Ron,
I have a 91. Let the forum know what you find out. Anyone with a DDEC2
should have an interest

Engine & Tranny problems 2 - ronmarabito2002 - 04-23-2007 15:22
I had to pull into Stewart & Stevenson in Albuquerque with engine
power problems and shift problems. It all started after we left
Dallas yesterday. I had a sudden 170 amps and 10 volts, followed by
total loss of 12 v power to instruments, radio, etc... By the time I
was off the road, the power was back. I then noticed a lack of power.
Pulled some minor grades of 2 or 3% with a drop in speed to 50 mph at
full throttle.
Nursed the unit in to Albuqerque this morning. Had a fuel gage
intermittent that went from normal to full peg on full. When making a
hard left turn, transmission check light would flash and beep.
S & S did a power check and found at full throttle, engine could only
make 1900 rpm. When backed off, the rpm went up to 2200. Just the
opposite of normal. They are very suspect of the DDEC2 at this point,
but are trying to rule out everything else first. Changed air filter,
they were started on a fuel system check when I left for dinner. I
had checked all the connectors this morning and they were fine. Could
not trouble shoot because I have no diagram of those circuits.
I know the grounds on the alternators and engine to chassis are fine.
Not sure about any others, but they are checking them.
I'm convinced that whatever caused that electrical anomoly yesterday,
damaged the ECM and it will probably have to be replaced. $$$$
Let you know more tomorrow.

Ron, Often overlooked by class 8 repair shops are the high amp high
discharge /recharge inverter drawn powersource on a motorhome. The
uncommon factors sometimes reveal possible conclusions. I would pull
all 11 batteries (disconnect) and install one proven battery at the
engine start bank to continue the test. The Carvers had wierd
problems that proved to be bad batteries. I hope it is somthing
easily correctable.

Ron, agree with Greg and would want to find the problem BEFORE a replacement
the ECM is replaced. To pull that kind of heavy current there is a problem
on one of the DC busses. If my memory is correct you recently did some
alternator work. If so start there, check each alternator output
independently, if they are good go around the coach and check all DC items
especially chargers, inverters, connection between the generator 12vdc and
the main bus. Inspect as much as possible. I would expect to see or
smell something.

Well,
I had alot of guage problems, I found that I had alternator problems, when I
replaced both alternators those problems ceased. I have DDEC1 the Alternator
problem did not cause any problems with them. What kind of error codes are you
getting?

I'll bring this up this morning at the shop. The house batteries need
to be checked because they were installed in 98. Top notch gel cells
often go this far, but could be a problem.

Good advice. I wish I was at home to save the cost of the high labor
in the shop.

Engine & Tranny problems 2 - ronmarabito2002 - 04-24-2007 02:24
Had three error codes. 16, 44, and 52 52 was a ECM failure, one has
a high coolant temp and can't remember off hand the other since I'm
not currently at the coach. Both alternators were completely
re-built, so I doubt the problem is there.. Right now, with the high
amp pull and low voltage, I am more suspicious of the batteries.

Engine & Tranny problems 2 - Troy Tikalsky - 04-24-2007 03:00
When troubleshooting problems I always look at the last changes made. You
mentioned the alternators were recently rebuilt, how many hours use since the
rebuild? Since the problem you are having is voltage related I would check the
alternators first and remove them from the equation. Are the alternators
required for the motor to run or will the batteries provide enough power for a
short test?

Engine & Tranny problems 2 - ronmarabito2002 - 04-24-2007 03:11
Just talked to the shop. Nothing on the electrical at this point, but
they found low fuel pressure, changed filters. I had asked them to
change the air filter anyway, because it was needing it.
They found a hole in one of the turbo boost pipes and repaired it.
That alone could have caused some of the power loss. It says nothing
about the crazy throttle response where at full throttle, we only got
1900 rpm and when backed off, we got the full 2200 rpm.
They are getting ready to go do a new throttle response test and power
test. I will talk with the manager shortly to see about having the
batteries isolated and tested.
More info a little later. I will not have internet in a little while,
so I may have to update you when I can find service.
