Newbie - Ignition Control Unit ?
Hello everyone. Allow me to introduce myself. My name is Raffi, and Im trying to help my friend figure out a problem with his car. It is a 1971 Mercedes 250. Immaculate car. He is in the process of completing a restoration, but has ran into a problem. We tracked it down to the Ignition Control Unit. I did some research first on this website for this issue, and someone had said to check all the soldering connections on the board, as that is usually the main cause of the problem.
Upon opening the casing of the unit we noticed had the transistor that is under the dust cover is defective. We wouldnt mind soldering on a new transistor, but we are unable to locate one. We checked all the electronic stores near our town, and checked online also. The only ones we can find were 2 prong transistors. The Mercedes requires a 3-prong.
The ID numbers on the transistor are as follows.
An exact replacement or a subsitute would be great.
We would appreciate all the help. I can post a picture of the exact part if needed. I will also post some pics of the car if anyone desires.
Thank you much.
