How to assess the ignition coil and secondary wire on Ford Bronco II?

To check the secondary wire and the ignition coil, begin by disconnecting the ignition coil connector and checking for dirt, corrosion, or damage. Use an already-known good coil and a spark tester to test for sparks. If a spark is present, measure the resistance in the ignition coil wire. Replace it if its resistance is over 7000 ohms per foot, if within specification, replace the ignition coil. To check for voltage supplied to the ignition coil, remove the coil connector and take readings at positive terminal of the ignition coil. If it is more than 90% of battery voltage, check through the ignition coil connector and terminals; otherwise, examine wiring or ign. switch. For measuring the primary resistance of the ignition coil with an ohmmeter, connect between positive and negative terminals of the coil. If this reading is between 0.3-1.0 ohms, then there is no problem with your ignition coils hence proceed to secondary resistance test, otherwise replace your ignition coils.

FordPartsDeal.com gives you genuine Ford Ignition Coil at some of the affordable online prices without cutting quality. Every OEM Ford part includes the manufacturer's warranty, easy returns, and super-fast delivery. So why wait? Shop now and get your vehicle back to peak condition.

Ford Ignition Coil sporadically jolts the battery voltage into a fierce spark that startles the engine. In 1913, Ford transformed the industry by moving an assembly line, producing cars at a better speed and cheaper rates so that ordinary people could afford one. Ford continues to drive that spirit with spirited EcoBoost engines that squeeze more miles out of every gallon and at the same time are not muscle-trimmed. Ford is stocking cabins with SYNC voice control, which allows drivers to play playlists or map out detours with both hands on the wheel. Ford piles on Co-Pilot360 and delivers battery-powered vehicles such as the F-150 Lightning, trimming fumes off the tailpipe without trimming it. The launch of the 1903 by Henry demonstrated that fearless concepts, alongside tenacious experimentation, can reverse the mechanization of movement of the planet. The outcome is a line-up that spans compact hybrids up to burly pickups that were designed to be driven and not shone in the showroom. Ignition Coil amplifies the twelve-volt feed as copper windings are wrapped around an iron core and the charge is released into the secondary circuit to the plugs, reaching up to 40,000 volts. There are forms of Ignition Coil, including the traditional distributor packs, coil-on-plug, and coil-near-plug designs, where each cylinder obtains the correct voltage without crosstalk. The symptoms of Ignition Coil fatigue include ignition sputters, weakened punch, and thirsty fuel consumption, thus drivers can immediately detect that sparks become weak. Ignition Coil swaps only require minutes and ignite again, propelling the engine to enthusiastic mile after enthusiastic mile on the city and open highway.

Ford Ignition Coil Parts and Q&A

Ignition Coil
F7PZ-12029-AA
Q: How to assess the ignition coil and secondary wire on Ford Bronco II?
A:
To check the secondary wire and the ignition coil, begin by disconnecting the ignition coil connector and checking for dirt, corrosion, or damage. Use an already-known good coil and a spark tester to test for sparks. If a spark is present, measure the resistance in the ignition coil wire. Replace it if its resistance is over 7000 ohms per foot, if within specification, replace the ignition coil. To check for voltage supplied to the ignition coil, remove the coil connector and take readings at positive terminal of the ignition coil. If it is more than 90% of battery voltage, check through the ignition coil connector and terminals; otherwise, examine wiring or ign. switch. For measuring the primary resistance of the ignition coil with an ohmmeter, connect between positive and negative terminals of the coil. If this reading is between 0.3-1.0 ohms, then there is no problem with your ignition coils hence proceed to secondary resistance test, otherwise replace your ignition coils.
