Question about 1987 Ford F 250

2 Answers

On my 87 F250 diesel, sometimes when I start it, the voltage indicator doesn't show any volatage. Truck starts fine, but after driving it a little while, the steering column becomes abnormally hot. Any ideas as what to look at?

    Remains negative all the time. I don't see it go positive until I go out to start it the next morning.

    Does the amp meter show a charge after a few minutes or does it remain negative?

Inspect the glow plug module, sounds like it could be sticking/shorting. Have your alternator tested, the diodes could be bad causeing a bad ripple effect.
Good luck..i hope this helps.

If the truck is a diesel, I would look at the EGR valve and the throttle position sensor. The TPS and even the EGR should turn the check engine light on and set a code.
There was also a problem with the turbo boost sensor.

White smoke for a diesel means air in the fuel system. You will have to start at the engine, I start at the line going to the fuel pump. Get some fuel in a can, remove the line to the supply side of the pump and put another line from the can to the pump. If it starts and doesn't smoke , then you have to work your way back to the tank and find the spot that is sucking air. If it doesn't start the I would replace the filter first, check again. There is a possibility that the injector pump is bad, but these don't usually throw white smoke. They just make the engine have very little power or no start.

87 f250 drained brand new battery


I would first have the alternator checked by an auto electrician to ensure it is working correctly and is providing the correct volume of current. It may be faulty and when driving you will be drawing battery power instead of power from the alternator to run the electrics. This will drain the battery.

Alternators do not last forever and if you are still running the original unit it is likely to be on it's last legs and you will need a replacement unit.

Hard Starting in morning


Do mean you have hard time communicating with a scanner at the OBDII connector, if so make sure you power at pin16 at diagnostic connector, also we have seen issue with glowplugs not working properly causing hard start when cold and starts fine after warm-up
You can check for glowplugs operation at initial key-of before cranking by checking for voltage at each glowplug connector with a multimeter.
