Troubleshooting Automotive Ignition Systems

Automobile ignition systems have never been more reliable, but when not, how does one troubleshoot? and is it really an ignition issue? This simple test setup costs only about $1 and may easily be taken for a road test to help isolate mind-blowing intermittent problems. It consists of 2 LEDs and a meter. The standard means of troubleshooting is for a mechanic to change boxes and pass the cost onto the owner even if it does not solve the problem—and some systems have multiple boxes—and it might not even be a box issue. This method will help isolate the problem before making large expenditures. When my car (86 Dodge Aries) developed intermittent problems, I took it to my mechanic. It ran perfectly while he checked it out. His response: “If it ain’t broke, I can’t fix it.” So I kept driving it until it stalled in pouring rain. I then pulled the wire from the coil to the distributor and checked for spark and it was DEAD. While that was useful information, it did not come close to isolating the problem. Eventually, it restarted after healing itself for another week.
