Why is my ignition coil not getting power?
As in the diagram below, most ignition coils share the same fuse and/or relay that feeds the power supply. So, if an individual coil is not getting power, suspect and open or short circuit in the wiring to that coil. The factory wiring diagram will need to be traced for further testing.
How do you get spark from ignition coil?
High voltage is then generated in the coil windings. Voltage transformation produced by the interruption coincides to each spark generated. Older ignition systems used breaker points to interrupt the circuit, while more modern systems “sense” the need for spark by means of a hall-effect switch or crankshaft position sensor.
What should the resistance be on the ignition coil?
This tests the coil primary circuit; typical readings should be 0.4 to 2 ohms. Consult the manufacturer’s repair information for the exact specifications. Next, check the secondary circuit resistance. Do this by attaching one meter lead to the B+ terminal on the coil and the other to the coil output tower.
When does the PCM set the ignition coil code?
Since the secondary winding contains many more turns of wire, output voltage is increased to thousands of volts. This is enough to fire the spark plugs. The PCM sets an ignition coil control circuit code P0351-P0358 when it detects a problem with the ignition coil circuit.
Is there an electronic ignition for The KZ400?
After a longtime search for an electronic ignition for my 400 I’ve met with success. I’ve wanted to replace the points for years but wasn’t able to find anything worthwhile really.
What happens when there is no spark from the ignition coil?
1 Power. Two positions of the ignition switch provide power to the positive primary post of the ignition coil. 2 Signal. With no external signal to the coil negative primary post, voltage would travel through the ignition coil windings without inducing any secondary spark. 3 Flow. 4 Open Circuits.
How does the ignition coil work in a car?
In the “start” position, the switch energizes the starter motor, and full battery voltage is directed to the coil while the engine cranks. Once the engine starts, the switch is released to the “run” position. The coil still receives voltage, but the amount may be reduced by a resistor in the “run” circuit.
What should the resistance of an ignition coil be?
Switch the meter’s resistance range to the 20K-ohm setting and attach the negative (black) meter lead to the center terminal of the coil. The reading here should be 11.00 or better, with 13.49 being about normal. If your coil reads under 11.00, then chances are pretty good that this is the reason you’re not getting any spark or a very weak one.
