How many ohms should a 12 volt coil have?
You should have a resistance reading of at least 3-4.5 ohms. A bad coil will show a higher reading then 3-4.5. Next, place the red or black lead from the meter to the centre of the coil , and to either one of the terminals positive or negative. You want 9500-10000 Ohms, less is on but no more.
How many ohms should a ballast resistor have?
To test your ballast resistor you need an ohm meter or multimeter set to ohms. Remove the connectors from both sides of the resistor. The ohms should read between 1.8 and 5 ohms. You should be getting 9 volts to the positive side of the coil.
How many ohms should a 24v solenoid have?
Subsequently, question is, how many ohms should a 24v solenoid have? Generally, most solenoids measure between 20 and 60 ohms of resistance.
Why are there no figures for secondary resistance?
Even worse if it is one that sends a heavy signal down to measure the voltage loss in order to determine the resistance, that signal can fry the new chips. Some publish figures for the secondary resistance but as you can not test the primary , testing the secondary gets you no where.
What is the primary resistance of C oil?
Measuring C oil Primary Resistance: 4-Cylinder: Coil must have a minimum of 3 Ohms primary resistance. 8-Cylinder: Coil must have between 1.5 Ohms and 2.0 Ohms primary resistance. To measure primary resistance: Label and remove all wires to coil ( + or – ).
How much secondary resistance does a ignition coil need?
Measuring Coil Secondary Resistance: For best performance, coil should have 7K Ohms or more secondary resistance. To measure secondary resistance: Label and remove all wires to coil ( + or – ).
How much resistance should an OHV Coil have?
Trying to dignose an OHV v-twin. Bench tested the coils with an old analog ohmmeter, but not certain how much resistance indicates a good coil. Unless you are using a $ 45,000 signal generating testing machine your results are wothless.
