Hello and welcome back to our mini-series on automotive tips and how to guides for the midpoint Joe. This is a great series of articles if you are new to auto mechanics or maybe you just want to understand a microscopic more about what all goes on under the hood of your car. We've spent a lot of time on tools, but in today's article I'm going to go over your car's distributor. It should be noted that more and more modern car's are switching to distributorless ignition systems which we will be face in a later article.
The function and purpose of the jobber is pretty direct. It takes the spark that is generated by your car's ignition coil and distributes it out to the individual ignition wires at the allowable time to generate combustion inside the combustion accommodation of each cylinder. Roughly all distributor's use a jobber cap, and either a rotor or a set breaker points and condenser to facilitate the distribution of spark energy. As the rotor in the case of most modern cars swings across it's circular arc, the tip of it makes electrical sense with the jobber cap to send the electrical current to the ignition wire and later the spark plug. A points ideas works in much the same way, but a points jobber ideas has some very considerable drawbacks and hence forth aren't used in modern cars, and even in cars that have been built over the past 30 years. Any problems with sense or oxidation on either of the rotor or jobber will cause random misfire issues and are commonly the cause of random misfires. Sometimes random misfires can be caused by other problems such as a bad jobber operate module or cracked coil, but 9 out of 10 times, it's commonly just the cap or the rotor.
