HELP! stuck in Wisc - need wiring diagram for 88-89 DDEC I

[one_dusty_hoot]

Ken & Patti, hate it that you are having problems.

First, I will qualify my knowledge of the 8v92 which
is squat, if a BB, it would rattle in tin bucket.

The warning system can be problematic indicating a
fault that is in fact within it's own circuitry. It,
in your case the DDEC I, be know to shut the engine
down when it senses damage could be done running.

A good friend of mine has an 88 WBPT40 DDEC I and was
worried with similar symptoms many times. His vital
engine signs were good, oil pressure, engine temps,etc,.
With a codes tester a problem would be shown but not
the actual problem. (a generic codes tester)

The Detroit people had stored the DDEC I test equipment
*upstairs* as this was a system that was superceded by
the DDEC II and not used much.

As a side note will ad this. I have a car with a similar
problem. When I take it to the shop, it's working, never
fails to do this. Mechanics tell me there are something
like 57 sensors that could cause the warning light, and,
unless I wanted them to systematically go through replacing
all the sensors, I would have to live with it till a complete
failure occurred. I found the fix, a small piece of electrical
tape over the light on the dash. Still goes on an off today.

The fix required *dragging* that equipment down to do
an evaluation of the problem. When they did, the cause
was readily found, a loose ground. Tighten a screw with
no problem since.

to Antigo Wisc yesterday (Friday) to have the new slide outs
installed in ToWanda's bays when our "Check Engine" light came on and
she cut to half power. All gauges were reading just fine when the
light came on. She restarted for us and we were able to get her over
to River States Truck & Trailer. She ran fine, all gauges reading
normal, no power problems, just the Check Engine Light being on was
the only indication of a "problem."

was the oil temperature sensor. They replaced the sensor but the
Check Engine light remains on. It appears to be a problem with
wiring going to the sensor. River States is trying to track down a
wiring diagram from Detroit for us.
