Wiring Diagram Msd 8860 Harness can be very useful guide, and wiring diagram msd 8860 harness play an important role in your products. If there is now spark, the coil is at fault. Turn the ignition to the On position. If your engine continues to run even when the ignition is turned Off you are experiencing engine Run-On. Hold the Gray tach output wire to ground for seven seconds. Remember to always use proper connections followed by soldering and seal the connections completely. Playback Tach: If you use a playback tach, be sure to check the high rpm value prior to turning the key to the On position.

Substitute another coil and repeat the test. With that, you can then experiment with the plug gap to obtain the best performance. If you are not running an alternator this is an imperative check. If there is no spark skip to step 6. Each time you pull the wire from ground, a spark should jump from the coil wire to ground. Experience at the races has shown that if your engine is experiencing a miss or hesitation at higher rpm, it is usually not directly ignition. If everything checks positive, use the following procedure to test the ignition for spark.

The dial on the left is for 1,000 rpm increments, on the right is for 100 rpm increments. Page 5 outlines setting the cylinder select. I have purchased several items from American Muscle and plan to buy many more in the near future. Ground the Gray tach output wire. Do not crank the engine. Always securely connect the ground wire to a clean, paint free metal surface. When the key is in the On position, the rev limit will be displayed and may override the tach memory.

The Ignition will deliver full voltage with a supply of 9 - 18 volts. With this function users can be sure of their rev limit settings before each drive. A special rev limit must be selected when connecting to the Power Grid. The Soft Touch produces a load-free rev limit that is within 1% of the selected rpm. As soon as this process is complete the feature will be activated. Make sure the Diode is installed facing the proper direction as shown in Figure 6.

Register a Free 1 month Trial Account. Most probable causes include faulty wiring, a coil or plug wire failure, arcing from the cap or boot plug to ground or spark ionization inside the cap. The trigger wires should be routed separate from the other wires and spark plug wires. When activated, an rpm signal is sent to the tachometer. They are extremely accommodating and a pleasure to deal with in every respect.

If spark is present, the ignition is working properly. Inspect all of the wiring. If there is no spark skip to step 6. This output produces a 12 volt, square wave see page 2. When you find a suitable location to mount the unit, make sure the wires of the ignition reach their connections. The magnetic pickup wires should always be routed separately and should be twisted together to help reduce extraneous interference. Routing: Correct routing of the plug wires is also important to performance.

If 12 volts are not present, find another switched 12 volt source and repeat the test. Also be sure that the program dials can be accessed. The gap of the plugs can be opened in 0. This is a glass woven and silicone coated protective sleeve that you slide over your plug wires. Note: Diodes are used to allow voltage to flow only one way.

The high speed controller can make extremely quick compensations to the output voltage, multiple spark series, timing and rpm limits while maintaining precise timing and accurate rev limiting. If this occurs, bypass the filter. The chart in Figure 4 lists common tachometers and if an Adapter is necessary. This usually only occurs on older vehicles with an external voltage regulator. It is not recommended to mount the unit in an enclosed area such as the glove box.

The holes should be placed between the terminals, at rotor height and face away from the intake. Note: The engine can be running as you make adjustments to the rev limiter function. See the seller's listing for full details. At higher rpm, since there is less time to charge the coil to full capacity, the voltage falls short of reaching maximum energy which results in a loss of power or top end miss. Wires should be routed away from sharp edges and engine heat sources. There should always be a ground strap between the engine and the chassis. For more information on recommended coils, check with our Customer Service Department at 915 855-7123.

To lengthen the wires, use one size bigger gauge wire 12 gauge for the power leads and 16 gauge for the other wires with the proper connections. Setting both rotary dials to '1' will activate a special function explained below. This tool allows you to check your complete ignition system while it is in the car as well as the operation of rpm limits, activated switches and shift lights. The tachometer should sweep to the rpm limit set on the ignition. The problem is that once you have gotten your nifty new product, the wiring diagram msd 8860 harness gets a brief glance, maybe a once over, but it often tends to get discarded or lost with the original packaging. The cap should be clean inside and out especially the terminals and rotor tip. This results in a voltage signal that is too low to accurately trigger the fuel injection.
