What causes loss of spark?

What causes loss of spark?

Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.

How do you test a Mopar coil?

A good/bad test of a coil is to ground the negative side and momentarly touch 12v to the plus side of the coil. If a spark jumps out of the iginition terminal and shock the crap out of you the coil is ‘working’.

How do you test a Mopar ignition control module?

CAUTION:

1. Turn Ignition Switch OFF.
2. Remove wiring plug from the Control Unit (ECM).
3. Ground negative voltmeter lead.
4. Connect voltmeter positive lead to the harness connector cavity No.
5. Turn Ignition Switch to RUN.
6. Verify voltage is within 1 volt of battery voltage with all accessories off.

How do you check a pickup module?

Checking your ignition module is an easy task that requires only the simplest of tools.

1. Remove one plug wire at the spark plug and insert an old spark plug into the end of the plug boot.
2. Check for voltage at the coil positive terminal when the ignition key is on.
3. Locate the ignition module positive (+) wire.

How do you test an ignition pick up coil?

Connect the red (positive) lead of the multimeter to the outer, positive terminal of the ignition coil. Turn the reading dial on the multimeter to ohms to measure resistance of the primary pickup coil. (The Greek letter omega denotes ohms.)

How do you test a MSD magnetic pickup?

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.
