    I have an 84 K5 which I have done some extnsive restoration work on. I am having a problem in the steering column and a voltage drain. When the truck is started and in park the voltage reads about 13. When I shift it into R the voltage drops to about 9 or 10. In Overdrive the voltage is also about 9. If I push the shift lever up to the top side of the shift detent and hold it there the voltage rises to the normal 13. The same thing happens in D and 2. My problem is that if I want the car to run at 13 volts I have to keep my hand on the shift lever pushing it towards the insturment cluster. The truck runs fine at the lower voltages aside from the side effects of the lowered voltage like that the lights are very dim, the oil pressure and temperature guages dont read correctly, and the radio cuts out if the voltage drops too low. If anyone has any suggestions as to what to check for it would be greatly appreciated.

    Thanks

    This might sound weird, but check your body grounds. All kinds of weird stuff happens if you don't have a good connection between frame, body, and the negative post of your battery.

    I think there are two +12V sources inside the steering column, turn signals and ww wipers. Sounds like you're going to have to go inside. http://home.t-online.de/home/O_Scholz/steering.html

    Might as well tighten the column and do all other things you can while you're in there. ww wiper switch, key switch, etc.
