Golly DArn Cruise...Do me a favor...
Can someone with a 80s model (I have 87 300D turbo) check the green wire w/yellow stripe - this is wire that sends signal from the speed sensor behind the cluster to cruise control. Check it for AC voltage as you are driving and tell me what it reads...
Mine reads steady 4.8v DC and varies by milliamps on AC, but overall seems to fluctuate all over the place on AC. I cant get ANY cruise amp to work, thinking its my speed sensor. Thanks Paul

My speed sensor produces an AC voltage of 5-6 volts - the amplitude is pretty much constant but the frequency changes based upon the speed of the car. The frequency of the AC signal is roughly the same as the speed of the car in kilometer per hour. At 60 MPH the frequency should be somewhere around 100 hz.
This data is for a 91 300D 2.5 turbo but I think it's pretty much the same cruise control system used in your car. Last edited by TimFreeh; 01-06-2006 at 08:15 AM. |

I'll tell you what. I have a Haynes Manual, a factory manual and a good electronics understanding. If you will remove the implication of taking the Lords name in vain from the title of your post, I will do everything I can, short of driving to Atlanta to help you troubleshoot your cruise control problem.
Good luck and have a great day, |
