How Many Ohms Should A Coil Read. The Kill wire should read 0 ohms to the frame and between 2500-5000 between the ignition lead. Big relay 24V coil will typically have less resistance than the small relay 24V coil.
You check the relay coils resistance by taking a multimeter and placing it on the ohmmeter Ω setting and placing the probe leads of the multimeter on the 2 terminals of the relays coil. Before knowing the resistance we need to talk about the difficulties we face here. Connect your multimeter to the positive terminal or pin of your coil and to the high output terminal that goes to the spark plug.
Using an ohmmeter on the transformer-winding connection points as shown in figure 21634 ____ ohms would be read between X1 or X2 or H1 or H2 and the metal transformer enclosure.
The normal acceptable range for a standard 12-volt car is 15 to 17 Ohms. Big relay 24V coil will typically have less resistance than the small relay 24V coil. General rule of thumb is the lower the ohm lower the number the harder the hit more vapor warmer the vape and shorter the battery life before recharging. The isolation resistance between one of the coil connectors and ground should exceed 20G ohms.
