Going to get coach

[Gregory OConnor]

Leroy, I guess the sender at the puke tank is more of a on off
switch. you can remove the two wires and test for continuity at
ideal condition??

One other area of issue is the overbuilt cooling system integrity.
the hoses are all top of the line major buck multiply material and
even the puketank is high quality stainless steel. If the radiator
cap is the only place to relieve over heat coolant pressure the line
to the tank and the cap have to do their job when called for. If
the cap wont open and the line is not of a larg enough id (CurtS
coolant filter??) the next week link could be a minor compramised
liner seal. Even the high fail hose to the aircompressor ages to
handel more pressure untill it cracks from an external flex. then
there is the dynamic that while overheating you are puking into the
p tank and sending a signal to the coolant level modual that all is
well with coolant level.

Ross, if I has a $9,000 generator in my boat, there would be no room
for the ores

coolant level sensor show the switch open. If the drawing is for
normal conditions including full water in the puke tank then
presumably the sender closes forming a circuit in abnormal
conditions ie. low coolant.????Then the module sends a prompt to the
DDEC II to go to ramp mode and cut off impulses to 4 of the EUI's.
Presumably, it also disables the cruise enable also. It seems if the
switch is normally open, if circuit wires were shorted or the module
was shorted internally the indication prior to start would be "do
not start" and a stop engine light, but I do not have enough
schematics or books on the DDEC II to figure it out. What do you
think?

someone else understands the thing. I have gotten this far by
studying my master coach prints, the generic systems in the DD
manual, an overall generic DDEC II schematic and talking to Glen
Rogers at BB. He was on the line when my coach was built.

coach. It has 5 wires and is a DDEC system. Ignition hot, ground all
the way to the batteries, (this ground is tied into the ATEC trans
system and the cruise enable also), data wire to the ECM and two
wires to the sensor.

power) then the ground to the module could be disconnected.

DDec computer 12v+power links from the battery to the Ddec and the
post claimed that it was the power to 1/2 the cylinders. Ikinda
think half the power is a wierd way to wire 1/2 a computer and
always wondered why his bus would run on 4 cyls.    since ramp mode
is 4 cylinders, may have been the ground in the battery area (where
the coolant module gets its ground) that when cleaned up( in the
blind search for a fix), finaly kept the bus out of ramp????????

DDEC II into Ramp Mode as all 8v92's with DDEC II were sent out from
BB with this pre programmed. High coolant temp may not have worked
if the water abruptly dumped into the crankcase but one should also
expect high tranny temps in this case also. The sensors on my coach
which can only safely be checked by hooking up a tester on the DDL
are, coolant level, low oil pressure, high water temperature, and
low fuel pressure.I have an optional coolant level module also.
According to BB all should give an alarm if working properly and
initiate Ramp Mode within 15 seconds of an event occurring outside
the pre programmed parameters in the DDEC II. The buzzing when the
key is turned on checks the circuits integrity, not the integrety of
the sensors themselves. I gotta
