Subject: Trucks owners in Baltimore?
Just wondering if there are any list members in Baltimore,Maryland. It
seems as if I am the only one around!!! E-mail me if your in the area.

The Power Control Module has many sensors that feed into it. I know in the
case of an automatic, it knows the torque output from the engine, throttle
position, vehicle speed, transmission fluid temp, turbine shaft speed among
other things about the drivetrain. IMO, the increased demands put on the
engine causes one or more of the sensors to indicate to the PCM that the
truck is laboring, and the computer can't correct enough to allow the truck
to operate "normally", what the PCM considers right using it's set
It might be a good idea to take it to a dealer or a shop that can read the
codes to see it anything has set an error code within the computer before
throwing parts at it. According to the manuals for my '97, the check
engine light is the one of the lights that is used to flash codes to the
technician when he is troubleshooting the vehicle. I am unsure if there is
a way to use the check engine light only to find out error codes, I think
you use it with the STAR tester that the dealer has.
Installing the larger tires could have confused the computer. I have heard
of times when the computer can get confused due to many things, and the
truck can recognize vehicle speed using the transmission as it's source.
It uses that with other readings to determine air/fuel mixture and shifting
patterns and other things.

Might be related to the problem showing the check engine light. Sounds
like the switch itself is OK, like it's operating a relay in the dash. All
the powertrain components are interconnected, so I guess one problem could
cause many things to act funny.
Let me know if there's anything I might be able to check in the shop
manuals (they're the Ford Technical Service Support ones from Helms) that
might help. You can email me personally if you want.

From: Steve Field
Subject: F350 Deisel, 2 batteries, again
The current question involves the device that hooks from lighter-socket
to lighter-socket and charges the target car.
The source vehicle is the F350/Deisel - The idea is to be able to charge=
some other car. One would leave the truck idling and the charge takes
about 15-30 minutes.
The questions are: How safe is this? For a deisel? Anyone have
first-hand knowledge of using such a device? Are there any phone numbers=
at Ford for technical info in this area?

Subject: Re: Dual Tanks and Oil Pressure Gauge
David, I do not know which year or model of truck you have or if it is a
single owner or multi owner, but on the 1989 F-150's- 350's/Bronco's and
f-Super Duty trucks the oil pressure gauge was not a gauge on all the
trucks. Ford used both a oil pressure switch for indicator lights in the
instrument cluster or combined the switch with a 20 ohm resistor mounted on
the flexible circuit board in the instrument cluster to turn the gauge into
a indicator. The switch was designed to close at between 4.5 and 7.5 PSI.
This will caused the gauge to read about the middle of the scale( that's
what the 20 ohm resistor is far.
You said that the wire to the sender or switch was cut and a diode and
resistor where there. The wire to the sender or switch should got direct
the instrument cluster because the cluster supplies battery voltage to the
sender or switch. The only system that uses a diode and resistor is the
air conditioner. The diode and resistor go across the compressor clutch
coil so that when the compressor is turned off the fly back voltage
generated by the coil will not cause a problem with rest of the electrical
system. If this is the way the truck is wired you have wiring problems and
they need to be fixed before you go any further.
An easy way to tell which type of oil pressure gauge you have is remove the
wire from the switch or sender and ground it for no more than fifteen
seconds with the ignition switch in run position, do not start the truck.
If you have a sender then the gauge will move all the way to the high end,
if it is a switch it will move about to the middle. Now, since your gauge
is not working all that well this may not work for you. If you have a volt
meter set the meter to a scale that you can read 15 volts on. Connect the
negative lead to the block and the positive lead to the wire that connects
to the sender. You should read just a little below battery voltage. This
will tell you if voltage is getting down to the sender or switch form the
instrument cluster. If you do not have any voltage then the sender or
switch can not cause the gauge to work.
While you have the wire at the sender or switch disconnected start the
truck and using an ohm meter positive lead to the sender or switch and the
negative lead to the block check what the resistance is. If you have the
switch then the resistance should be zero or close to it. If it is open or
greater then 73 ohms the sender or switch is bad and needs replacing. The
sender should read about 27 ohms or less with the engine running if it is ok.
If you have determined that the sender or switch is ok and the wiring is ok
then you will have to remove the instrument cluster and clean the contacts
that the gauge fits in and make sure that the contacts for the gauge or
making good contact with the flexible circuit in the instrument cluster.
I hope this has helped you.

millimters to inches... (with another hundred for the percent calc...)
so, really multiply by .75, then divide by 25.4 (mm to inches)]

Here is what the numbers on metric tires mean. 235/85 R 16 E
235 is the width in mm. 85 is the aspect ratio, (the sidewall height given
as a percentage of the width) R is speed rating (I think....) 16 is rim
diameter and E is load rating. To find the diameter of a metric tire take
235 by 85% and divide that by 25.4 to get inches, multiply by 2 and then....To access the rest of this feature you must be a logged in Registered User
