How do you test a Nissan coil with a multimeter?
Place one lead from the multi meter on the negative post or terminal of the coil. Place the second lead on the positive post or terminal and note the reading on the meter. This is the primary resistance of the coil and should be between . 7 and 1.7 ohms.
What should the ohms be on the ignition coil?
So we obtain a multi-meter because my book on the car says you can test the ignition coil by ohming it out. (i should add we also bought a new rotor, distributor cap, and all new cords because the car needed it anyways). There is where i get lost… The book says it should be between 1.13-1.38ohms primary resistance.
What should secondary resistance be on Nissan coils?
This is the secondary resistance and should be between 7500 and 10500 ohms on most cars. Reconnect the connections to the coil if the test indicates a properly functioning unit. If the coil shows values outside the ranges listed, the coil needs further testing or replacing.
How to test small engine ignition coil with multimeter?
Testing a small engine ignition coil may look challenging, but it is reliable to accomplish it with the right guide. Do you know how? An ignition coil is actually a pulse-type transformer winded with two coils called primary and secondary and durably coiled over each other.
Do you need to worry about ignition coil resistance?
The small resistance differences you saw from the specs on the primary side of the coil are not too much to worry about since they can vary. You proved the coil worked at least when you first started it. Don’t let the coil get too hot as that can damage it.
How is primary resistance measured on ignition coil?
Primary resistance is the measure of how hard it is for current to flow through the primary windings. It is expressed in ohms (Ω). Resistance can be measured with a Multimeter. Set the multimeter to measure resistance (ohms). Connect the positive lead to the positive terminal of the coil. Connect the negative lead to the negative terminal.
What does K ohms mean on ignition coil?
If the readings in your post are accurate, you have at least one coil within the specification, (1.2 is within range) but the readings you report on the pickup coil don’t make any sense. “k-ohms” means “thousand-ohms”.
This is the secondary resistance and should be between 7500 and 10500 ohms on most cars. Reconnect the connections to the coil if the test indicates a properly functioning unit. If the coil shows values outside the ranges listed, the coil needs further testing or replacing.
