What voltage should a coil have?
The voltage reaching the coil may be 12 volts , or about 7 volts if the coil has a ballast resistor . Most electrical equipment works on 12 volts, but most modern cars have a resistor in the ignition system to assist starting. The coil in a ballast-resistor system is rated at 7-8 volts instead of 12 volts.
What voltage can a conventional ignition coil generate?
The ignition coil is a high voltage (low current) transformer that converts the vehicle’s 12 volt power supply to the 25-30,000 volts required to jump the gap of the spark plug, thus instigating combustion. With the development of engine management, ignition coils have undergone a complete redesign.
Should negative side of coil have power?
The power from the ignition switch need to go to the plus side of the coil and the negative goes the the distributor on a 12v system. That should be opposite what it was on a 6v positive ground.
What would be a reasonable voltage at the tip of a spark plug?
Spark plugs usually require voltage of 12,000–25,000 volts or more to ‘fire’ properly, although it can go up to 45,000 volts. They supply higher current during the discharge process resulting in a hotter and longer-duration spark.
Can a faulty ignition coil cause a Subaru Forester to stall?
Widely popular and ready to handle anything you throw at it, your Subaru Forester is the legendary compact crossover that continues to impress. What’s not impressive is engine stalling, thanks to a faulty ignition coil. Invest in a new Subaru Forester ignition coil from AutoZone to get the power you deserve.
How to test ignition coil resistance in Subaru Outback?
To check the ignition coil’s secondary resistance, connect an ohmmeter between the companion cylinder coil towers. First test cylinder numbers 1 and 2, then cylinders 3 and 4. The resistance should be between 10.4 and 15.6 k-ohms (?)
Where to get a new Forester ignition coil?
Instead of letting this problem linger, consider a new Forester coil pack at AutoZone. When you shop at an affordable auto parts retailer like AutoZone, you put yourself in a position to find quality replacement parts at competitive prices.
Is there a problem with the coil pack on a Subaru?
Note that many of the cases where ignition problems were had – people eventually discovered that the device that sends the coil the charge was the issue not the actual coil – so keep that in mind. If your having suspect spark issues. Pretty rare to see coil failures with Subarus.
