Ignitions 101| 08/14/2016
Since electricity is not something we can physically see, the ignition system of our cars sometimes holds a little mystery or suspicion in its operation. It’s important to realize that electricity, especially in an automotive setting, is not magic. And it’s also important to realize that the ignition is key to your engine’s performance. Your engine’s overall performance is counting on that spark for complete combustion. Once you have a better understanding on how the ignition works and what each component actually does, things will begin to all make sense – and you’ll be able to build the right ignition for your engine. Key goals of the ignition system:
The Coil| 08/14/2016
If there is a single part of the ignition that can holds some mystery to its operation, it is the coil. In a stock ignition system, 12 – 14 volts are delivered to the coil via the positive and negative terminals. Within the wink of an eye, it sends and output of 15,000 volts or higher! But there is no slight-of-hand taking place here – it’s all a carefully crafted lesson in electronics. And one that can be tuned to meet a variety of output requirements.
Magnetic Pickup in the distributor| 10/02/2015
The magnetic pickup in MSD Distributors can also be checked with an Ohm meter to make sure it is within operating specifications. Once again, connect the Ohm meter's leads to the two terminals of the pickup. The resistance should be within 500 - 700 ohms. If the resistance is out of this specification, inspect the condition of the wires leading to the pickup for abrasion, shorting or opens. If the wiring is okay, the pickup is at fault.
MSD Troubleshooting Techniques| 10/02/2015
Troubleshooting typical symptoms that arise during installation.
Import Vehicles| 10/02/2015
If your fuel injected import vehicle fails to start or the tachometer reads erratically, you will need an MSD Tach Adapter PN 8910. If the PN 8910 is installed and you have spark but the vehicle will still not run, you will need a special Tach Adapter. Contact MSD Tech for the correct Adapter.
Modifying AMC oiling for performance| 10/02/2015
An age old hot rodding adage goes something like: “An engine is more than the sum of its parts”. While that oft-repeated saying has been tossed around so much as to be threadbare, that doesn’t make it any less true. Details are key, and are what separate two otherwise identical engines. Many enthusiasts are so focused on choosing parts that they sometimes overlook little things in assembly that will improve their engine’s durability as well as its performance.
Tachometer Operation| 10/02/2015
If your tachometer doesn't read correctly after installing an MSD, you may need a Tach Adapter.
Engine Run On| 10/02/2015
If your engine continues to run even when the ignition is turned Off you are experiencing engine Run-On. This usually only occurs on older vehicles with an external voltage regulator. Because the MSD receives power directly from the battery, it does not require much current to keep the unit energized. If you are experiencing run-on, it is due to a small amount of voltage going through the charging lamp indicator and feeding the small Red wire even if the key is turned off.
