it off and restart it while holding the overide again! (but it's been a long time since I've dealt with it and maybe only partially right about this! (especially with a NJT as they did some different things on their own!  BK

Hello all.

I might suggest a busnut with an older mechanical motor should get rid of the auto shut down system.

Here's why:

The shut down system was there to protect the coach from uncaring employees. If the motor shut itself off, the driver couldn't keep driving it.

Busnuts, since we pay the bills, won't keep driving it until it seizes, and we would prefer to choose the place to pull off and park, rather than the coach choosing for us.

And try to hold your starter button in against that spring to bypass the shut down and steer.....

happy coaching!

Well, to each their own.  Personally, I hooked mine back up and made sure it's working properly.

Why?

Well, I don't have $10K to spend on a new engine, and if for some reason I miss the temp rise due to loss of water or otherwise, I'd prefer not to have to say, "well, I'll be more careful next time."

If I have to hold down the button and steer to get to a safe place to figure out what's happening, well, so be it.

BK, you got it right....hold the switch under the bomber door and you have 60 seconds to start the bus and get off the railroad tracks.   Then the ignition switch must be turned off and on to reset the override and  go another 60 seconds. 
Unless one has alarmastats or something to announce a low oil or overheat issue, the shutdown feature is probably best maintained...IMHO.  A major fault with early MCIs is the crap dash with the guages buried in holes.  No one can read the guages without gettiing forward and looking down into the holes the guages are residing (hidey holes) in. 
Even Terri, who's generally a tightwad when it comes to the bus, wants a new dash.  That reminds me, gotta call Luke and get some of those dash light bulbs....both center guages are quite dark at night.  The dash is a fine reason to have a 102A or later.  They have nice, easy to read dashes. 
Regarding the starter limit fuel pressure sensor...since the starter isn't necessary for operation of the emergency override with a DDEC, no replacement is necessary.   On DDEC units, this is all a function of the ECM.   MUIs have a Robertshaw control sytem??  A sort of mechanical gizmo that will shutdown on overheat, low oil, or hot oil.   
Thanks, JR

JR,
  Remind me to show you the R&M dash in our MC-8 when you get to Arcadia.  When we rewired our bus, I did away with the auto shutdown. HOWEVER, each alarm system has a flashing red LED in the dash and it's own audible alarm (Each alarm is a different sound (ie. Low Air=buzzer, Hot Engine=constant high pitched tone, Low Oil=beeper). The audible alarms are only on the situations that require immediate action. Alarms that do not require immediate action such as No Charge, Low Tag, and Low Fuel have flashing LEDs only (I can still drive with these conditions and don't want to hear an alarm sound). Because Hot Engine and Low Fuel alarm senders only function when a hot engine or low fuel condition exist, I added a test switch on the left panel to check operation of these each time the engine is started. Just our way, YMMV  Jack

Thanks Jack,  I saw your dash at T'ville...great work.  All that wiring is beyond my simple skills....plus the DDEC cannot be easily defeated, nor do I wish to defeat the the 3 shutdown codes.  So I reckon I'll stick with the factory settings.   
Your dash is an item that we could easily deal with...the only problem is my steering column is  flat and will not fit into the R&M  dash that's designed for an MCI.  Wonder what factory made dash would be available without the notch for the OEM steering column?  May end up building a dash...have to see what I can find.
See you soon, JR
