If you have an Ohm meter you will want to measure the resistance (ohms) of the Primary and Secondary sides of the coil pack and compare your readings to the Specifications for the vehicle.
You test an ignition coil by checking the resistance with an ohm meter. The resistance values should be something like, Primary winding .3 to 1 ohms, Secondary winding 8,000 to 11,500 ohms.
The CDI for this motorcycle has the code number: 31600-MV4-010. Other information from the manual: Ignition coil resistance, primary coil: 2.6-3.2 Ohm. Secondary coil with high tension lead: 21-29 Ohm, without high tension lead: 13-17 Ohm. Pulse generator coil resistance: 315-385 Ohm.
You can check the ignition module (coil) with a digital volt/ohm meter for a start. Check the primary and secondary circuits resistance and go from there. You can also check the spark plug wires resistance with the same meter.
you cant you can test it with an ohm meter if it reads 000 theres no resistance and its bad if it reads an open its bad you want around a couple hundred ohms
ohm it.
To test primary and secondary resistance in a transformer, you can use a digital multimeter. For primary resistance, disconnect the transformer from the circuit, set the multimeter to the resistance (ohm) setting, and measure across the primary winding terminals. For secondary resistance, perform the same procedure across the secondary winding terminals. Ensure the transformer is completely de-energized and isolated from any power source before testing.
Test the resistance with an ohm meter.
get a volt meter. turn it on. put one end on the +. the other end on the -. if you get a number greater than 12 with the car running then your golden.
in primary side 400KV SYSTEM = >400 M OHM 200KV SYSTEM = >200 M OHN in secondary side <1 M OHM
To check an ignition coil with an ohmmeter, first disconnect the coil from the vehicle’s electrical system. Set the ohmmeter to the resistance (ohm) setting, then measure the resistance between the primary terminals of the coil; it should typically be between 0.5 to 2 ohms. Next, measure the resistance between the secondary terminal and one of the primary terminals, which should be in the range of several thousand ohms (often 6,000 to 15,000 ohms). If the readings are outside these ranges, the coil may be faulty and should be replaced.
The Bentley manual says to pull the plug wires and hold them toward ground while someone cranks the car with the key to see if they spark. I really don't like that idea. My way of doing it is to put my timing light on the number one wire ( it has an inductive sensor ) and have someone crank the car and see if the strobe flashes or not. You can test each wire that way. You can test the spark plub wires with an ohm meter to make sure they have little to no resistance. You can test your coil with an ohm meter as well. Disconect the battery and the coil first. The primary resistance ( between the small + stud and small - stud ) should be .8 ohms. The secondary resistance ( between large center plug where coil wire is and the small - stud ) should be 5000 ( 5K ) ohms.
