Modifying AMC oiling for performance and long life

All American Oiling Modifying the AMC oiling system for performance and long lifeAn 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

No 12v present at Coil+

One common question in regards to MSD Ignition controls is “Why isn’t 12V power on the orange (COIL +) wire?”
The main reason 12V won’t be present at coil + is because your MSD ignition is a Capacitive Discharge Ignition...

Timing Fluctuations

 Timing Fluctuations If your timing seems to be jumping all over the place, check the following items What kind of timing light are you using? Many lights have trouble reading the MSD's capacitive discharge multiple sparks. Dial back timing lights

Magnetic Pickup in the Distributor 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
Spark Plug Wires

Spark Plug Wires If you suspect a spark plug wire to be open causing poor performance, check the resistance of each wire. By checking the resistance of each wire you will determine two things That there is continuity (not open)

Tachometer Operation

 Tachometer Operation If your tachometer doesn't read correctly after installing an MSD, you may need a Tach Adapter. On GM vehicles, first remove the tach filter. There are two MSD Tach Adapters. Contact MSD Tech with the manufacturer of your

Import Vehicles

Import Vehicles 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

Engine Run On

  Engine Run-On 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 energ

Checking The MSD Ignition For Spark

Checking The MSD Ignition For Spark The following test will determine if your MSD is producing a spark. (image) White Wire Trigger If you are using the White wire (points or electronic amplifier) of the MSD to trigger the ignition,
